Privacy, Safe Harbor and ad blockers: When trust is key to business

Wild net neutrality vs. regulated standardized networks? Privacy for each vs. security for all? Free content with ads vs. pay-per-view? Are we bound to witness the development of the internet with the eyes of a war correspondent?

A few weeks ago, I have been at MeasureCamp in London, a bi-yearly analytics unconference that I find particularly stimulating (more about MeasureCamp here). I have held a session titled “More #Data, less #Privacy: Are we bound to finish naked?”. A summary of the discussion may be found here.

Provocative though the title may have been, the discussion was very constructive, and, as no clear solution seemed to emerge, it ended up with the only possible option, name it common sense, good will, mutual confidence… As for me, I shall keep the word “trust”, especially throughout this post for a good understanding.

Trust is is the common ground to the topics that I have named in the title of this post:

  • Privacy policies cannot be operative unless you trust the company storing your data, and in many instances, you may even call for a third party to handle this subject, which usually is called “trusted third-party”… A hot topic everywhere, especially with all the data leaks that have occurred in the recent weeks.
  • Safe Harbor has been put into question, and ultimately terminated by the EU Court of Justice, because trust had been broken between the US and Europe, not only because of the NSA spying scandal, but also of the divergent points of view about what the role of the Governments should be and their right to intrude into the business rules (see the endless debates on Net Neutrality and Right-to-be-forgotten, for instance on the NNSquad site)

  • Ad blockers also are starting to be an issue, because trust has been mishandled there too. Let us forget the original sin of third-party cookies, when accepting primary cookies from a website, for it to work properly, led to cookies being transferred to scores of third-party users, mostly for ad targeting purposes… My main concern today is about the latest bias in that area, i.e. ad blockers dealing with ad servers so as to generate exceptions for them, and let some ads be displayed, now breaching trust with their own clients.

Let me focus on this specific problem.

OK, ad blockers are standing in the way of advertisers, but so far they are not killing them. Advertising is the key monetisation tool for many free-to-access websites, among which media and news are in the first row, but many models show that such websites still may succeed nevertheless (the Huffington Post, as an example of a pure player, or the New York Times as an example of a redeployment from a paper business model). And, although we all agree that purely free content may only be amateur, plagiary, or infomercial, still ad blockers are not threatening free speech and democracy. And some people may require some rest from all-too intrusive ads, and block them. That’s legitimate.

Still, those same people have to behave accordingly, and understand that not everything may be free. Economy is give and take, debit and credit, buy and sell. These people have to pay for added-value content, beyond Linkedin Pulse summaries, or Mediapost digest e-mails. Pay for an abo at the NY Times on-line for instance. It balances the loss of revenue (ad-blocking) for some websites with paid-for content, for instance news read behind a paywall. This is fair. This are good business rules. This also is all about trust.

Trust is when both sides do their part; trust is when people using ad-blockers buy content somehow; trust is when an ad-blocking software reminds you that not everything may be free on the web, and that you have to pay for some content; trust is when ad-servers are serving relevant ads in relevant quantity, not flooding us until we surrender (or block).

But trust is broken when one of the parties is not playing a fair game; trust is broken with the users when an ad-blocking companies sells, at a very expensive price, bypassing ways for some ad-servers. Trust is broken when little arrangements are made between ad-blockers and ad-servers behind the back of the flock of consumers.

I shall not elaborate more about ad-blockers and especially about the AdBlock deal (more details here). And though this ad-blocker is a tool I have recommended in the past (in this 2014 post, for instance: Data Privacy, between a rock and a hard place), trust is now broken. And breaking trust means losing clients. At least some clients. AdBlock, you lost my trust, you lost me.

