As a high security region, prison door’s control and management are especially important. Any accident, will give the prison’s social order brought enormous pressure, even the serious consequences. But the prison as a small society, including prison room, living area, labor workshop, clinic, teaching building, the brig, duty room, dining room, bathroom, playground and other different regions. In any case guard in place, along with scenes of crime, crime increases ceaselessly, simply to card, fingerprint recognition system of prison access control systems exist hidden trouble and vulnerability, the prison had to put a lot of manpower and resources to strengthen the management of access control, including security guards to patrol, guards, such as video surveillance.With the social progress and the ways for effective automatic identity authentication is the urgent demand, biometric recognition technology in the recent decades has been rapid development. Biological characteristics as an inherent attributes, which have very strong stability and individual difference, is becoming the automatic identification of the optimal basis. Face recognition as a biological feature, because of its direct, friendly, convenient features, has been widely studied and applied. So the use of advanced face recognition technology, aiming at the high security level prison unit out of prison, face recognition access control solutions, to effectively control the import and staff’s true identity, has greatly significance.In year2010, in accordance with provision of the Ministry of Justice and Provincial Bureau of Prisons, Shandong Province Prison improves the security system named "Four anti-integration". Prison access control system based on functional requirements is divided into six systems, including:security systems, isolation systems, barricades, surveillance systems, identification systems, alarm systems. The recognition system is responsible to verify and confirm personal information, ensure eligible walkways, to prevent the officers trailing by, stamp out illegal through. In prison access control system, the core that system operating normally is combination of software and hardware, while data synchronization is the major problem in the prison access control system, and face recognition function is the characteristics of the access control system.This paper firstly analyzes the prison structure as well as for access control management system requirements, system includes face recognition module, and according to the access control management system dispersed in various is not conducive to the unified management of the situation, put forward a distributed control and centralized management solutions, through a XML based on the initial configuration module, according to the need of automatic configuration of control system parameter, so the system can adapt to different environments; in addition, detailed data on face recognition access control hardware, hardware and database in the transfer case, elaborated system in data synchronization problems, and proposed to the database as the center of the solutions, to effectively solve the synchronization problem, but also for the distributed access control and centralized management the implementation of solutions provide the basis.In addition, according to the needs of the prison guard system open display process presents a set of multi thread program, integration of face recognition device, using a real-time image acquisition, the staff more convenient monitoring go into the case.The prison access control system based on the MFC multi-document interface, using a number of advanced technologies, and the system is easy to operating, suitable for indoor and outdoor face recognition. Compared with the other products on the market, the prison access control system has a huge advantage.
