Embodiment

[0026] Users use smart phones or tablet computers, user group A includes user A1 and user A2, user group B includes user B1 and user B2, user group A or user group B can increase the number of users according to the situation, and users are connected through wireless network To the server and connect to each other through the wireless network, user A1, user A2, user B1, and user B2 need to access the server through the wireless network for identity authentication every time they start up. After identity authentication and registration, determine the user's authority and grouping .

[0027] Assume that user A1 and user A2 have permission levels set to advanced, and user B1 and user B2 have permission levels set to high and low respectively. When user A1 creates a new word document, the system will automatically pop up a prompt box for setting the security level. The security levels include public, common, and Private, Confidential, Confidential, Top Secret and other encryption ...

Abstract

The invention discloses a file safety management system based on a mobile terminal. The system is realized by an authority grouping module, an access identity authentication module, a key distribution module and a security classification management module, a terminal user and a user group are connected to a server by a wireless network and are connected with each other by the wireless network to transmit and receive a file; and due to the adoption of the methods such as access identity authentication, authority grouping and key distribution, not only can file authorization and security classification management in the mobile terminal be realized, but also the inquiry of a ciphertext can not be affected by the error of the ciphertext under the condition of the error code or packet loss of a wireless network, and the error code robustness is good.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a file security management system based on a mobile terminal. Background technique [0002] In recent years, more and more mobile terminals such as smartphones and tablet computers have been used by people, and many enterprises and government agencies have also begun to use mobile terminals for mobile office, mobile law enforcement and other applications, and work efficiency has been greatly improved. However, most of the file security management systems applicable to PC terminals cannot be directly applied to mobile terminals due to differences in system software, hardware, and network conditions, and the security threats faced by files in mobile terminals are increasing day by day. [0003] A solution is described in the patent titled "Outgoing Document Security Management System Supporting Collaborative Work" (Application No.: 201010138182.0), which uses various technologi...