Dynamic Clustering, a new ad targeting methodology

This article is a summary of my proposed methodology to targeting web users with relevant ads, but without intrusion, e.g. without third-party cookies. The original version, including a broader depiction of the context, is a longer post in French : “Le régime sans cookies, le nouvel âge du ciblage sur internet

Basically, as related in many articles, including previous posts on this blog (see for instance “Giving up cookies for a new internet… The third age of targeting is at your door“), the usage of third-party cookies is bond to dwindle, if not to disappear. Some solutions have already been submitted, such as fingerprinting (still intrusive though) or unique identifiers (but too much linked to the major existing internet companies).

So, we need a non-intrusive contextual targeting solution, which takes privacy protection into account. This is the core idea of my proposed solution, e.g. “dynamic clustering“.


How does it work?

  1. Based on ISP and/or Operator log files, browsing data will be collected and anonymized (for instance through a double-anonymization filter) so as to protect one’s user privacy; Anonymous
  2. Files will be cleaned (“noise-reduction” processes), and organized at various categorization levels, so as to generate multiple dimensions, all of them rich and flexible. This will allow to create “outlined profiles” for each unique anonymous user; Categorization
  3. Using these dimensions, clusters will be generated, made of users with similar usage behaviors, based on each advertiser’s hypothesis, creating hence an infinite number of target groups, whose volatility is an asset, as it will always cover the client issue of the given moment.

ClusterSo yes, the no-cookie diet is possible… And it goes along with a more virtuous targeting of the internet users…

Convinced by this new diet? Willing to collaborate to the recipe development? Let’s meet!

When the State sells your personal data…

…it is with the Privacy Authority blessing!

This case is typical of the current French system, but this may echo some concerns elsewhere, so I have made a summary of an original post in French, so as to trigger discussion…

Basically all French politicians are claiming they want to fight the Privacy breaches, especially when North-American internet companies are involved. Still, the findings are clear: the French State and its state-owned companies are doing exactly the same!

First, the rule: any form collecting any of your (personal) data is to offer to the users the ability to give or refuse consent, regarding any further use of their data. In France, this is clearly stated in a law, passed as early as 1978 (named “Data Processing and Freedom”, a full concept in itself…).

There are two possible questions (“opt-in” or agree, and “opt-out” or disagree) and two ways of offering the answer (“active” and “passive”); this implies four different ways of collecting any consent (see table below), and of course generates confusion.


The “passive” response mode is neither common, nor recommended in France (even if it is not forbidden, as far as I may know), but it is more often found on US websites. In this case, the check-box is already ticked, and the user’s answer is registered by default. To register another choice, one has to un-tick the check-box. Clearly this option may only be used online.

For paper forms, one may focus on the “active” mode, when a check-box has to be ticked. The two remaining options are:

  1. Active opt-in = the user agrees, by ticking one or several check-boxes, that his/her personal date may be stored, reused, transferred, sold to third parties. This is the most respectful mode for the user, as only active opt-in guarantees that the user has chosen to give away his/her data. But this is not the norm…
  2. active opt-out = the use disagrees that his/her personal data are used, still by ticking a check-box. This mode is the most commonly used in France, and the Privacy Authority (CNIL) implicitly endorses this behavior. On its website, namely in the Q&A section of their website (only available in French), the CNIL mentions that the user may “oppose” to personal data transfer to third-parties or “refuse” that such data be used for commercial purposes. they endorse the opt-out mode.

Of course, many user just forget to tick check-boxes (or worse, do not find them), and hence are included by default on files sold to third-parties, namely for business purposes. This may be understandable for private companies, but when it comes to the Government or to State-owned companies, this is more disputable!

I have covered two examples in the original French version of this post, taken from recent experiences, that I believe may not be of interest for non-French speaking people. My comments are backed up by solid material.

Hence, the French State collects – and resells – personal data from its citizens, while Google, Amazon or Facebook are blamed for doing the same… You mean “contradiction”? I say “opportunism”.

For a true personal data protection, one has to develop alternative targeting tools! “Fingerprinting” or “unique identifier”, are mentioned, but there also is a non-intrusive option, based on the user’s online behavior. I am working on it… Willing to know more? Stay tuned and come back next week on this blog!

