Embodiment Construction

[0019] Domain control technology has been widely used in networks deployed by various social organizations. Based on domain control technology, the present invention proposes a more efficient and secure file processing mechanism to meet various stringent requirements of users on information security issues. In the following description, an AD (active directory, active directory) domain based on the LDAP protocol will be used as an example for illustration. Of course, the present invention does not exclude other implementation manners.

[0020] In a software implementation, the present invention provides a file security control device. Please refer to figure 1 , the device runs on the user host as a client program, and the basic hardware architecture of the user host includes CPU, memory, input and input devices, non-volatile memory (such as hard disk) and other hardware. The file security control device can cooperate with the domain control server in the domain. Logically, ...

Abstract

The invention provides a method for file safety control and a corresponding device. The method and device is mainly applied to a host computer. The method includes the steps that step A, when a logged-in domain user copies files in a local disk of the current host computer to the outside, corresponding encryption keys of the current files needing to be copied are obtained, and step B, the encryption keys are used for encrypting plaintext data in the current files to form ciphertext data, and encryption identifications corresponding to the encryption keys are stored in a plaintext region of the encrypted files. Compared with the prior art, the method and device improve efficiency of file interchange among users in the organization on the premise of guaranteeing file information safety.

Description

technical field [0001] The invention relates to electronic file processing technology, in particular to a file security control method and a corresponding device. Background technique [0002] With the promotion of information technology, various large-scale social organizations, including government agencies and enterprises, are increasingly inclined to use electronic methods to store their own business and management data. Taking enterprises as an example, the financial statements, employee files, design drawings, audio-visual materials and other data of most enterprises are usually stored in the form of electronic files. Electronic files have become an irreplaceable data storage method. [0003] Compared with traditional paper documents, electronic documents have various obvious advantages. For example, electronic documents are easier to be disseminated than traditional paper documents, but the ease of dissemination means that electronic documents are more likely to cau...
