High security vena digitalis verification entrance guard system and unlocking method

Abstract

The invention discloses a high security vena digitalis verification entrance guard system and an unlocking method. The high security vena digitalis verification entrance guard system comprises an entrance guard lock, a vena digitalis acquisition module, a local server, a re-verification unlocking module, a prompt module and a rechargeable module, wherein the local server is electrically connected to the vena digitalis acquisition module, the re-verification unlocking module, and the entrance guard lock. According to the present invention, the vena digitalis image verification is used as the first layer verification, and the second secret key generated by re-compilation through the ID card is used as the second layer verification, such that the vena digitalis and the ID card become the separated verification ways, ie., the staff picking the card cannot directly open the entrance guard lock through the single ID card even if the ID card is lost, and the replacement of the card reading of the partial staffs with the card reading of other staffs can be effectively avoided, wherein the partial staffs want to escape from the working attendance check; and the vena digitalis image is used as the first layer verification so as to improve the use security and the reliability of the entrance guard system.

Description

technical field [0001] The invention relates to the technical field of access control security, in particular to a high-security finger vein verification access control system and an unlocking method. Background technique [0002] In the prior art, access control systems often use fingerprints as the verification medium for unlocking access control, and fingerprints are easily copied and stolen by criminals using rubber finger cots, so that the access control system cannot achieve the locking effect. Some access control systems use channels such as ID cards or ID cards as the way to unlock the access control system, but if the ID card or ID card is lost, other personnel who pick up the card can easily steal the ID card or ID card to pass through the access control system. [0003] Therefore, in the application of the access control system with high security performance requirements, it is of great significance to use separate authentication devices and mechanisms and improve...
