Network finger vein access control system and control method thereof

Abstract

The invention discloses a network finger vein access control system and a control method of the network finger vein access control system. The finger vein recognition speed can be improved, the recognition terminal structure can be simplified, the use convenience and reliability of the system are improved, and the safety of vein sample protection is improved. The network finger vein access control system comprises a management computer, a finger vein characteristic collector, image processors, access controllers, a converter and finger vein recognition terminals; the finger vein characteristic collector is connected with the management computer; each image processor is connected with the plurality of finger vein recognition terminals through the converter, and connected with a plurality of controlled doors through one access controller; the finger vein recognition terminals correspond to the controlled doors one by one; the image processors carry out vein characteristic recognition and comparison on the images collected by the finger vein recognition terminals; the access controllers carry out permission validation on the information of a requester, and carry out the opening operation according to the validation result.

Description

technical field [0001] The invention relates to a network-type finger vein access control system and a control method thereof, which belong to the technical field of biological feature identification and are used in security systems. Background technique [0002] Finger vein recognition technology is a new type of biometric recognition technology, which uses the different distribution of finger vein lines to achieve identity verification and protect the target. [0003] At present, the finger vein access control identification terminal has the functions of image acquisition, identification and storage. The image comparison is carried out in the identification terminal, and each terminal needs to have image processing function, which makes the terminal cost relatively high; the vein feature information is not easy to maintain, and If the terminal is lost, the vein feature information will also be lost. Contents of the invention [0004] In view of this, the present inventi...
