Fingerprint dynamic password ID authentication device and the implementation method thereof

Abstract

The invention aims to provide a fingerprint dynamic password ID authentication device and the implementation method thereof, which can effectively address the problems of equipment steal, insufficient cryptographic strength, inreversible generated dynamic passwords, lower security, great system consumption and the like in the ID authentication field. The equipment related to by the invention comprises a fingerprint chip, a fingerprint sensor, a dynamic password chip, a display, a storage medium, a power supply, a recharging interface and a control circuit; wherein, the control circuit is respectively connected with the fingerprint chip, fingerprint sensor, dynamic password chip, display, storage medium, power supply and recharging interface. The fingerprint dynamic password ID authentication device has the advantages that the fingerprint dynamic password ID authentication device can employ double authentications, namely authenticating a user's right to use a device through the user fingerprint and then authenticating the user's right to perform operations on a terminal through a dynamic password generated by the device, to ensure the user authentication device can be only used by the user himself and the authentication information is not stolen, thus sufficiently ensuring the security of the user account and rights.

Description

technical field [0001] The invention relates to identity authentication technology, in particular to a fingerprint type dynamic password identity authentication device and its realization method. Background technique [0002] Identity authentication is the cornerstone of information security, and the diversification of identity authentication technology is the direction of progress in information security technology. Before accessing any system, the user must first verify whether the user's identity is legal through some identity authentication mechanism. After the identity authentication is successful, he can access some resources of the system or perform an operation according to the user's legal identity. In order to improve the security of identity authentication, at present, hardware device-assisted methods are usually used to realize identity authentication, but the problem of hardware device theft is becoming more and more serious, and hardware devices may not be able...
