Tech companies are seeking out new ways to enable users to easily access their devices and accounts without having to remember a phrase or code. With Google’s facial recognition patent, it appears the corporation has devised its own alternative.

Google’s facial recognition method would require users to make a predetermined facial gesture that would then be scanned and compared to a previously captured photo for authentication. Each time a device asks for identification, the user would have to make a face that includes movement of an eye, eyebrow, mouth area, forehead area or nose.

Suggested gestures range from a “wink” or “eyebrow movement” to a “nose wrinkle” or “tongue protrusion.”

Google’s requirement for a user to make a unique gesture seems to be a new attempt to thwart unauthorized users from accessing devices that don’t belong to them. Google’s patent even notes how some of the techniques could prevent “prevent erroneous authentication caused by spoofing.”

The idea here is that a hacker can fool a computer with a static image. But moving our faces in a very particular way is a unique marker that not even an impostor can fool.