[This post is a summary of a longer original version written in the French-speaking section of; the original version in French namely includes pics and explanations of two opt-out examples]

Data Elicitation in three steps (1/3): Data Patterning

In my previous post, I have outlined what Data Elicitation was about. I have introduced the three areas required for a proper eliciting process, e.g. Data Patterning, Data Enrichment, and Data Analytics. This post will deal with the first of these areas, “patterning“.

First, it is worth explaining why I chose this word. I have used a typical concept from the textile industry (or, to be a bit more ambitious from the “Haute Couture” world). In this area, a pattern is the intermediate stage between the designer’s sketches and the item production, a formalized plan enabling industrial planning. On one hand, it still is a concept, like the sketches, as it is purely paper. But on the other hand, it already is production, as it includes all the necessary information for implementing a full production process. This is what patterning is all about, allowing people’s ideas to become physical shapes.

Patterning data is an essential step for data management,as it allows to take stakeholder wishes and technical constraints into account, and prepare an optimal project and development planning.. No database is suitable, if not driven by clients’ needs and requests. No data analysis is relevant if not aligned with the previously agreed pattern.

A few key questions in this respect:

  • What are my data made of and, even more important, made for? → as one finds its way better when the ultimate goal is known…
  • How can data sets be best organized? → the proper content ought to be in the proper place
  • What content do I need to store to get the best out of my data? → since not every piece of information may be worth keeping
  • How may my data relations be best optimized? → data are more useful when they are properly linked and aligned

I have summarized a typical process in the table below, in three columns; a fashion analogy, some project management steps and a basic (softened) example inspired by one of my previous experiences in the mobile world:

Patterning steps

The parallel with the creative flow in the Fashion industry is strong, as it shows that the first half of the process (steps #1 to #4) is the true added-value to the whole content, the second half being more execution. It is clear that botching the patterning phase will impede the proper completion of the project. In the case above, the proposed solution could be summarized in a small chart, as the information laid in two fields of the provided log files.

Patterning chart

The two attributes (fields) that were present in the log files are marked here in blue.

The TAC (the first part of the IMEI code) may be directly used, as it relates to one device model; the master database is maintained by the GSMA, and is delivered to its members (including Telecom Operators).

The User Agent is more complicated, as it includes entangled information; parsing the User Agent will allow namely to identify browser, OS and type of connection that have been used. Still, it does not require additional information, only a good content analysis and a solid set of coding rules.

The combination of these four items creates a unique identifier, which is not specifically related to given users, but creates homogeneous groups, sharing similar technical conditions (hardware, software, network). Each group will then receive contents adapted to their specific conditions, thereby optimizing their browsing experience and consequently increasing engagement.

As this blog is aiming at a large public, I chose to keep a rather simple example. Of course, should the matter be more intricate, the skills I have built up over my years of experience in Data Management will even be more valuable. Feel free to ask more about patterning or other fields of Data Elicitation, I shall be glad to elaborate customized solutions for your business.

Analytics without cookies? My follow-up to #MeasureCamp IV

As mentioned in my previous post “Giving up cookies for a new internet… The third age of targeting is at your door.“, I have attended the fourth Measure Camp in London (, on March 29th. And my (voluntarily controversial) topic has been: “Web Analytics without cookies?

The subject has been introduced by the following three charts, a short introduction to what I expected to be a discussion, and a hot one it has been!

Measure Camp IV (post)

Basically, the discussion has been getting around three topics:

  • Are really cookies going to disappear, and if yes which ones and how?
  • Are cookies disapproved by the users because of their lack of privacy or rather because of some all-too aggressive third-party cookie strategies?
  • Are there any solutions, and when do we need them at last?

