Gradient-based non-perceptual encryption and decryption system and method

Abstract

The invention discloses a gradient-based non-perceptual encryption and decryption system and method. The method comprises the following steps: S1, issuing an encryption program to a terminal through a server; s2, decrypting the file line by a decryption unit; s3, automatically encrypting the file of the specified type according to the transparent encryption unit; s4, performing manual encryption limitation on the file through the semitransparent encryption unit; s5, identifying and encrypting the file content keyword according to the intelligent encryption unit; s6, performing partition storage protection on the encrypted file through a transmission protection unit; the transparent encryption unit, the semitransparent encryption unit, the intelligent encryption unit and the transmission protection unit are used for intercepting the read / write request of the file system in real time, and dynamically tracking and transparently encrypting / decrypting the file, so that the file encryption / decryption is dynamic and transparent, the state of the original file is not changed, and the gradient type non-perceptual encryption / decryption effect is achieved.

Description

technical field [0001] The invention relates to the technical field of file encryption, in particular to a gradient-based non-perceptual encryption and decryption system and method. Background technique [0002] With the continuous development of the domestic economy, informatization has become an important means of daily office work for enterprises. According to statistics from relevant departments, more than 80% of enterprise data has been digitized. In some specific industries such as manufacturing, financial industry, The degree of digitization of data in the communication industry is higher. The digitization of data has brought huge efficiency improvements to enterprises. Compared with the paper documents used in the past, the circulation of electronic documents is no longer subject to specific transmission channels and transmission efficiency. The convenient use of storage media has greatly improved the information communication within the enterprise and with the outs...

Problems solved by technology

[0004] The present invention solves the problem that the existing encryption and decryption methods easily affect the user's operating habits and cannot perform multi-mode hierarchical encryption, and proposes a gradient-based non-perceptual encryption and decryption system and method to protect important files in multiple ways The kernel-level processing of the central processing module prevents temporary plaintext files from being generated during the encryption process, prevents data from being illegally cracked, and has the effect of gradient-type non-perceptual automatic encryption
