Abstract

An identity recognition system includes a target region acquisition module, a photoplethysmography signal conversion module, a biometric characteristic conversion module, a face characteristic acquisition module, and a comparison module. The target region acquisition module is configured to acquire a plurality of target region images from a plurality of face images. The photoplethysmography signalconversion module is configured to generate a photoplethysmography signal according to the target region images. The biometric characteristic conversion module is configured to convert the photoplethysmography signal into a biometric characteristic. The face characteristic acquisition module is configured to acquire a face characteristic from the face images. The comparison module is configured to fuse the face characteristic and the biometric characteristic into a fused characteristic and perform similarity calculation on the fused characteristic and a plurality of fused characteristics stored in a database to determine identity of an identified person. The identity recognition system of the present disclosure has a high-accuracy body identification ability, and can also confirm that theidentified person is a living body instead of a photo.

Description

technical field [0001] The invention relates to an identity identification system and an identity identification method. Background technique [0002] Face recognition is a kind of identity recognition technology for identity recognition by analyzing the shape and position relationship of human face organs. At present, the face image of the person to be recognized can be captured by an image sensor, and the face features can be extracted from the face image. Next, compare the face features with the face features of each face image in the database, so as to determine the identity of the person to be identified according to the comparison result. [0003] However, traditional face recognition cannot tell the difference between a living person and a photo. Taking the face recognition control system as an example, if someone uses the same photo as the face image in the database for face recognition, it is also possible to pass the face recognition control system. [0004] Thi...
