The app helps users find Facebook photos of themselves, their friends, and particular places, and collects these together for private viewing or sharing. It does this by attempting to recognize who appears in them based on facial features, and also takes into account the date, time, and location where the photos were taken.
The U.S. and international versions of the company's photo-centric app use facial recognition technology to identify people in Facebook photos, but the feature ran afoul of privacy laws and regulations in Europe and Canada.
To get around the ban, the new modified version has been stripped of facial recognition technology and instead groups together multiple photos that "appear to include the same face", according to the social media company (via TechCrunch). It does this by relying on a less accurate form of technology that uses object recognition to analyze the distance between a person's eyes and ears.
Moments also integrates with Facebook and Messenger apps, where users are alerted to the fact that their friends have shared photos featuring them.
Moments is a free app for iPhone and iPad available for download in the App Store. [Direct Link]
