Data file security management system and method based on information separation

Abstract

The invention discloses a data file security management system and method based on information separation, and belongs to the field of security management of data files. The system comprises an office interface module, a document transformation module and a security main file and SK file generating module, wherein the office application interface module is used for acquiring file reading-writing operations of an office system and calling the document transformation module, the security main file and SK file generating module, the document transformation module is used for generating a characterless data file and inversely transforming the characterless data file, the security main file and SK file generating module is used for extracting information of the characterless data file formed in the document transformation module according to random seeds to generate a security main file and an SK file. Random diffusion of protected data files can be prevented by the system and the method, and contents of the protected data files are prevented from being illegally stolen or cracked.

Description

technical field [0001] The invention relates to the field of safety management of data files, in particular to a data file safety management system and method based on information separation. Background technique [0002] With the development of information technology, the network and computer system have improved the sharing of data and equipment, but it has brought information and data to be illegally stolen, copied, used, etc., which has greatly affected the security management of sensitive data within the enterprise. At present, files are mainly managed through encryption algorithms and authentication and authorization methods, but for encryption, high-strength encryption algorithms are difficult to obtain, effective management of keys is costly, and decryption technology and computing speed are constantly improving. It also constantly threatens the security of the ciphertext. For authentication and authorization, a complete authentication and authorization mechanism is...

Problems solved by technology

[0002] With the development of information technology, the network and computer system have improved the sharing of data and equipment, but it has brought information and data to be illegally stolen, copied, used, etc., which has greatly affected the security management of sensitive data within the enterprise. At present, files are mainly managed through encryption algorithms and authentication and authorization methods. However, for encryption, high-strength encryption algorithms are difficult to obtain, and the cost of effective key management is huge. With the continuous improvement of decryption technology and computing speed, It also constantly threatens the security of the ciphertext

For authentication and authorization, a complete authentication and authorization mechanism is difficult to implement in small-scale systems

Therefore, according to existing technical means, it is difficult to achieve low-cost and high-intensity security management for core data
