Abstract

The invention discloses a user biological characteristic database updating method and device. The user biological characteristic database updating method includes the steps of obtaining a first biological characteristic set of a user; obtaining a second biological characteristic set stored in a biological characteristic database by the user; combining the first biological characteristic set with the second biological characteristic set to obtain a third biological characteristic set, wherein the third biological characteristic set is the combination of the first biological characteristic set and the second biological characteristic set; updating the second biological characteristic set stored in the biological characteristic database by the user to be the third biological characteristic set. By the user biological characteristic database updating method and device, biological characteristic data in the biological characteristic database are updated frequently, and the problem that due to influence of temperature, light, biological characteristic image obtaining angles, distance and other factors, the matching ratio is reduced is solved.

Description

technical field [0001] The invention relates to biometric identification technology, in particular to a method and device for updating a user biometric database. Background technique [0002] Due to the characteristics of stability, uniqueness and convenience of biometric features, biometric technology is used as a means of identity verification to gradually replace traditional identification methods such as keys and passwords. Biometric technology refers to the technology of using some biological characteristics of the human body, such as face, iris, fingerprint, palm print, hand shape, etc., to carry out identification technology, which mainly includes: collecting images, extracting biometric information from the collected images, Then the extracted feature information is matched with all or part of the pre-registered feature information in the database, and the authenticated person is authenticated according to the matching result. [0003] In the existing biometric iden...
