FACELESS: A German data protection official wants Facebook to delete biometric profiles of people stored without their explicit consent, saying they breach European privacy rules. In other words, he wants Facebook to delete users' faces from its databases.

ABOUT THE PROFILE: Facebook's photo tagging feature asks users to attach the names of people in pictures they have uploaded. Facebook then uses the unique facial characteristics in each picture to automatically identify the same person in other photographs on its site.

COMPANY RESPONSE: Facebook says it believes the feature "is fully compliant with EU data protection laws."
