US Patent 11030291 Methods and systems for user authentication

A user device, such as a smartphone or laptop, may be password (passphrase) protected. The user device may combine biometric input analysis, such as facial recognition, with viseme analysis to authenticate a user attempting to use a password (passphrase) to access the user device. Secure authentication on methods and systems are described that account for variations in how, based on the user's emotion (e.g., mood, temperament, unique pronunciation, etc . . . ), a password (passphrase) may be presented to the user device.
