Personnel Information Acquisition System(PIAS) is introduced with the requirements of the public security information construction project, which integrates software and hardware efficiently. It is designed for police officers to collect a suspect’s personal information which will be shared with different police databases in real time, such as basic information, fingerprints, palm-lines, photos, DNA, footprints, communication information, and the like. The personnel information is stored and compared with the varied databases and the matching Results will inform the relevant local police in time automatically. With the help of PIAS, the information collection rate and utilization efficiency are improved dramatically and will be of great help to the crime investigation. In this paper, we present a design and implementation of PIAS, which consists of the multi-functional software and the well-designed information acquisition hardware. The hardware includes a personal computer as the control terminal, different information acquisition equipment, which are integrated on a worktable designed up to the standard of ergonomics. Such details are explained as on software architecture, database design, network topology, system interface with the sequence diagram and functionalities of the system. The information collected by the equipment is then processed and transferred in the format compatible with different databases. The personal data is stored and compared in different databases, and the hit Results will be transmitted automatically to the terminal in local police station. For example, a fugitive will be identified immediately if his fingerprint matches with the one at the crime scene database and the feedback will be to sent the local police shortly after the criminal’s fingerprints are recovered. In order to implement this function well, the information acquisition system has access to other databases. If this system is used in a certain province, it has to implement interfaces specified for the local databases or integrative application platform of the police in that province different from others. The system also provides the basic functions for management such as user and authority management, message management, information acquisition equipment management, system log, statistical analysis, etc. It is believed that with PIAS, information sharing between above all public security information systems will be much easier, practical and accurate.