Topic number 1 definitely is the most controversial. It already is difficult to imagine how to deal without what has been the basics of collection, targeting and analysis. On top of this, some valid objections also have been given, such as the necessity to keep first-party cookies for a decent browsing experience as well as the request from a fair share of the users to keep ads, providing they were relevant to them. A very good follow-up has been brought by James Sandoval (Twitter: @checkyourfuel) and the BrightTag team. Thanks to them for their inputs.

Clearly, the participants were all agreeing that a cookie ban would only impact third-party ones, and occur for political reasons (maybe not before 3 to 5 years), lest a huge privacy scandal ignites an accelerated decision process. Still, a fair amount of the internet revenue would then be imperiled.

At this stage, there still remains the acceptance of cookies by the users. There is a wide consensus within the digital community that people browsing the internet accept a reasonable amount of cookie intrusion in their lives, should this generate relevant ads. Actually, I think this view is biased, as nobody has ever asked whether people would rather browse with or without ads… The question always has been between”wild” and “reasoned” ad targeting… It reminds me of an oil company asking if car drivers would rather tank diesel or lead-free, not allowing “electricity” as a valid answer…

So the question of cookie acceptance remains open in my eyes, and this may be a key driver to designing alternative solutions.

What options do we have at hand then?

The first and blatant one is a better regulation of third-party cookies, especially the ability of the user to master how, when and with whom their first-party cookies could and should be shared in an opt-in mode. The law (in the EU) theoretically rules this (see EU rules about cookie consent here), through a warning to the user about cookies, when he or she opens a new website. Still, national transcriptions and various ways of web page developments have made this law non-understandable, and mostly not actionable on a global basis.

A first step would then be to abide by the user’s choice, and give him the ability to manage his or her own cookies, sharing some, all or none of them with third-parties, as they wish. A difficult task, especially when nearly 30 government bodies are to be implied… So why not investigate non-cookie options?

In London, I have introduced two possible ways:

  1. Create a unique Id for each user, somewhat like Google’s unique Id, but managed by an independent body. My suggestion is that such an Id should belong to the whole community, like HTML or HTTP… A huge task.
  2. The other idea is mine… It would consist of the generation of anonymized profiles, based on browsing patterns. This idea I shall develop more in detail in future posts, but the idea is worth thinking, especially when one imagines that today’s user mood may not be tomorrow’s, and require a very dynamic targeting methodology…

So this hot discussion on cookies at least has initiated discussions among the digital community. It also proved that such fresh (and sometimes idealistic) views as mine are necessary to keep the digital community staying on the edge of innovation. So stay tuned, I shall go on providing food for thought so as to “shake the tree” of Measurement…

Giving up cookies for a new internet… The third age of targeting is at your door.

While preparing next week’s Measure Camp in London (, I had been wondering what would be the most interesting topic in my eyes. And my question is: “How would Web Analytics work without cookies?

Actually, last year, in September, I had read an interesting post by Laurie Sullivan, posted on the site: “Where The Next Ad-Targeting Technology Might Come From“. This had been the core of my thoughts for the past months, so I wanted to elaborate on Laurie’s post so as to introduce my own ideas about this topic.

I personally believe that the mean of collecting information from the web users through cookies is fading and soon to disappear. There are many reasons for this, including the user privacy concerns, the lack of contextuality of the cookie as well as the development of multiple access point and devices, that render such a data collection highly hazardous.

The disappearance of cookies would have an impact on at least three areas: data collection, targeting and analytics.

  • Data collection is highly based on cookies, especially when dealing with ad exposure and browsing habits. High impact.
  • Targeting is also based on cookies, as most tools use history to handle their most likely customers. High impact.
  • Analytics are also using cookies, especially for site-centric analysis as well as various page-level analysis. High impact.

Considering the high impacts, time has come for a more contextual and more behavioral targeting. We are now entering the third age of targeting. The first age had been based on sociodemographics, widely used by TV Ads or direct post mailing. The second age has been based on using past behavior to predict potential future actions, and, in internet, is widely using cookies to pursue this goal. The third age will be the age of context, targeting anonymous users with current common interests.

