Finger vein identity authentication apparatus and method

Abstract

The invention discloses a finger vein identity authentication apparatus and method. The finger vein identity authentication apparatus comprises separating boards, infrared lamp groups and a concentrating assembly, wherein the separating boards are arranged on the two sides of a guiding slot for placing a verified finger, and used for blocking infrared light from the outside; the infrared lamp groups are symmetrically arranged in the separating boards on the two sides of a finger bearing platform, and used for providing a light source; and the concentrating assembly is positioned in front of the infrared lamp groups, and used for adjusting the irradiating angle of the light rays of the infrared lamp groups to the verified finger. According to the finger vein identity authentication method, a windows starting up login management program is utilized for realizing binding of the starting up login and the finger vein identity authentication apparatus; and then the finger vein identity authentication for the windows starting up login is realized through a logon procedure and an authentication procedure. The precision and success rate of finger vein image collection are effectively improved, so that the security of individual finger vein feature information is ensured and a false authentication phenomenon is completely eradicated; and in addition, low power consumption design is adopted and an external power supply is not required, so that the finger vein identity authentication apparatus and method are high in actual practical value.

Description

technical field [0001] The invention relates to the technical field of biological feature identification, in particular to a finger vein 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 human biometric identification methods mainly include fingerprint, iris, face recognition, etc., all of which are based on the collection of human body surface characteristics for identification and authentication. They are all visually visible to the human body, and are easy to obtain and copy....

Problems solved by technology

[0003] However, the collection of finger vein images has high requirements on light. When the current finger vein recognition technology collects finger vein images through cameras, it is vulnerable to the influence of external ambient light, insufficient light, and the light cannot be accurately aligned with the information to be collected. The problem of fingers often occurs that finger vein recognition cannot be performed, resulting in low efficiency of finger vein recognition; in addition, the current finger vein recognition device generally only has the function of extracting finger vein information, and the authentication is performed by an electronic device connected to the finger vein recognition device. equipment, which also causes the inconvenience of identity authentication
