METHOD AND APPARATUS EMPLOYING AUDIO AND VIDEO DATA FROM AN INDIVIDUAL FOR AUTHENTICATION PURPOSES

摘要

A method and apparatus is provided for determining the authenticity of an individual. In accordance with the method, audio and video data of the individual speaking at least one selected phrase is obtained. Identifying audio features and video features are then extracted from the audio data and the video data, respectively. A feature vector is formed which incorporates both the audio features and the video features. The feature vector is compared to a stored feature vector of a validated user speaking the same selected phrase. The individual is authenticated if the feature vector and the stored feature vector form a match within a prescribed threshold.