How will it work? One possible way: we would use network log files (provided by ISP’s or Telco’s) to collect data, organize these data with a categorization at various levels and through multiple dimensions so as to generate rich but heterogeneous user clusters and hence allow targeting of potential customers based on ad-hoc inputs. I shall elaborate in further posts, especially regarding the process, but the main advantage is the respect of privacy, especially thanks to cookie avoidance…


So, yes, giving up cookies may be difficult; this is why I believe we ought to prepare to go on a diet as of today…

And act for alternative methodologies instead of shouting “me want cookies!”

Data Privacy, between a rock and a hard place

How are we to handle Data Privacy? Through goodwill, as original free internet promoters would like to? Or through coercive regulation measures, as government bodies are prone to? This definitely is no easy dilemma…

The Marketing Mobile Association in France has been willing to put the question on the table, last Wednesday (Feb 12th), on the very same day when the US were having the so-called “safer internet day”. The meeting venue was more on the goodwill side, as the event has been hosted by the Mozilla Foundation in their Paris office. A nice place, by the way, see for yourself…

Mozilla Meeting Room

The discussion panel was more balanced, with Etienne Drouard attorney at K&L Gates, specialized in Privacy matters, and Geoffrey Delcroix, CNIL Innovation Director (CNIL being the French Internet Regulatory Body), as well as Hervé Le Jouan, CEO of Privowny, and Tristan Nitot, Principal Evangelist Mozilla Europe (a brilliant coffee brewer as well…), the whole thing being moderated by Bruno Perrin, Media & Entertainment Leader at EY.

Between tools to manage oneself’s privacy (see my own selection at the bottom of this post) and various comments to the Privacy Laws, the main impression that remains from this panel discussion is that handling Data Privacy is like walking on a tight rope…

Two opposite views are currently cleaving the internet:

  • On one side, the “libertarian” internet promoters, with their concepts based on freedom as wide as possible (net neutrality, open data, open source, etc…), whose view of privacy is linked to each person individual right to protect one’s privacy. A global “do-not-track” by default would certainly please them, especially if companies are to respect it forcefully…
  • On another side, at the opposite of the scope, we have the state bodies, willing to set more control on the internet, as this is something that they do not only misunderstand, but also fear; in this respect, they wish to instate regulations, privacy by design, control over content, etc…

And, in the middle, the so-called “new economy”, all these companies and people trying to make a sensible use of the internet… Not easy, mmh? What I understood very clearly from the panel discussion is that none of the extreme behaviors depicted above would give internet a chance. Setting “do-not-track” by default would simply lead companies to ignore it, and hence kill the idea. And on the other side, regulating the market by law would technically make it die, in the end. Hence, the tight rope strategy is the only one that remains, with a difficult balance between market freedom and people’s protection, between business and privacy…

So what are we left with? We can try to manage our own privacy, and ensure it does not go beyond the borders we have set. Nobody lives in a cave with no contact to the outside any more (as this would probably be the only way to fully protect one’s privacy…). But nobody wants to live constantly under the eyes of watchers, as in a personal Truman Show, especially when your information is wanted for their business… We may go on using internet, conscious that we are watched, but managing this, and knowingly give our consent wherever we believe it makes sense, blocking all other non-sollicited requests…

There are many tools to do so. Probably too many. I personally use five.

