Abstract

The invention discloses a finger vein recognizing system which belongs to the technical field of biometric identification. The invention further discloses equipment which comprises a finger vein image collecting device, an image processing device and an image recognizing and storing device. The image collecting device is connected with the image processing device through a USB interface, and the image processing device is connected with the mage recognizing and storing device through the USB interface. The finger vein recognizing system comprises two modes: an authentication mode and a recognition mode, wherein, the authentication mode is used for verifying whether a person to be verified is a designated person or not, that is, a user first selects a corresponding user number when the system verification is performed; after finger vein images of the person to be verified are collected, a comparison is made between the finger vein images and the template which is stored in a database and corresponds to the user number, so that whether the user is valid or not can be determined; the recognition mode is used for verifying which registered person the person to be verified is, that is, a comparison is made between finger vein image characteristics of the user and the template of the user in the database; and then a template number with the greatest similarity is found, so as to determine the identity of the person to be verified.

Description

Technical field [0001] The invention relates to a finger vein recognition system, which belongs to the technical field of biological feature recognition. Background technique [0002] With the rapid development of information technology, secure computer systems and electronic transaction processing have become more and more important. Nowadays, passwords and password technologies are widely used in the fields of e-commerce and computer security. However, various security systems based on passwords and passwords cannot protect passwords and passwords from being used by illegal users. [0003] More and more people are considering biometric identification, that is, using some of the human body's own characteristics that vary from person to person to verify identity to obtain a higher level of security certification. However, the existing biometric recognition technologies, such as human faces, iris, fingerprints, and palm prints, are very easy to be imitated. In addition, although h...
