Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0043] see figure 1 As shown, the embodiment of the present invention provides a method for unlocking a terminal based on biometric identification, including a registration process and an authentication process, specifically including the following steps:

[0044] S1: When the user registers, collect one or more biometric information of the user to form a biometric set;

[0045] S2: Generate identification data according to the set of biometric features and terminal device identification information;

[0046] S3: When the user to be verified unlocks the terminal, collect one or more biometric information of the user to be verified to form a biometric set to be verified;

[0047] S4: Generate data to be verified according to the biometric set to be verified and the identification information of the terminal device;

[0048] S5: Compare the i...

Abstract

The invention discloses a terminal unlocking method and system based on biological feature recognition, and relates to the technical field of biological recognition, and the method comprises the steps: collecting one or more types of biological feature information of a user during the registration of the user, and forming a biological feature set; generating identification data according to the biological characteristic set and the terminal equipment identification information; when the to-be-verified user performs terminal unlocking, collecting one or more pieces of biological characteristicinformation of the to-be-verified user to form a to-be-verified biological characteristic set; generating to-be-verified data according to the to-be-verified biological feature set and the terminal equipment identification information; and comparing the identification data with the to-be-verified data, if comparison succeeds, unlocking the terminal, and otherwise, returning to the screen locking interface. According to the invention, during registration and unlocking, the biological characteristic information is not stored, so that leakage of the biological characteristic information of the user is avoided.

Description

technical field [0001] The present invention relates to the technical field of biometric identification, in particular to a terminal unlocking method and system based on biometric identification. Background technique [0002] At present, the traditional biometric identification method, in the registration process, collects the user's biometric information, such as fingerprints, faces, iris, finger veins, etc., and uses a specific algorithm to extract the feature sequence of the user's biometric information as a biometric template feature. Sequence, stored in the system, used for user authentication. [0003] In the process of terminal device unlocking and authentication, it is also necessary to collect the user's corresponding biometric information, such as fingerprints, faces, iris, finger veins, etc., and use the same processing method as in registration to combine the sample feature sequence with the template Compare the characteristic sequences to obtain the result of i...
