Here’s how it works: When you log into Photo Finder, the app uses its facial recognition technology to search for untagged pictures of you or your friends throughout Facebook by scanning all the public photos in your network. When it finds photos, it suggests tags based strictly on the faces identified. This could lead to less embarrassing pictures floating about without your knowledge. So far, it seems to work pretty well.
Face.com, based in Tel Aviv and New York, apparently built the Facebook app as a technology demonstration. The company is angel funded and currently raising an A round. While it’s still in closed beta, the first 100 Inside Facebook users who click on this link will be able to try the app out.
