Facial recognition ID with a twist: Smiles, winks and other facial movements for access

Concurrent Two-Factor Identity Verification requires both one's facial identity and a specific facial motion to gain access. To set it up, a user faces a camera and records a short 1-2 second video of either a unique facial motion or a lip movement from reading a secret phrase. The video is then input into the device, which extracts facial features and the features of the facial motion, storing them for later ID verification.
