Title: FINGERPRINT RECOGNITION METHOD AND DEVICE
Abstract:
Fingerprint recognition method and device. The fingerprint recognition method comprises: acquiring a fingerprint image, and extracting feature information about the fingerprint image (S101); obtaining current application environment information, and obtaining a feature threshold value corresponding to a fingerprint verification security level according to the current application environment information (S102); and comparing the extracted feature information with pre-stored verification feature information, wherein if a comparison result reaches the corresponding feature threshold value, fingerprint recognition succeeds, and if the comparison result fails to reach the corresponding feature threshold value, fingerprint recognition fails (S103). By obtaining current application environment information, obtaining a feature threshold value corresponding to a fingerprint verification security level according to the current application environment information, and then performing fingerprint recognition according to the extracted feature information and the corresponding feature threshold value, a fingerprint recognition process can be completed according to the feature threshold value corresponding to the fingerprint verification security level, so as to improve the fingerprint recognition rate.
