Problems solved by technology

Although this solution will not be affected by storage media and transmission protocols, this method needs to manually convert the electronic document into the file format of a special reader after the file is generated, so the operation is cumbersome
In addition, since this method requires the user to manually convert the format, it cannot prevent the user from actively leaking the secret

Abstract

The invention discloses a file protection device which is arranged on a client side. The client side is provided with an operating system. The operating system is divided into a user space layer and a kernel layer. The file protection device comprises an encryption and decryption module and a self-protection module. The encryption and decryption module runs on the user space layer and monitors operation which is conducted on files by an application on the client side. When the file content is read by the application, the encryption and decryption module obtains encrypted file content from the client side, decrypts the encrypted file content, and places the decrypted content into a temporary storage space to be read by the application. When the file content is stored in the application, the encryption and decryption module encrypts the content in the temporary storage space and stores the encrypted file. The self-protection module runs in the kernel layer and monitors the temporary storage space so that other applications except the application can be prevented from having access to the temporary storage space. The invention further discloses a file protection system with the file protection device and a corresponding file protection method.

Description

technical field [0001] The invention relates to the fields of computers and the Internet, in particular to a technology for preventing documents from being leaked. Background technique [0002] With the popularization and development of computer technology and network technology, abundant network data resources have brought great convenience to people's life, but also brought a lot of confusion. For example, in enterprises, employees can easily transfer some Files involving company secrets are sent outside the company, resulting in file leaks. Therefore, there is a need for a solution that can protect the document to prevent the content of the document from being circulated. [0003] Various schemes have been provided to prevent documents on computing devices from being compromised. One solution is to install special software on computing equipment to block hardware interfaces (such as USB interfaces, infrared interfaces, etc.) and to close network protocols (FTP, HTTP, et...