  1. An ad-blocker: this is not a must have, but it may be useful , especially to speed up your browsing. I use AdBlock, a Chrome extension. The disadvantage of this, is that most ad-blockers do not offset the changes in the layout of the website, making it sometimes barely readable (as for instance my favorite sport page, Sport24). And do not forget that most sites earn their money thanks to the ads… So I disable it now and then, especially when visiting sites with less audience.
  2. A user/password manager: this is highly interesting, to ensure you know what and where you have been logging in, and ensure nobody is using some of your identities without you knowing it. I am using the Privowny tool bar, a very useful add-on.
  3. An identity verifier: this is for Twitter in particular. To avoid being followed (and spammed) by robots and fake followers, I am using TrueTwit, a simple (and not so expensive) tool to filter and verify any Twitter user. I have less followers now, but only real people…
  4. A do-not-track option: I also use, now and then, the do-not-track feature in my browser (Chrome). This I do especially when shopping or banking online, so as to minimize the amount of cookies shared by these companies that also own very personal information of mine. I know, this is more a wishful thinking, but at least shows that I am not ready to let everything leak.
  5. A graphical cookie tracer: I have uploaded CookieViz from the CNIL website, a free software to visualize your browsing, and the cookies that have been shared with third parties. At least, when you browse websites, including your favorite ones, you know what you are at… Below a short description of this tool (currently only available for Windows OS, soon to come for Mac and Unix).

CookieViz example

The picture shows a session for 7 browsed sites (9 views total). The 7 websites are “circled” with red pentagons. Up right is Sport24 (link provided above), below e-commerce website and information website

At the bottom, from right to left, a gaming website, my profile and this blog’s dashboard page. In the middle, Avinash Kaushik’s blog (Occam’s Razor), showing that even the blog of a respected digital evangelist like Avinash may share third-party cookies…

The graph is, I believe, self-explanatory; the visited websites (red pentagons) are generating cookies (all blue round spots), which are kept for first-party usage (blue links) or shared with third-party (red links). To be clear, I have disabled the AdBlock to generate this graph, so as to prevent partial representation.

This tool is highly interesting in my eyes. It does not block anything, but shows you everything. At least, the user knows what happens when he/she visits a website, and may decide to go on browsing, or choose alternatives websites with a better sharing policy, especially regarding third-party cookies.

A better informed customer always makes better choices.

Generation C: being forty-something may be trendy again…

Generation C. Gen C. A new buzzword, announcing the downfall of the Generation Y (which itself outdated Generation X a few years ago…). And definitely, the sign that, in our digital world, the age barrier, along with other old-fashioned sociodemographic factors, is tumbling down.

What are we talking about? The C stands for “connected”, but also for “creative”, “communicative”, “collaborative”, and its activities are driven by two other c’s, “content” and “cloud”. What is interesting in this new concept, is that it is not related to the age of the user itself. Generation X and Y used to refer to educational schemes, the X one driven by the upsurge of TV in our life, through numerous channels and dedicated programs, while the Y one was linked to the computer penetration in our homes along with the spread of an ever easier internet access and digitalized exchanges. For a parallel comparison of Gen Y and C, a very good read is “Gen C, Gen Y, Gen who?” by Jake Pearce.

Gen C is different. It is driven by usage, beyond age, education and culture. This implies at least two major consequences for the matters I like to deal with.

In the first place, this is another sign for the  lack of relevancy of sociodemographics. It is now clear that the target for marketing campaigns cannot be defined solely on the basis of age, gender, geographical location or whatever predetermined personal attribute. Target ought to be meant as a group of common interest, sharing same habits, same interests, same fads… This is Gen C vs. X or Y. How we may achieve a satisfying targeting is another (huge) question. Basically the issue may be summarized as follows: “cookie or not cookie?”, and I shall deal with this matter in future posts, showing how a long-life clustering and targeting methodology is to be performed without cookies, especially in this era of acute privacy concerns.

In the second place, then, I believe that the emerging Generation C is a sign for a new deal in Human Resources Management in the marketing area, especially where digital and new technologies are concerned. I have attended a Club Digital conference in Paris last Tuesday (Nov 5th), whose subject was “Recruitment and Career in the Digital Business: key factors of success” (more info in French on, or on Twitter with keyword #DigitalFR). One of the key learnings is that an efficient digital strategy is to be a mix of design and technique, of guidance and execution, of marketing and IT. So of course Digital Natives in their early twenties are badly needed, but on top of their knowledge, some additional experience is required… Guidance, organization, management, in a few words, alignment with the company’s strategic resources at high level (marketing, human resources, finance, sales…) is also at stake. Understanding business challenges, deciphering client needs, organizing data management may imply more than academic expertise. And for this, one needs seniority, some business acumen, in a few words, people having already lived successful challenges, as well as experienced failures, that taught them lessons…

Thus, according to the members of the conference panel, forty-something year old Generation C managers are even a scarce resource, as the need for digital resources is immense, and the share of experienced senior managers in this area very tiny. The Geek world is now ready to welcome Oldies Goldies: this is really good news!

