Problems solved by technology

[0005] 1. File storage If the device is hacked, the door will be wide open for anyone to use
[0006] 2. The file storage has the problem of being lost or changed (tampered or covered up)
[0007] 3. Existing file encryption methods are often cracked
[0008] 4. If the file is downloaded or taken away, it will not be possible to issue a new version or recycle it later
[0009] 5. Many file formats and documents are often printed in paper (because of national conditions or conditions, they need to be printed out). How to control confidentiality becomes a problem

Abstract

The invention discloses a file fragmentation encryption engine and a technology thereof. The file fragmentation encryption engine comprises a file fragmentation module, an encryption server, a fragmentation chain node module and a distributed queue repository. The file fragmentation module divides the confidential file to generate a plurality of file fragments and file indexes thereof. The encryption server encrypts each file fragment and each file index to generate a plurality of encrypted file fragments and encrypted file indexes. The fragmentation chain node module further scatters and encrypts each encrypted file fragment and each encrypted file index in a fragmentation node mode to generate a plurality of encrypted file fragment chains and encrypted file index chains. The distributedqueue repository stores a plurality of encrypted file fragment chains and encrypted file index chains.

Description

Technical field: [0001] The invention relates to a file processing system and its method, in particular to a file fragmentation encryption engine and its technology. Background technique: [0002] Since the advent of computers, digital files have been stored in file formats, such as PDF, DOC, XLS, PPT and other file formats. With the popularization of computers, most files are generated, and word processing systems are used for file processing and processing. store. [0003] However, in view of the popularization of computer and network systems, information security issues have become a hidden concern. Electronic files stored in computers have exposed related security issues in the storage of file formats. In recent years, many information security systems have targeted File storage is encrypted and protected; in short, it compresses and assigns passwords to files in various file formats, and then develops a system for reading or unlocking files as a mode of file decryption...
