Abstract:
Methods, systems, and computer-readable storage mediums for detecting facial liveliness are provided. Implementations include actions of processing a facial image of a subject to determine a corneal reflection of an illuminator adjacent to the subject, the facial image being captured at a time point, determining an expected corneal reflection of the illuminator based on an illumination of the illuminator at the time point, comparing the determined corneal reflection of the illuminator to the expected corneal reflection of the illuminator to obtain a comparison result, and determining facial liveliness of the subject based on the comparison result.

Claim (Index 21):
A method of detecting facial liveliness by a mobile phone, the method comprising:\n determining that a subject chooses to use liveliness verification for facial biometric authentication; activating an illuminator to illuminate, the illuminator being adjacent to the subject; capturing, by a camera of the mobile phone, first and second images associated with a face of the subject at first and second sequential time points, respectively, each of the first and second images including a representation of a respective corneal region of the subject that has a respective corneal reflection of the illuminator; processing the first and second images to determine facial biometric data of the subject and respective first and second corneal reflections of the illuminator; determining a corneal reflection change of the illuminator based on the determined first and second corneal reflections; comparing a correlation between the determined corneal reflection change of the illuminator and an illumination change of the illuminator associated with the first and second sequential time points to a threshold determined based on a varying context-dependent requirement; determining facial liveliness of the subject based on a result of the comparison; and transmitting, to a computing device at an identity provider, an authentication request of the subject for accessing an account managed by a relying party associated with an entity different from the identity provider, the authentication request including:\n the facial biometric data of the subject for proof of identity of the subject, and \n the determined facial liveliness of the subject for verification that the transmitted facial biometric data of the subject is fresh and live.