With my Windows phone always connected to the world, an in-depth expertise in big data management, along with my digital experience,  I should be considered as a trendy forty-something year old manager. Good start, isn’t it?


The Great Discoveries, the Enlightenment and the Internet

A few weeks ago, I have been discussing about cookies while working on an assignment for my one of UBC Award of Achievement in Digital Analytics module and I had an interesting argument about comparing one’s personal computer to a home, and beyond this to the fact that the internet development is a real revolutionary spread.

Actually, this comparison makes sense, as far as you consider your home for what it is, i.e. your home base before and after any possible journey you would make, for work, leisure, shopping, vacation… Your computer is like your home, only if you do not walk outside, i.e. only if you do not connect to the web. Browsing is like going outside, to shops, to leisure activities, to theaters, to restaurants, and there, people collect constantly your own personal information.

Considering the privacy issue on my computer, I have especially focused my thoughts on the cookie management, a difficult balance between a good browsing experience and an all too present advertisement intrusion. It is similar to any visit or phone call to my home, as I would not want to tell or show too much, unless I have cleaned my floor, hidden what I would not want others to have a look at, or set my mind to “politically-correct”…

There is a schizophrenic behavior of users requesting an ever improved speed and usability for the websites, but grumbling against the website adaptation to the client’s browsing preferences, in a “but how do they know so much about me?” mode. As far as I am aware that I give up some of my privacy, allowing first-party cookies to improve my own user experience through increased page loading speed and saved preferences (such as passwords on on-line gaming sites or pre-entered Personal Information on e-shopping ones), this is fine: I do accept them freely, wherever they make sense, i.e. when they offer a real service to me. On small exception, when accessing “sensible” information (Online Banking or Tax Payments), I usually activate the “do-not-track” option, which is supposed to prevent the website from collecting cookies. So far so good for my online privacy.

In parallel to my home, I just lock it with a key, draw the curtains and lock the shutters, and my home privacy is also safe. Still a personal computer cannot be a stand-alone object any more, with no connection to the outside world, just like no one would ever stay at home all of his/her life. A computer is very much like one’s life, in constant interaction with outside inputs and outputs, and hence everyone has to acknowledge that data are collected about oneself, one way or the other.

Beyond the debate about how to manage cookies and whether they should be more strictly ruled (I may handle this later), I believe that we are anyway at a turn of history, a moment when the technology itself (internet, broadband, mobile, NFC, GPS…) is altering the very way we behave.

To refer precisely to my post title, I believe we are at a turn of tides, like at the times of the Great Discoveries in the 15th and 16th century, when we got to learn about other worlds, or those of the Enlightenment, in the 18th and 19th century, when the emergence of new ideas, as well as the tremendous progress of transportation, meant no one in the world could remain hidden from others. In this respect, the internet (and its multiple technological spin-offs) brIngs a new era of openness to the world, as one may not only be aware of new ideas or have the possibility to go and see other people and culture, but in a more efficiently manner, anyone may now summon anything and anyone to his own couch, through the power of a connected device…

This is like my home actually, as in the Middle Ages, it was totally isolated in the middle of the nowhere, and then someone discovered the way to it, then an enlightening road was built, and now, a full connected town is growing around my place. My behavior, and my relation to others will definitely be altered, as well as the depth of the knowledge they will be able to gather about me (and me about them)…

