Computer regional network type fingerprint entrance guard system

Abstract

A computer LAN-type fingerprint-base entrance guard system is composed of hardware and software. Its hardware is composed of fingerprint processing server, multiple entrance guard terminals and network communication equipment. A LAN is composed of said fingerprint processing server and multiple entrance guard terminals. The fingerprint data is acquired, compressed and encrypted by the entrance guard terminals and then transmitted to the fingerprint processing server, where original data is restored by decompression and decryption and compared with the fingerprint data stored in database. The result is transmitted to the entrance guard terminal to open or lock door.

Description

1. Technical field: [0001] The invention relates to a computer local area network fingerprint access control system. 2. Background technology: [0002] Fingerprint access control is a security product that began to appear at the end of the last century. It relies on computer technology and uses fingerprint comparison algorithms to identify individuals based on the uniqueness and invariance of fingerprints. It is an access control product that recognizes people but not objects. Compared with the previous methods of identifying objects and opening doors with keys, passwords, and IC cards, fingerprint access control is undoubtedly a qualitative leap, with stronger security and better convenience. It will be a substitute for inductive IC card access control. [0003] In the past, fingerprint access control used an embedded fingerprint identification system that integrated a microcomputer and a fingerprint collector. This fingerprint identification system, which uses a microcomp...

Problems solved by technology

[0003] In the past, fingerprint access control used an embedded fingerprint identification system that integrated a microcomputer and a fingerprint collector. This fingerprint identification system, which uses a microcomputer as the software and hardware operating platform, has good networking capabilities and is easy to integrate into the system. and centralized management, but the operating platform has a large amount of software and hardware redundancy, resulting in high software and hardware costs of the system, because the fingerprint recognition system using a microcomputer as the software and hardware operating platform independently completes the collection, compression, storage, and processing of fingerprint data. A complete set of tasks such as comparison and identification, control output and establishment of fingerprint database have higher requirements on software and hardware.

[0004] In addition, even though the fingerprint identification system with microcomputer as the operating platform of software and hardware has a good networking function, they only complete the mutual communication function through the RS232 serial port, so the communication distance is relatively short, generally only about 10 meters , which limits its scope of application
