Facebook is rolling out new privacy settings so users can control who sees each individual piece of content created or uploaded, but what about untagged photos? If a friend uploads a photo of you but does not tag it, you may not even know it’s there.

An app from Face.com, Photo Tagger is extending Facebook privacy control to photo sharing with a new feature: Face Alerts. A feature of the bulk-tagging application Photo Tagger, Face Alerts is the Google Alerts of photos.

Face.com utilizes facial recognition technology to automatically and continuously scan newly uploaded photos within a user’s social network. Users are then alerted via Facebook notification, email or both when their face is found in a photo, even if it is not tagged. This puts power back in the hands of Facebook users, allowing them to be the first to take action to hide (or share) embarrassing photos.

The Face Alerts feature is available via Photo Tagger, a recently launched free application that lets users automatically tag photos in bulk to maximizing sharing capabilities. Once a user selects an album (either their own or a friends’), Photo Tagger scans the photos, batches subjects into groups and suggests tags that can be quickly accepted or edited. Details are below.
