A takeout management system for file datas

Abstract

The invention provides a takeout management system for file datas and aims to improve the security of secret data. In the system, a file separating device establishes data communication connection with an encrypted storage disk and a file operation terminal; the encrypted storage disk is connected with the file operation terminal via a pluggable interface; the file operation terminal is operated by a user carrying the encrypted storage disk. The file separating device is used for separating secret file data into a first decomposition sub-file and a second decomposition sub-file and sending the first decomposition sub-file to the encrypted storage disk and the second decomposition sub-file to the file operation terminal. The encrypted storage disk performs encrypted storage of the first decomposition sub-file. The file operation terminal stores the second decomposition sub-file. When the encrypted storage disk and the file operation maintain connection, the secret file data can be obtained by reading the first decomposition sub-file from the encrypted storage disk and merging and restoring the first decomposition sub-file and the second decomposition sub-file.

Description

Technical field [0001] The invention relates to the field of computer technology, in particular to an out-of-band management system for file materials. Background technique [0002] With the widespread popularization of computer technology, the documents and materials of many units are currently stored electronically. When personnel in the unit go out on business, it is inevitable that they need to carry confidential materials. When personnel carry secret materials, there may be leaks In order to ensure the security of the unit’s data, in the prior art, unit users often use encryption algorithms to directly encrypt the data that needs to be carried to manage the document data. The document user decrypts the document by entering a password. It is difficult to prevent copying, stealing, and cracking of classified data files by only encrypting classified information, and it cannot realize the centralized and unified management of classified electronic documents, and cannot meet the ...

[0002] With the widespread popularization of computer technology, the documents and materials of many units are stored electronically. It is inevitable that the personnel in the unit need to carry confidential information when they go out on business, and there may be leaks when personnel carry confidential information. Risk problem. In order to ensure the security of unit data, in the prior art, unit users often manage documents by directly encrypting the materials that need to be carried with encryption algorithms. Document users decrypt documents by entering passwords, but this It is difficult to prevent the duplication, theft, and cracking of confidential data files by only encrypting confidential information, and it is also impossible to realize the centralized and unified management of confidential electronic documents and materials, which cannot meet the requirements of security, confidentiality and centralized control
