Management of Data Base System for Surveillance Based on Motion Detection

[[abstract]]Video surveillance system is a powerful tool not only in public environment protection, but also in home and private security service. Digitizing capture is one of the most important technique in current video monitor area. By using motion detection and Internet control, we can view, control, or alert remotely. Furthermore, digital video surveillance system can slash our budget of storage. Most of the experimental or commercial video surveillance systems, they emphasize three important part, which are live video transmission, motion detection, and remote control. However, when we enjoy the convenience of this system, the security of transmission and the media of storage lead to some serious problems in this system. For example, unauthorized people may illegally access the system and stolen private images or data. Therefore, we need add some special processes to mend these gaps and create a safe operation environment. In my study, I work on the management of the database for a secure surveillance system. I focus on the safety of exchanging files between websites and databases with the following issues. 1. Confidential Information: Encrypting data before transmission, enhance the privacy of system. 2. Information Hiding: Hiding the file name by java script, and decrease the chance of unauthorized accessing. 3. Data Integrity: Using message digest to analyze the accuracy of transmission. 4. Identification: Identifying accessing password to avoid nauthorized users. 5. Access Control: Grouping users by limits of authority, prevent data interchange between different authority level. To achieve safety goals, the following techniques were used: 1. Using ASP (Active Sever Pages) to control database and combine Confidential Information, Information Hiding, and Access Control; 2. Using one-way hash function (MD5) to analyze the accuracy of transmission; 3. Encrypting files by PGP(Pretty Good Privacy) which can not only ensure the security of files, but also identify the authorized users