The Great Discoveries led to the fading power of the Catholic Church in Western Europe, as well as the possibility to travel enriched the revolutionary ideas of the Enlightenment… So is also the internet revolution, it changes our relationship to the world, to others, and even to ourselves!

it goes without saying that any revolution has its drawbacks; like the Revolutions from 1789 to 1917 have led to massive kills of “Ancien Régime” people, the internet is unfortunately not only nibbling our privacy, but also killing some traditional activities (Physical Cultural Media, including paper, CD’s or tapes, Brick and Mortar retailing…). Still, the same Revolutions brought new rights to the majority of the people (Liberty, Equality, Fraternity), just like the internet now allows equal rights and access to education, information, services, products… I do believe in the positive change that is brought by the latest technologies. Let us just remind ourselves that the internet only is a mean to reach a more comfortable world…

Jumping over the data privacy fence to land on the optimization green grass? See the hurdle?

Back to school today. Back to work. But back to school also meant back to my desk and also to my usual good reads.

I have namely read this post today, “Beyond Privacy Exploitation Lies Huge Opportunity For Personal Data Optimization” by Max Kalehoff on MediaPost, and I believe he is going a bit quick from his own personal point of view to a more general standpoint. Nevertheless, it is a good starting point for a post about data collection management.

The general idea, e.g. people could share more data for a more optimized benefit, is nice, but only the first part is convincing, i.e. there still is a lot of unexploited data to share. As it lacks some proposal on how one could “optimize” personal data, here are some thoughts I have had on this topic.

Max’s story is nice, but his reasoning by induction is not correct. Not everyone is ready to share really personal data, like weight or daily burnt calories… Actually, this is most probably the reverse way… Such data would most probably be hidden as much as possible, and its distribution highly limited to the lowest number of people, e.g. to none but the data owner himself… A marketer may dream of openness in such a case, but unfortunately I think this is far from real life.

And still, should anyone be ready to share such very personal data, would the distribution list be very large? I doubt so… A few friends and relatives, some key helpers (a fitness coach, a Weight Watcher Leader…) and maybe a doctor, that would be it. The “challenge” idea is typical of someone leaving well with his/her weight, and only willing to lose a few pounds for a healthier life. Not the majority of people dealing with overweight (or with any other personal problem, that is). And most probably a very narrow minority, I guess.

But the idea remains of the highest interest: get passively collected data to create a huge database with a maximum of objectivity. The daily routine for Market Researcher operating in the Retail Panel Tracking, but very seldom when it comes to people. Why this? Because people are aware that they are being tracked, and this only fact introduces a bias (I remember the famous bias of Consumer Panels, where no woman would ever buy any feminine hygiene item, and no man any condom…). Where there is uneasiness or even shame, there will be no freely shared data. So what are we to do?

In this area, what is the absolute must? Not only the passivity of the data collection, but also the ignorance of the tracked people. The less they know they are tracked, the more objective the data. And no question. A marketer’s dream come true. Of course, this is very cynical, and dangerous for the company acting like this, as no panelist will be asked about their consent (or, blatantly, they would be aware they are being tracked…). If I refer to this post’s title, this would mean to reduce the privacy fence to its lowest height, so as to be able to walk over it, not even jump at all…

But this will not happen. The hurdle is high and will remain such. It is built by conduct codes, regulations, even laws, and may very difficulty be ignored. So tracked people ought to know their data are collected. And objectivity will be lost. How to get over this? Find people ready to share their data, have them on board of a panel with an opt-in clause, and run some analysis. A classical methodology to ensure privacy is not breached. The risk? A panel based only on clones of Max Kalehoff, introducing another bias, the will to be tracked…

So, is there no way to get over the fence? There are some of course. The cookies on the web are probably the most famous af all. Every website uses some. And they are (very) intrusive. And some people started to complain, and even to request they should be blocked or erased. A solution will be required here too for user targeting and browsing behavior optimization.

So Max, I do not have the solution either. Not yet… But I’m working on it.
