The electronic wake is a term that I coined a few years ago to describe the trail we leave behind ourselves in a wired society. For example, mobile phone calls, credit card purchases, smart cards, web browsing, CCTV systems, RFIDs, ATMs, all leave a track of where we have been and what we have been doing (and in some cases who we have been doing it with).
Recently, AOL has caused outrage by releasing part of that wake for general consumption. In early August AOL released the search logs for 658, 000 users, and has since been drowning in a torrent of recriminations, abuse, and threats of lawsuits.
Technology Review reports that the search logs were originally posted to a research site, and were removed once the manure hit the fan, but other sites have evidently re-posted the data. Although AOL changed people’s IDs to a randomised string, the nature and content of many of these searches may have made it possible to identify individuals. For example, people often search for their own names or for their home towns.
As an example of the sort of data that can be accessed News.com reported “it's possible to guess that AOL user 710794 is an overweight golfer, owner of a 1986 Porsche 944 and 1998 Cadillac SLS, and a fan of the University of Tennessee Volunteers Men's Basketball team. The same user, 710794, is interested in the Cherokee County School District in Canton, Ga., and has looked up the Suwanee Sports Academy in Suwanee, Ga., which caters to local youth, and the Youth Basketball of America's Georgia affiliate.
That's pretty normal. What's not is that user 710794 also regularly searches for ‘lolitas,’ a term commonly used to describe photographs and videos of minors who are nude or engaged in sexual acts.”.
News.com also reports the AOL apology “This was a screw-up, and we're angry and upset about it. It was an innocent enough attempt to reach out to the academic community with new research tools, but it was obviously not appropriately vetted, and if it had been, it would have been stopped in an instant,”.
The New York Times ran a story showing how it had identified a woman from Georgia, USA, just from her ‘anonymised’ search logs. The New York Times asked the lady for her views about what had happened and reported “Ms. Arnold says she loves online research, but the disclosure of her searches has left her disillusioned. In response, she plans to drop her AOL subscription. ‘We all have a right to privacy,’ she said. ‘Nobody should have found this all out.’”.
On the one hand, logs like these could be tremendously useful. Analysis by people like AOL Stalker have used the data to evaluate the importance of being in the top five items returned by a search, and show that 46% of these searches did not result in a click. Given that the number of users logged was 658,000 and included some 21 million searches, the base is pretty substantial!
On the other hand, the privacy concerns are immense. Most people were unaware that the big companies store all their searches. Almost everybody would have assumed that the terms that they had used in searches could not be traced back to them. And now they are aware, they seem pretty unhappy.
There are clear lessons for market researchers here. The first is the need to stay on the right side of the people we research, and the second is to make sure that we have the skills to work with this sort of information whenever it is legitimately available.
BTW, curious about how people like Google manage to keep your searches connected? Simple, they use a cookie. So, when you change machine or when you clear your cookies you break their link, for the time being.
