Facebook has announced that it’s introducing facial recognition software which allows users identify friends in photos in a matter of seconds. Application Photo Finder can scan millions of photos quickly using recognition software therefore making it easier for users of the social network site to find pictures of their friends.

Facebook engineer Justin Mitchell in a blog post.”Now if you upload pictures from your cousin’s wedding, we’ll group together pictures of the bride and suggest her name,” Mitchell said.”Instead of typing her name 64 times, all you’ll need to do is click ‘Save’ to tag all of your cousin’s pictures at once.” According to the engineer more than 100 million “tags” are added to photos at Facebook each day.

Each time a Facebook user uploads a picture the software will match faces to those who have been tagged in other photos.

With the Tag Suggestions feature, Facebook will use its facial recognition technology to recognise similar faces and automatically suggest the name you should tag them with. Facebook will fill in the “Who is this?” box with its suggestion so that you just have to click the “Save Tags” button to accept.

Giving a nod to privacy concerns, Facebook said that users will be able to opt out of Tag Suggestions by going to their privacy settings and disabling the “Suggest photos of me to friends” feature.

The new feature is expected to be rolled out in the US within weeks.
