AOL must have missed the uproar over the DOJ’s demand for “anonymized” search data last year that caused all sorts of pain for Microsoft and Google. That’s the only way to explain their release of data that includes 20 million web queries from 650,000 AOL users.

The data includes all searches from those users for a three month period this year, as well as whether they clicked on a result, what that result was and where it appeared on the result page. It’s a 439 MB compressed download, expanded to just over 2 gigs. The data is available here [UPDATE:they've removed the file] and the output is in ten text files, tab delineated.

The utter stupidity of this is staggering. AOL has released very private data about its users without their permission. While the AOL username has been changed to a random ID number, the abilitiy to analyze all searches by a single user will often lead people to easily determine who the user is, and what they are up to. The data includes personal names, addresses, social security numbers and everything else someone might type into a search box.

The most serious problem is the fact that many people often search on their own name, or those of their friends and family, to see what information is available about them on the net. Combine these ego searches with porn queries and you have a serious embarrassment. Combine them with “buy ecstasy” and you have evidence of a crime. Combine it with an address, social security number, etc., and you have an identity theft waiting to happen. The possibilities are endless.

Marketers are going nuts over the possibilities, users are calling for a boycott of AOL, and others are just enraged:

User 491577 searches for “florida cna pca lakeland tampa”, “emt school training florida”, “low calorie meals”, “infant seat”, and “fisher price roller blades”. Among user 39509’s hundreds of searches are: “ford 352″, “oklahoma disciplined pastors”, “oklahoma disciplined doctors”, “home loans”, and some other personally identifying and illegal stuff I’m going to leave out of here. Among user 545605’s searches are “shore hills park mays landing nj”, “frank william sindoni md”, “ceramic ashtrays”, “transfer money to china”, and “capital gains on sale of house”. Compared to some of the data, these examples are on the safe side. I’m leaving out the worst of it – searches for names of specific people, addresses, telephone numbers, illegal drugs, and more. There is no question that law enforcement, employers, or friends could figure out who some of these people are.

There is some really scary stuff in this data.

I am assuming that AOL will take this page and the data down soon, but as of the time of this post it has been downloaded 809 times already. People I’ve spoken with are already building a web interface to the data. If you are an AOL customer, I feel sorry for you.

Note that Microsoft has proposed releasing similar data to researchers, although with an important difference – the data is not associated with a user. Excite released data very similar to what AOL has done here, with user associations, in 1999.
