Abstract

The invention provides a fingerprint verification method, a fingerprint verification device and a terminal. The fingerprint verification method comprises the steps that at least two pieces of fingerprint information is received; similarity of each piece of fingerprint information in the at least two pieces of fingerprint information and the preset fingerprint information is determined; the fingerprint superposition comprehensive value of the at least two pieces of fingerprint information is calculated according to similarity of the preset weight of each piece of fingerprint information and the preset fingerprint information and the preset fingerprint superposition algorithm formula; whether the fingerprint superposition comprehensive value reaches the preset comprehensive value is judged; and passing of fingerprint verification is determined according to the judgment result. With application of the technical scheme, defects of existing fingerprint verification functions that the number of fingerprint acquisition is low, the discrimination method is simple and mistaken identification is liable to occur can be improved. Security of fingerprint verification can be enhanced by increasing the number of fingerprints, and then passing of verification is determined according to the comprehensive value of similarity. Besides, the condition that the fingerprints cannot be identified due to dirty marks on the fingers and other objective reasons can also be avoided so that the fingerprint verification method is suitable for the actual requirements of users further.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a fingerprint verification method, a fingerprint verification device and a terminal. Background technique [0002] The current fingerprint identification scheme is to first collect one or more single fingerprints of the user, and then compare one or more single fingerprints with the preset one or a pair of preset single fingerprints, and judge whether the user is for legitimate users. [0003] However, this fingerprint identification scheme needs to collect a small number of fingerprints, and the identification method is single, and when there are stains, sweat stains on the hands of legitimate users, or when the hands are shed, the phenomenon of false identification will occur. [0004] Therefore, there is a need for a new technical solution, which can improve the defects of the fingerprint verification function, such as the small number of fingerprints collected, the...
