Problems solved by technology

[0004] The existing method for updating the biometric template is likely to use the attacker’s biometric image to update the biometric template when the attacker’s biometric image is compared with the biometric template, resulting in the biometric system’s defense against attacks. The control performance is poor, and will lead to a high false pass rate in the subsequent identity authentication process

Abstract

The embodiment of the present application discloses a method, device and electronic device for updating a biometric template. The method includes: determining the first similarity between the biometric template of the first user and the first biometric image set, the first biometric The set of images includes at least one biometric template of the second user; determining a second degree of similarity between the first set of biometric images of a preliminary biometric image that has successfully matched the biometric template of the first user and the first set of biometric images A matched biometric image: determining whether to use the preliminary biometric image to update the biometric template of the first user according to the first similarity degree and the second similarity degree.

Description

technical field [0001] The present application relates to the field of biometric identification, and more specifically relates to a method, device and electronic device for updating a biometric template. Background technique [0002] When the biometric identification system authenticates the user, it will collect the biometric image of the person to be authenticated, compare the collected biometric image with the pre-stored biometric template, and judge according to the result of the comparison and the corresponding strategy Whether the authentication is passed. [0003] As time changes, there may be differences between the user's real biometrics and the biometrics corresponding to the biometric template. In order to ensure that the biometric template can reflect the latest biometrics of the authority owner to the greatest extent, the biometric identification system needs to update the biometric template. to update. [0004] The existing method for updating the biometric t...
