Fingerprint Recognition Technology Management System, Named The Offender Fingerprint

With the development of our society, The traditional security systems which based mainly on token or password, such as key, password, ID card and even IC card, have fallen behind the needs of economic activity and social security, This is because that they would be forgetable, falsifiable, stolen or decodable. With the development of electronic computer and information technology, the identification technology using biometric, automatic identification an individual by using certain physiological or behavioral characteristics associated with the person, have drawn more attention, such as face,fingerprint,iris,DNA and voice etc. Because of the In invariability and uniqueness of the fingerprints, fingerprint recognition technique is superior to others and is becoming the most reliable biometric recognition technique, widely used in forensic, police and other security system recently。AFIS (Automated Fingerprint Identification System) is applied in daily life more and more with the appearance of cheap collector and the effective algorithms. AFIS is becoming the research center of academic and commerce.In this paper, we have studies and analysed Fingerprint recognition,Automatic fingerprint identification system and fingerprint identification alogthium at first. The alogthium is mainly composed of three sections, which are fingerprint preprocessing (includes gray_level image filtering,binarization and thinning),feature extraction and fingerprint matching. Market investigate about fingerprint recognition product is do. the seconds programming uses optics fingerprint collection apparatus in DP company and SDK software pack in zhongkong company. the Individual Identity-Authentication scheme is designed to meet the requirement of the jail, which was based on fingerprint identification technology, we estblished antomatic fingerprint identification system (AFIS) -the registration management system by fingerprint to verify prizoners' identity for jail. It includes the designs of system hardware and software. Identification software, the core of our AFIS consists of fingerprint image register and fingerprint verification module.The results show that the design of the fingerprint identification system is reasonable and realizable. It would have a wide range of applications and a bright future.
