According to the security management requirements to the rated mobile storage medium, a novel mobile storage medium security management architecture instanced by the U disk was proposed, which based on the USB and MSC specification. The unique identification was composed of VID, PID and hardware serial number. The scheme of USB medium management was provided, which based on the CY7C67300 EZ-HOST microprocessor. Through the USB enumeration the unique identifier information of U disk was obtained and it was displayed on the hyperterm program. The test results show that the unique information and identification method can be used for mobile storage medium security management system, so that rated mobile storage media were under real-time surveillance and control, which greatly reduced the confidential information leakage risk.
