Earlier, it was reported that Facebook was developing a new feature for its own Messenger communications software — face recognition with Face ID to better protect users’ privacy. Now, there have been netizens on Twitter and confirmed the matter. Jane Manchun Wong points out that this feature can be revalidated after a user leaves the app, or at regular intervals.
This feature is also known as “Face ID Lock” (Instagram via MSPU)
@wongmjane speculated that Facebook Messenger would use the phone’s built-in biometric authentication technology to avoid daily shots of the user’s face and upload it to a remote server for comparison.
@alexvoica, Facebook’s technology communications manager, also appeared to confirm the incident, meaning the feature will soon be available.
For privacy-conscious people, biometric authentication unlocks effectively prevent stoic information from friends, family and other unauthorized people.
