Abstract

The invention relates to a fingerprint registration method and device and a fingerprint verification method and device. The fingerprint registration method comprises the following steps: acquiring a fingerprint to be registered; generating a registration fingerprint template according to the fingerprint to be registered; performing abstract operation on the registered fingerprint template to obtain a first hash value; wherein the first hash value is used for verifying that the fingerprint template for fingerprint verification is a registered fingerprint template during fingerprint verification; storing the registered fingerprint template; and sending the first hash value to a main control unit for storage. Abstract operation can be performed on the registered fingerprint template to obtainthe first hash value.According to the invention, the first hash value is stored in the main control unit, and when fingerprint verification needs to be carried out, whether the fingerprint template of the comparison fingerprint is the registered fingerprint template or not needs to be verified in addition to the comparison fingerprint, so that dual verification is realized, the fingerprint template is prevented from being replaced, and the safety of fingerprint verification is improved.

Description

technical field [0001] The present application relates to the technical field of fingerprint identification, in particular to a fingerprint registration method, a fingerprint verification method and a device. Background technique [0002] At present, fingerprint recognition has been widely used in many fields, and various identity authentication devices are embedded with fingerprint recognition modules to facilitate user identity authentication. For example, fingerprint time card machine, fingerprint access control system, fingerprint digital certificate, etc. [0003] A fingerprint authentication device generally includes a main control unit, a fingerprint unit, other functional units, and firmware codes built into each unit. Fingerprint authentication is realized through the fingerprint entry and comparison functions of the fingerprint unit. The main components of this fingerprint unit include a fingerprint algorithm chip, a fingerprint sensor and peripheral circuits. T...
