Digital identity verification system

Abstract

A digital identity verification system includes a processing unit, a communication unit electrically connected to the processing unit, and a storage unit. The processing unit executes an online identity verification procedure to verify voice data and video data received via the communication unit from a user's computer device and corresponding to a predetermined statement. The processing unit segments the voice data into multiple audio frames according to a predetermined time sequence and extracts multiple corresponding video frames from the video data according to the predetermined time sequence. Identity verification is deemed successful when the signal spectrum of the audio frames matches a set of acoustic spectrograms stored in the storage unit, and the lip features of the video frames match a set of lip features stored in the storage unit.
