Hidden file management system based on steganography

Abstract

The invention provides a hidden file management system based on steganography. The hidden file management system based on steganography comprises a storage space integration unit and an operation unit, wherein the storage space integration unit is used for abstracting storage space of a carrier file library into continuous storage space formed by splicing a plurality of data blocks; and the operation unit is used for formatting, storing, extracting and deleting files. A safe data storage mode is implemented, scattered storage spaces in a carrier file are integrated, and the hidden file management system is apparent to users, and is convenient to operate and high in portability.

Description

technical field

[0001] The invention relates to the field of steganography technology and the field of data storage security technology, in particular to a hidden file management system based on steganography. Background technique

[0002] At present, various storage devices or systems for storing data have appeared, and at the same time, more and more attention has been paid to the security of storing data. A common method of data security is to encrypt the data and store the key in a storage device or a host device. The disadvantage of this method is that as long as the key is obtained, all data can be deciphered.

[0003] An improved technique is to hide the data in the storage device, thereby protecting the security of the data. At present, the mainstream method to implement this technology is to intercept the system's command to access files, and filter the sensitive files specified by the user to achieve the effect of hiding files. The defect of this method is tha...

Examples

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] like figure 1 As shown, a hidden file management system based on steganography includes a storage space integration unit 1, a formatting operation unit 2, a file storage unit 3 and a file extraction unit 4;

[0033] The storage space integration unit 1 is used to abstract the storage space of the carrier file library into a continuous storage space composed of several data blocks, and use the absolute path of each carrier file in the carrier file library and each data block in its corresponding The offset position in the carrier file is a variable, and the connection relationship between the data block and the carrier file is established;

[0034] The formatting operation unit 2 is used to divide the continuous storage space into a reserved area, a block state area and a data area. The block state area is composed of several block...
