Terminal Sensitive Data Protection by Adjusting Access Time Bidirectionally and Automatically

Along with the rapid development of the Internet, people more incline to access to the network for life needs through intelligent terminal. Once the devices are beyond control, the privacy information are leaked. Hence it's important to protect the data obtained by client. From above view, a terminal sensitive data protection method by adjusting access time automatically is proposed. This method achieves fine grit visit control based on sliding time window, applies dynamic authorization rules based on temporary parameters, employs temporary parameters to identify users and control their visits, and uses the data desensitization to protect sensitive privacy. It can ensure the security of obtained data by client, and also meets the availability of the data. The proposed method employing access control, time authorization and desensitization was compared with those existing data protection methods, as well as its validity was verified.
