Disk protection system of tree-form multilayer cover layer of sector increment and implementing method thereof

Abstract

The invention provides a disk protection system of a tree-form multilayer cover layer of a sector increment and an implementing method thereof. The disk protection system and the implementing method comprise a disk filter drive, a configuration information module, a current layer and a history cover layer, wherein the disk filter drive is used for implementing reading-writing redirections to writing filter data of a protected partition through the current layer and the history cover layer, the configuration information module is used for storing a configuration information structure which consists of multiple levels structures; the multiple levels of structures include a disk protection system configuration information sector, multiple cover layer information of each partition, position information of each cover layer of the partition and a layer information sector in turn; the address of the next level of structure is stored in the front level of structure, and the tree-form hierarchical structure of multiple layers of cover layers can be analyzed only through the disk protection system configuration information sector. According to the disk protection system and the implementing method, multiple layers of covering layers are effectively organized through a configuration information structure so as to support multiple functions of the cover layers, each cover layer is of a tree-form organization structure, and the privacy and the safety of the data in each cover layer can be protected.

Description

【Technical field】 [0001] The invention relates to a disk protection system with sector incremental tree-shaped multi-layer covering layer and its realization method. 【Background technique】 [0002] In the current complex network environment, various viruses and Trojan horses are everywhere. People pay more and more attention to the protection of the operating system and important data in the operating system, and there are more and more software to protect the operating system. However, as customers The application environment is becoming more and more complex, and the amount of data is increasing. Ordinary protection software cannot meet the needs at all. People hope that the protection software can support the function of multi-layer overlays, which can not only protect the security of the system, but also efficiently and conveniently Manage your own data.

[0002] In the current complex network environment, various viruses and Trojan horses are everywhere. People pay more and more attention to the protection of the operating system and important data in the operating system, and there are more and more software to protect the operating system. However, as customers The application environment is becoming more and more complex, and the amount of data is increasing. Ordinary protection software cannot meet the needs at all. People hope that the protection software can support the function of multi-layer overlays, which can not only protect the security of the system, but also efficiently and conveniently manage your own data

Microsoft's EWF hard disk protection can support the function of multi-layer overlay, so that customers can restore their data to the previous state, but EWF hard disk protection only provides a simple linear overlay function, which cannot meet customers' more complex system applications , and there will be the following problems during use:

[0004] 2. When EWF generates hard disk protection, there must be a free disk space in the disk to build an overlay layer. If the hard disk protection cannot be generated when there is no free space on the disk, some customers may need to rebuild a new system to meet the generation requirements. Protection conditions; and when EWF generates memory protection, when the physical memory is used up, the system will blue screen, which limits the usage scenarios of EWF

[0005] 3. EWF hard disk protection only provides the version on the Windows XP Embedded operating system, and does not provide the version running on the Windows XP and Windows 7 operating systems, which greatly limits the use of most users
