Embodiment Construction

[0023] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] figure 1 It is a flowchart of a fingerprint template update method provided by an embodiment of the present invention, refer to figure 1 , The method includes:

[0025] Step 101: When the fingerprint characteristics of the user are collected, detect whether there is a fingerprint template matching the fingerprint characteristics of the user in the fingerprint template library.

[0026] When there is no fingerprint template matching the fingerprint feature of the user in the fingerprint template library, step 102 can be executed; when the fingerprint template matching the fingerprint feature of the user exists in the fingerprint template library, step 108 can be executed.

[0027] In the embodiment of the present invention, at least one finge...

Abstract

The invention discloses a method and device for updating a fingerprint template, belonging to the technical field of information processing. The method includes: when there is no fingerprint template matching the user's fingerprint feature in the fingerprint template library, using the user's fingerprint feature to generate a candidate fingerprint template, and recording the candidate fingerprint template in the candidate template library. When there is a candidate fingerprint template whose similarity with the fingerprint template in the fingerprint template library is greater than a preset threshold in the candidate template library, the fingerprint template can be updated according to the candidate fingerprint template. The method provided by the invention can continuously update the fingerprint template during the fingerprint verification process of the user, thus improving the precision of the fingerprint template and further improving the accuracy rate of fingerprint verification.

Description

Technical field [0001] The present invention relates to the field of information processing technology, in particular to a method and device for updating a fingerprint template. Background technique [0002] With the rapid development of biometric technology, more and more devices have begun to use fingerprint sensors to verify the identity of users. The fingerprint sensor can collect the fingerprint features of the same finger of the user multiple times in advance, and generate a fingerprint template based on the fingerprint features obtained through the multiple collections. [0003] In the related art, when the fingerprint sensor detects that the newly collected user fingerprint feature matches a pre-stored fingerprint template, the verification can be confirmed; when the fingerprint sensor detects that the newly collected user fingerprint feature matches the pre-stored fingerprint When none of the templates match, the verification failure can be confirmed, and the newly collec...
