Title: FINGERPRINT VERIFICATION METHOD, FINGERPRINT VERIFICATION DEVICE AND TERMINAL
Abstract:
Provided in the present invention are a fingerprint verification method, fingerprint verification device and terminal. The fingerprint verification method comprises: receiving at least two fingerprint information; determining a similarity between each of the at least two fingerprint information and preset fingerprint information; calculating a comprehensive numerical value of fingerprint superimposition of the at least two fingerprint information according to a similarity between a preset weight of each fingerprint information and the preset fingerprint information and a preset calculation formula for fingerprint superimposition; determining whether the comprehensive numerical value of fingerprint superimposition achieves a preset comprehensive numerical value; and determining whether the fingerprint verification is successful according to the determination result. The technical solution overcomes the defects of the current fingerprint verification function including a low number of collected fingerprints, the singleness of the determination method and high possibility of false identification. Further, increasing the number of fingerprints improves security of fingerprint verification, and determining whether the verification is successful according to the comprehensive value of the similarities can also avoid situations such as identification failures resulted from some objective causes such as stains on the finger, therefore better satisfying actual requirements of the user.
