Claim One:
1. A computer-implemented method for detecting facial liveliness, comprising: 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.
