This disclosure describes techniques to prevent unauthorized access to information via a facial recognition interface. With user permission, a live video of the user attempting to access the information is obtained via a camera to perform facial recognition and determine the presence of the user. The user is instructed to dictate a randomly generated passphrase while facing the camera. Lip reading techniques are applied to validate the dictation of the randomly generated passphrase. Access to the information is granted only upon successful validation.
