Facebook May Track Users Who Leave Service, Data Agency Says
Facebook Inc. may be tracking users’ Internet activity even after they cancel their accounts with the social-networking site, a German privacy watchdog said.
“Arguments that all users have to remain recognizable after they leave Facebook to guarantee the service’s security can’t stand up,” Johannes Caspar, the Hamburg data protection representative, said on his agency’s website. “The probe raises the suspicion that Facebook is creating user tracking profiles,” which would be unlawful if users aren’t alerted.
The German regulator’s action adds to probes of Facebook by the Irish data-protection agency and Norway’s privacy watchdog. A group of EU regulators has said they will look for possible privacy violations in Facebook’s facial-recognition feature.
Remaining cookies are used in “identifying spammers and phishers, detecting when somebody unauthorized is trying to access your account, helping you get back into your account if you get hacked,” and blocking underage users from re-registering with a different birth date, Facebook said.
The willingness of the company to “enter into a discussion” on the technical processes was a positive step, the regulator said, and urged Facebook to contribute to a “transparent and public” clarification about the cookies and move toward a solution in line with the law.
Cookies are created for each new Facebook user and some are maintained when a user leaves the service. The cookies are stored for two years and can clearly identify users during that time, said the Hamburg regulator.
