Study Of Triple Identity Recognition System Based On RFIC, Fingerprint And Password

Entrance guard system, as well called access controller system, is the digital management apparatus to control the access of the personnel. The familiar sorts of the entrance guard system are password entrance guard system, IC card system, non-contact IC card system, biometric identification system, etc. And the biometric identification entrance guard system includes fingerprint system, iris system, palm print system and voice system and so on.Traditional password input is an insecure way. The card is easily dropped or stolen, as well as the fingerprint has the possibility of being copied, which make sure that single identification entrance guard system has no possibility possessing high security. Basing on detailed investigation and analysis of the technology domain development status inside and outside of the country, this paper bring forward a system scheme combined the technology of RFIC, fingerprint, password input. This scheme used the merits of radio frequency technology, fingerprint identification technology and password input method. It absolutely put an end to the hidden trouble possibly occurred, and improved the secure capability of the system.This system primarily made use of radio frequency recognition technology and fingerprint identification technology. It used embedded ARM apparatus as the center processor, which provided the system with a high response speed. According to the exploitation requirement, this system could choose the way not corresponding with monitor computer and working alone with the requisite information stored in the memory, or the way using monitor computer to achieve the identification of RFIC card, fingerprint or password. It has the characteristics of high response speed, good stability, speICal security, etc. It can satisfy the people's day-increasingly safety requirement and some speICal situation. So, it has a high market prospect.
