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 invention discloses a method and device for updating a biological feature template and electronic equipment. The method comprises the steps of determining first similarity between a biological feature template of a first user and a first biological feature image set, wherein the first biological feature image set comprises biological feature templates of at least one second user; determining second similarity between a reserved biological feature image and the first biological feature image set, wherein the reserved biological feature image is a biological feature image which is successfully matched with the biological feature template of the first user; and determining whether to update the biological feature template of the first user by using the reserved biological feature image or not according to the first similarity and the second similarity.

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...
