Abstract

The invention discloses an identification and authentication device based on finger biometric. The device comprises a handle part, a fingerprint collection part, a light source, an image pickup part, a tact switch and a processing part. The processing part is respectively connected with the tact switch, the fingerprint collection part, the light source and the image pickup part. The device is usually in standby state, and a system starts to work when the tact switch is triggered: first, the light source is started to illuminate the position between the knuckle at a proximal interphalangeal joint of a finger and a distal interphalangeal joint of the finger, and the image pick-up part obtains a finger vein image; meanwhile, the fingerprint collection part collects a thumb fingerprint image, then the two images are subject to preprocessing and feature extraction respectively, and matched with the finger vein feature and the fingerprint feature stored in a database; finally, the judgment whether the authentication is successful is obtained by evaluating the similarity thereof. The invention fully utilizes two different biometrics at different cutaneous layers of the finger, can enhance the anti-counterfeiting property, the security and the accuracy of the system.

Description

Technical field

[0001] The present invention relates to the field of biometric identification technology, and in particular to the technology of using finger biometrics for identity authentication. Background technique

[0002] Human vein recognition is the latest biometric technology. The so-called biometric technology is the close combination of computers and high-tech methods such as optics, acoustics, biosensors, and biostatistics, using the inherent physiological characteristics of the human body (such as fingerprints, facial features, etc.). Image, red film, etc.) and behavioral characteristics (such as handwriting, voice, gait, etc.) for personal identification. Since the biological characteristics of the human body have the uniqueness inherent in the human body that cannot be copied, this biological characteristic key cannot be copied, stolen or forgotten. Using biometric recognition technology, people have developed a variety of human biometric systems such as fingerprin...
