Problems solved by technology

However, in the above-mentioned fingerprint authentication, the security logic of the terminal system is not strong, that is, no matter in any application environment, it is necessary to compare all the characteristic data with the sample characteristic data, resulting in a huge amount of data calculation, which consumes a lot of time. A large number of processor, battery and memory resources, resulting in waste of resources

Abstract

The embodiment of the invention discloses a fingerprint authentication method and a terminal. The fingerprint authentication method includes: acquiring an application environment parameter of the terminal if a fingerprint image input by a user is received; determining the safety class of a current authentication according to the application environment parameter; determining the matching amount of the safety class of the current authentication according to a corresponding relationship between a preset safety class and the fingerprint characteristic data matching amount; extracting characteristic data of the fingerprint image input by the user; and comparing the extracted characteristic data and pre-stored sample characteristic data according to the determined matching amount so as to perform authentication. The embodiment of the invention also discloses the terminal. The fingerprint authentication method can intelligently adjust the fingerprint characteristic data matching amount according to the application environment parameter of the terminal, and then decrease the power consumption of a terminal system, and reduce the resource waste.

Description

Technical field [0001] The invention relates to the technical field of fingerprint authentication, in particular to a fingerprint authentication method and terminal. Background technique [0002] Fingerprint authentication refers to the uneven lines on the front skin of the finger end, which contains a lot of information. The lines of these skins are different in patterns, break points and intersections. They are called "features" in information processing, and these features are unique and permanent, and can associate a person with his fingerprints. , By comparing fingerprint features with pre-saved fingerprint features, you can verify their true identity. At present, fingerprint authentication is mainly used in the field of terminal screen unlocking and safe consumption. For example, for the security of the terminal, it is usually necessary to set a fingerprint authentication password, and by reading the user’s fingerprint characteristic data, and comparing the characteristic...
