Finger vein and fingerprint hybrid identity authentication device and method

Abstract

The invention discloses a finger vein and fingerprint hybrid identity authentication device and method. In a same structure, two independent groups of infrared spot lights are utilized to extract vein information and fingerprint information of a finger respectively, the structure is simple, and the operation is convenient; the complementation of the two types of biological identification modes of finger vein and fingerprint is realized, so that the authentication accuracy is higher, and scope of application is wider; due to the arrangement of an isolation board and two rows of infrared spot light groups, light irradiated to a verifying finger can be adequate and irradiated accurately; moreover, image interference to vein information and fingerprint images is reduced, so that the acquisition accuracy and success rate are improved, and a guarantee is provided for follow-up certification; comparison authentication is carried out in an intelligent terminal, so that equipment does not need to store feature information or perform comparison authentication, the function is simpler, and the component is smaller; and due to the adoption of low-energy design, the finger vein and fingerprint hybrid identity authentication device is connected with other intelligent equipment via a USB for information exchange, and is powered by the USB directly, so that no external power supply is needed.

Description

technical field [0001] The invention relates to the technical field of biological feature identification, in particular to a finger vein plus fingerprint hybrid identity authentication device and method. Background technique [0002] In recent years, as people have increasingly strict security requirements for identity documents, personal items, internal networks, building passages, the Internet and even e-commerce, the demand for identity authentication technology has become more and more urgent. As the most secure and convenient identification method at present, biometric identification technology has received great attention and has been greatly developed under this emphasis. At present, the widely used biometric methods of human body mainly include fingerprint, iris, face recognition, finger vein and so on. [0003] Although there are many biometric identification methods, there are more or less disadvantages in a single biometric identification method, such as fingerpr...

AI Technical Summary

Problems solved by technology

[0003] Although there are many biometric identification methods, there are more or less shortcomings in a single biometric identification method, such as fingerprints can be copied, iris recognition takes a long time, face recognition accuracy is low, finger vein recognition is affected by light, etc.

In practical applications, a single biometric method often cannot meet the needs

[0004] Although a variety of biometric identification methods have been proposed at present, the existing technology is only a simple superposition of multiple biometric identification methods, which requires structural separation. The structure is complex, and the light is insufficient, and the extracted biometric features are inaccurate, resulting in authentication accuracy. not tall
