Title: LIVING FINGERPRINT RECOGNITION METHOD AND DEVICE
Abstract:
A living fingerprint recognition method and device. The living fingerprint recognition method comprises: extracting an image feature of a real-time fingerprint from a collected real-time fingerprint image (S11); comparing the image feature of the real-time fingerprint with stored fingerprint image features of a living body and a non-living body, so as to generate the credibility of the real-time fingerprint (S12); and determining, according to the value of the credibility of the real-time fingerprint, whether the real-time fingerprint is collected from the living body (S13). In the living fingerprint recognition method, by comparing an image feature of a real-time fingerprint with stored fingerprint image features of a living body and a non-living body, the credibility is generated to identify whether the obtained real-time fingerprint comes from the living body or the non-living body, thereby effectively filtering out real-time fingerprint data collected from the non-living body; the method is used in the fingerprint template update and fingerprint validity authentication, thereby improving the security of fingerprint recognition; and the method does not require any additional hardware device, thereby reducing costs.
