Deceptive Assurances of Privacy?
Earlier this week, Facebook expanded the roll-out of its facial recognition software to tag people in photos uploaded to the social networking site. Many observers and regulators responded with privacy concerns; EFF offered a video showing users how to opt-out. Tim O’Reilly, however, takes a different tack: Face recognition is here to stay.

New Research Result: Bubble Forms Not So Anonymous
Today, Joe Calandrino, Ed Felten and I are releasing a new result regarding the anonymity of fill-in-the-bubble forms. These forms, popular for their use with standardized tests, require respondents to select answer choices by filling in a corresponding bubble. Contradicting a widespread implicit assumption, we show that individuals create distinctive marks on these forms, allowing…

Tinkering with the IEEE and ACM copyright policies
It’s historically been the case that papers published in an IEEE or ACM conference or journal must have their copyrights assigned to the IEEE or ACM, respectively.

Debugging Legislation: PROTECT IP
There’s more than a hint of theatrics in the draft PROTECT IP bill (pdf, via dontcensortheinternet ) that has emerged as son-of-COICA, starting with the ungainly acronym of a name. Given its roots in the entertainment industry, that low drama comes as no surprise. Each section name is worse than the last: “Eliminating the Financial…

Don't love the cyber bomb, but don't ignore it either
Cybersecurity is overblown – or not A recent report by Jerry Brito and Tate Watkins of George Mason University titled “Loving The Cyber Bomb?

Not satisfied with seizing domain names, the Department of Homeland Security asked Mozilla to take down the MafiaaFire add-on for Firefox. Mozilla, through its legal counsel Harvey Anderson, refused.
