Disk encryption system for shared file

Abstract

The invention discloses a disk encryption system for a shared file. The system comprises a management terminal, a storage module, a client and a security protection module. The management terminal, the client and the storage module are connected to each other through a remote network. The management terminal comprises a management terminal login unit, a key display unit and a feedback receiving unit. The storage module includes a registration information storage unit, a login information storage unit, a key database, and the shared file. The client includes a client registration unit, a clientlogin unit, a face collecting unit, a key sending unit and a key input unit. The security protection module includes a key matching unit, a matching counting unit, a key generating unit, and a matching feedback unit. The protection of the shared file by the disk encryption system proposed by the invention is safe and effective without the limits of region and time, an alarm device can be automatically or manually activated, the information of a user is stored and registered, and the responsibility is quickly pursued.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a disk encryption system oriented to shared files. Background technique [0002] Shared file is a new means of file sharing, through file sharing, users can make people on different servers enjoy the same shared file, so that the utilization rate of resources is higher. Shared files are frequently used in our daily life. For example, companies use shared files to transmit internal company files and materials at work. In schools, teachers share resources such as videos and courseware with students through shared files. Graduates can also use shared files. Papers are uploaded to shared files for students to search and study. These are all applications for sharing files. Shared files bring convenience to people, allowing recipients to use resources in shared files in an unlimited time and unlimited regions. [0003] With the increasing frequency and scope of shared fi...

Problems solved by technology

At present, encrypted shared files are only used in a relatively short distance, such as users in the same local area network, and the scope of use is small. Special managers are required to manage encrypted files and users of encrypted files. Only the permission of the manager can be used. Encrypted shared files increase the workload of the administrator, and the usage time is also limited
