Abstract

An entrance guard system based on palm print character comprises palm print collection unit, storage unit, on- site programmable gate array appliance, global mobile communication system, crystal display screen and door lock control unit. It features that on-site programmable gate array appliance is utilized to prepare an embedded system block with independent outline to make entrance system more integration, more modularization and more easy to install.

Description

technical field [0001] The invention relates to an access control system based on palmprint features, which belongs to the field of electromechanical technology. Background technique [0002] The development of social informatization, digitalization, and networking has brought great convenience to people's daily production and life, but at the same time, the security of the information society is facing more and more severe challenges. Traditional information security systems based on passwords or passwords are far from meeting people's needs, and biometric identification technology is increasingly being used in telecommunications, finance, transportation and other fields. The development of identity authentication based on biometric identification technology is closely related to the public's own interests. It is the demand of social and economic development in this century and a strategic demand involving national interests. Palmprint recognition is a new biometric techno...
