Problems solved by technology

In fact, high-strength encryption algorithms are difficult to obtain, and the speed of being cracked is increasing, and the cracking technology is constantly making breakthroughs; the cost of key management is also huge; a complete authentication and authorization mechanism is difficult to implement in small-scale systems, so It is very difficult to realize low-cost high-intensity security management without destroying the integrity of electronic document information

Embodiment 1

[0046] A network-based file separation storage and transmission management system, including a network service device, a separation and restoration separation and restoration terminal device (hereinafter referred to as a separation and restoration terminal device), the system separates all electronic files into main block files and The block files are separated and stored in different storage media, and the main block files are associated with the separated block files through a file name pointer.

[0047] Further, the network service device includes a separate block file storage device and an access control device, and the separate block file storage device sets a user data area for each user to store all the separate block files of the user; the access The control device connects and manages the storage device of the separated block files, and is responsible for the provision, recovery, update and maintenance of the separated block files according to the request of the termin...

Embodiment 2

[0054] A network-based file separation storage and transmission management system and method provided by the present invention includes the following steps:

[0055] A. Set the initialization work of the "terminal file" document;

[0056] B. The user edits and uses the "terminal file" file on the separate restoration terminal device based on the dedicated storage device;

[0057] C. "Terminal file" file submission processing;

[0058] D. Between the special storage device and the network service device, the main block and separate block files must be updated synchronously, and the integrity of the update process must be guaranteed. If the update process is interrupted or an error occurs, the files on the special storage device and the network service device must be returned Back to the initial state.

[0059] Electronic documents are separated into two file pairs, the main block and the separation block, through random transformation and random information extraction. Neithe...

Embodiment 3

[0074] 1. System composition and functions

[0075] as attached figure 2 As shown, the system consists of two parts, the management server and the management terminal.

[0076] (1) The separation management server includes a separation block file storage area and a management control module. The separate block file storage area sets up a user data area for each user to save all the separate block files of the user; sets up a filing data area to record the filing information of file transmission for legal approval; the management control device connects and manages The separated block file storage area is responsible for the provision, recovery, update and maintenance of separated block files according to the end user's request, ensuring the consistency of "network file" file separation management, responsible for credential checking and identity verification during file transfer, ensuring The split chunk file is transferred to the correct recipient.

[0077] (2) The termin...

Abstract

The invention discloses a network-based file separate storage and transmission management system and method. An electronic file is separated into a main body block file and a separate block file through conversion and information extraction, and the two files cannot recover original texts or original text fragments independently, and when the two are cooperated, restoration can be realized conveniently. The file is set to be in two states: a network file and a terminal file; the network file is in separate storage in a network manner, and the separate block file and the main body block file are stored to a network service device and a dedicated storage device respectively; and the terminal file is in separate storage in a terminal manner, and the separate block file and the main body block file are stored to terminal hard disk and a dedicated storage device respectively. The system, through application management and access control, allows a user to be able to edit and use the network file through any network terminal, realizes separate file transmission between internal users, and ensures that the files are restored only in internal storage without storing (transmitting) the original texts or original text fragments in any medium.

Description

technical field [0001] The invention relates to the field of security management of data files, in particular to a network-based file separation storage and transmission management system and method. Background technique [0002] With the development of information technology, networks and computer systems have improved the ability to share data and equipment, but it has brought serious hidden dangers of various types of data being copied arbitrarily, or even illegally stolen. Electronic files are the most popular and widely used information carriers, and their security protection is the key content of information security. The technical means of electronic file security protection mainly include the following methods. [0003] (1) Access control based on identity authentication. Typically, the server centralized storage method is adopted. After the client has the server to authenticate the user identity, the client is granted corresponding permissions, such as reading, wri...
