Facebook uses biometrics on photo images

20/12/10

Social networking giant Facebook is taking the plunge into using facial recognition-based biometrics in a bid to make it easier for users of the site to tag their photos.

In a blog by one of the company's engineers, Justin Mitchell, it was revealed that every day, people add more than 100 million tags to photos on Facebook. They do this because it's an easy way to share photos and memories.

Mitchell says in his blog that while tags are an essential tool for sharing important moments, many people find tagging photos a chore.

Mitchell said that since October, the company has been working to make this process easier. First Facebook added group tagging, so users can type one name and apply it to multiple photos of the same person. Now Facebook is announcing tag suggestions, which will make tagging multiple photos even more convenient.

The new systems will use face recognition software – similar to that found in many photo editing tools – to match new photos to other photos a person is tagged in. Facebook then groups similar photos together and, whenever possible, suggests the name of the friend in the photos.

Users can disable suggested tags in their Privacy Settings, if so desired.

The feature will be debuting tag suggestions to users in the United States over the next few weeks.
