Face control: Before Facebook's photo-identification, there is little escape

Facebook knows your face: The social network has introduced a new feature for automatic image recognition - which can be switched off only with difficulty. Completely escape the user's face scanner itself does not. Hamburg - Every day be tagged with Face Book 100 million photos: users select where in the picture a person is, Facebook then linked this with the appropriate profile.

To make the users to tagging as easy as possible, try Facebook, people to see on photos automatically. When struck an appropriate selection is proposed. Because the new feature is on by default and users have not indicated they were showered with criticism. He was hoping for a privacy-friendly setting, the Hamburg Data Protection Officer John Casper said on Wednesday.

"So, how the system is regulated, the transparent to the user." After all, the automatic suggestions only work in their own Facebook friends, but not beyond. In addition, users pointed out a marker and can remove them easily. The proposals can be automatically switched off in the settings, with seven clicks.

But face recognition is still not miss it. Facebook compares the similarities in the photos on which a user is selected. A summary of this comparison, called "combined photo information" is stored. If a user was never marked on a picture or has all the markings removed, no summary is saved.

The profile photos are not automatically considered as a Facebook spokeswoman told on request. In order to avoid the face recognition and not having to give up all the photo tags, Facebook users have the company send an e-mail. Then the "combined photo information" deleted. But then when tagging Facebook friends a person again and again and this person deletes the markers, is the Speicherei from the beginning.

"Always nice smile," advises blogger Richard Gutjahr all Facebook users. For a way to switch the photo markers in general, one seeks in vain. If you wanted to renounce the right to be tagged by their own friends, you could tell this to friends, a Facebook spokeswoman said on request. Furthermore, visibility of markings on the selected users will be self limited.

The complicated details are plentiful. Facebook itself has then rather to the fact that the introduced in the U.S. months ago, face scanner has been proposed tens of millions of marks that have been accepted tens of millions. Finally, the company sees the image recognition not a privacy issue, but a useful help function.
