Facebook just announced and released the app Moments (moments). The new application uses facial recognition software to scan your phone's camera roll.
It will recognize the faces you have as friends on the social network even if you allow it to share the photos. 
How does it work:
The application will scan your phone gallery. Moms will locate the faces of your Facebook friends, and then notify them of a private exchange.
If he discovers many photos of a friend, you can send them all together as a package.
Photos are stored in a private album that only you and the recipient can see.
If the app recognizes more than one person, it will let you know and ask you to share the photos in a group.
Moments has just been released for Android and iOS.
