Method, system and device for normal mobile storage devices to add data-leakage prevention function

Abstract

The invention provides a method, system and device for normal mobile storage devices to add a data-leakage prevention function. According to the method, system and device for the normal mobile storage devices to achieve the data-leakage prevention function, a normal mobile storage device can be manufactured into a confidential mobile storage device with the data-leakage prevention function. According to the technical scheme, on the basis of a computer operating system, by utilizing driving layer isolation techniques including network isolation, storage isolation, application isolation, peripheral isolation and the like, a safe desktop completely isolated from a system tabletop is created and used for opening the confidential mobile storage device. The method, system and device for the normal mobile storage devices to add the data-leakage prevention function have the advantages that when the confidential mobile storage device is applied to a computer in an open environment, data in the computer can be protected from leakage.

Description

technical field [0001] The invention belongs to the field of computers and relates to a confidential mobile storage device with data leakage protection function. Background technique [0002] At present, the use of mobile storage devices is very common, and there are countless examples of leakage of important documents and personal privacy due to the loss of mobile storage devices, which creates a demand for data protection on mobile storage devices. [0003] In the existing solutions, the confidential mobile storage device is a commonly used data protection method of the mobile storage device, which prevents information leakage to a large extent, but the confidential mobile storage device is usually a special mobile storage device, which can only Use in a trusted environment has certain limitations; although confidential mobile storage devices have data encryption functions, they do not have data leakage protection functions. After decrypting the data, legitimate users can ...

[0003] In the existing solutions, the confidential mobile storage device is a commonly used data protection method of the mobile storage device, which prevents information leakage to a large extent, but the confidential mobile storage device is usually a special mobile storage device, which can only Use in a trusted environment has certain limitations; although confidential mobile storage devices have data encryption functions, they do not have data leakage protection functions. After decrypting the data, legitimate users can copy, save and distribute the data at will. It is easy to obtain the data of the confidential mobile storage device, which cannot meet the requirements of enterprise intellectual property protection; in addition, once the confidential mobile storage device is used, the entire mobile storage device is encrypted, and some files do not need to be encrypted.
