Research On Security-check Information System Based On Multi-information Fusion

Along with the vigorous development of the domestic and foreign aviation shipping industry, the huge passenger capacity brings much aviation security problems, which causes the security-check work in civilian airport face the severe challenges. As the information be checked and inspected during the security-check process is massive, how to fuse connect these information and forms an information security-check system to help implement security-check work efficiently should be taken seriously by each airport.Through inspect the existing security-check pattern and the service demand of airport, this thesis carrys the demand analysis and project design to the establishment of security-check information system. The information of security-check process should be gathered include:the boarding card barcode information, the individual status information, the leaving port information, the passenger's picture, the X-ray picture, the security check process video, the package video and the related staffs and equipments'information and so on. As these information comes from different equipments and different places and the information format is also diverse from each other, so this thesis use multi-technology, including database and its visiting technology, FTP file transfer technology, socket network communication technology, barcode technology, digitalized video technology and so on to realize the connection of these information, and designs the fuzzy query function, which enables these information to reappear on a contact surface in order to provide the evidences for afterward trace.Besides connecting the information, this thesis also designs the early warning function. It calculatedly demonstrates the warrant information from public security office on system's contact surface to strengthen staffs'vigilance. Meanwhile, let the passengers'information compared to the suspects under strict surveillance database to intercept dangerous person, and also can add the dangerous person who discovered in the security-check process into suspects under strict surveillance database momentarily.Some workstations need to gather the passengers'security check videos, so this thesis expands the video acquainting function, realizes the videos'long-distance monitoring function.Besides, this thesis designs the channel passenger capacity statistics and the contrast inquiry function between channels and demonstrated in figures and diagrams effect, and equipments, staffs, suspected persons'information maintenance functions as well.Massive applications of information technology does not only make the system more intellectualized and automated but also bring security risks, This thesis analyzes the possible physics, network, system and application security risks and give the safe design and the security policy to make system become more perfect and strong.
