Anonymity of Netflix Prize Dataset Broken 164

Posted by Zonk from the there-are-degrees-of-anonymity dept.
KentuckyFC writes "The anonymity of the Netflix Prize dataset has been broken by a pair of computer scientists from the University of Texas, according to a report from the physics arXivblog. It turns out that an individual's set of ratings and the dates on which they were made are pretty unique, particularly if the ratings involve films outside the most popular 100 movies. So it's straightforward to find a match by comparing the anonymized data against publicly available ratings on the Internet Movie Database (IMDb) (abstract on the physics arxiv). The researchers used this method to find how individuals on the IMDb privately rated films on Netflix, in the process possibly working out their political affiliation, sexual preferences and a number of other personal details"

Microsoft Vista, IE7 Banned By U.S. DOT 410

Posted by Zonk from the that-is-a-serious-buzz-harsher dept.
An anonymous reader writes "According to a memo being reported on by Information week, the US Department of Transportation has issued a moratorium on upgrading Microsoft products. Concerns over costs and compatability issues has lead the federal agency to prevent upgrades from XP to Vista, as well as to stop users from moving to IE 7 and Office 2007. As the article says, 'In a memo to his staff, DOT chief information officer Daniel Mintz says he has placed "an indefinite moratorium" on the upgrades as "there appears to be no compelling technical or business case for upgrading to these new Microsoft software products. Furthermore, there appears to be specific reasons not to upgrade."'"
