The Norwegian Data Protection Agency is planning to launch an investigation into Facebook's facial recognition feature this fall, a spokesman said on Monday.
Last year, Facebook added the ability to use facial recognition technology to help to tag images as default feature to users worldwide.
"[Facial recognition] is a technology that it is important to have critical view of, and see how it is actually used," said Ove Sk
The agency plans to start digging into how Facebook's feature works, and have a dialogue with Facebook about it.
The agency will also have a discussion with Facebook about how it keeps track of instant messages between users, according to Sk
On both matters it is coordinating with the Article 29 Working Party -- an organization made up of a representative from the data protection authority of each E.U. member, the European Data Protection Supervisor and the E.U. Commission -- and the Office of the Data Protection Commissioner in Ireland, where Facebook's international arm is based.
The facial recognition feature isn't just getting attention by privacy watchdogs and advocates in Europe.
U.S. Senator Al Franken, chairman of the Senate Judiciary Committee's privacy subcommittee, at a July hearing called on Facebook to turn off the feature by default.
However, Facebook doesn't think that is a very good idea. Facebook is an opt-in experience, and people choose to be on Facebook because they want to share with each other, according to Rob Sherman, manager of privacy and public policy.
The importance Facebook places on facial recognition technology was shown in June when it purchased Face.com.
