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 2):
A computer-implemented method for detecting facial liveliness, comprising:\n processing, by one or more processors, first and second images associated with a face of a subject to determine first and second corneal reflections of an illuminator adjacent to the subject, the first and second images being captured at first and second sequential time points, respectively; determining, by the one or more processors, a corneal reflection change of the illuminator based on the determined first and second corneal reflections; comparing, by the one or more processors, 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; and determining, by the one or more processors and based on a result of the comparison, facial liveliness of the subject.
