Title: OPTICAL FINGERPRINT IDENTIFICATION METHOD, AND RELATED PRODUCT
Abstract:
Disclosed in embodiments of the present invention are an optical fingerprint identification method, and related product. The method comprises: upon a touch display screen detecting a touch operation of a user with respect to a first region, a mobile terminal controlling an optical fingerprint identification module to acquire fingerprint data of the user, and sending the fingerprint data to an AP; the mobile terminal employing, by means of the AP, pre-acquired noise data to perform denoising on the fingerprint data, so as to obtain repaired fingerprint data, wherein the noise data is acquired by the optical fingerprint identification module in advance when no touch operation occurs in the first region; and the mobile terminal determining, by means of the AP, whether the repaired fingerprint data matches pre-stored fingerprint template data, and if so, then authenticating the fingerprint. The embodiments of the invention improve a success rate for fingerprint matching.
