Finger vein authentication system

Abstract

The invention discloses a finger vein authentication system. The finger vein authentication system comprises a finger vein image acquisition device (1), an image processing module (2), a registering template storage module (3) and a control management module (4), wherein the control management module (4) sends out a reading image requirement signal to the finger vein image acquisition device (1); the finger vein image acquisition device (1) acquires a finger vein image signal according to the reading image requirement and sends the finger vein image signal to the image processing module (2); and the image processing module (2) pre-processes the finger vein image signal to obtain finger vein characteristics, transmits the finger vein characteristics to the registering template storage module (3) for storage and registration, or compares the finger vein characteristics with the finger vein characteristics which are stored and registered by the registering template storage module (3) for authentication. The system overcomes the defects that the conventional biological special identification technology is easy to copy and easy to damage, has a small size, and is high in authentication speed and high in accuracy.

Description

technical field [0001] The invention belongs to the technical field of identity recognition and authentication by using human biological characteristics, and specifically refers to a system for collecting finger vein images for authentication. Background technique [0002] With the advent of informatization, more and more people pay attention to the security and confidentiality of information. The rich physiological characteristics of the human body make biometric identification technology an important means in the field of identity authentication. [0003] Biometric identification technology refers to a technology that uses human physiological characteristics for identity authentication. Different from traditional identity authentication methods (ID cards, work permits, smart cards and passwords, etc.), it uses the information carried by the human body itself and does not rely on other objects, so there is no inconvenience in carrying, easy to lose, or due to excessive or ...

AI Technical Summary

Problems solved by technology

However, fingerprint identification also has its own disadvantages: (1) The fingerprint has the problem of wear and tear, which makes it impossible to authenticate; (2) Every time the fingerprint is used, the fingerprint of the user will be left on the fingerprint collector, so there is a possibility of being used to copy the fingerprint ; (3) The impact of the environment, such as wet fingers will affect the authentication results

Domestic related research is mainly concentrated in research institutes and university laboratories. At present, there is no finger vein authentication product based on independent intellectual property rights that has been launched on the market.
