Multi-mode biological characteristic authentication device and system

Abstract

The present invention discloses a multi-mode biological characteristic authentication device which is provided with a first fingerprint sensing module, a second fingerprint sensing module, a palm print sensing module, an information receiving unit and a prompting unit. The first fingerprint sensing module is used for acquiring first fingerprint information of an index finger, a middle finger, a ring finger and / or a little finger of a user; the second fingerprint sensing module is used for acquiring fingerprint information of a thumb of the user; the palm print sensing module is used for acquiring palm print information of the user; the information receiving unit is used for receiving the first fingerprint information from the first fingerprint sensing module, the second fingerprint information from the second fingerprint sensing module and the palm print information from the palm print sensing module and determining whether the information is synchronously and correctly acquired; and if the information is synchronously and correctly acquired, correct acquisition prompt information is sent out by the prompting unit. According to the present invention, the identity can be authenticated better; reliability is high; difficulty and complexity in counterfeiting of biological characteristics of a human body are improved; and safety of the system is improved.

Description

technical field [0001] The present invention relates to an identity verification device and system, in particular to a multi-modal biological feature identity verification device and system. Background technique [0002] Human body biometric information is relatively diverse, involving face, fingerprint, palm print, iris, voice, etc. The collection requirements of various biometric information are different, each system is formed, and effective integration is difficult. Various biometric identification technologies have their own advantages and disadvantages. For some special industry applications with high security requirements, the fusion application of several biometric identification technologies is required to further improve the overall security of identity verification. In fields such as financial payment, as well as in various fields that require citizens' biometric identity verification, a single biometric information is easy to be cracked. At present, there is no ...

AI Technical Summary

Problems solved by technology

[0003] The existing equipment for integrated collection of human biometric information has large volume, unstable signal, cumbersome operation, and narrow database range, which still make users complain endlessly. Therefore, an easy-to-carry, easy-to-use, and more complete database is produced. Multimodal biometric authentication devices and systems have also become current problems to be solved
