Electronic document security management system and method based on digital markers

Abstract

The invention provides an electronic document security management system and method based on digital markers. The system comprises a digital marker generation module, a document security use module, adocument security circulation module and a document security output module. The method specifically comprises the following steps of generating a security attribute for an electronic document by utilizing the digital mark generation module, and carrying out digital marking on the electronic document according to the security attribute; performing security control and auditing on the use of the digitally marked electronic document by using the document security use module; performing security control and auditing on the circulation of the digitally marked electronic document by utilizing the document security circulation module; and performing security control and audit on the output of the digitally marked electronic document by using the document security output module. By means of the blockchain technology and the digital marking method, a safety management problem of the electronic document is solved, and overall safety and use efficiency of the electronic document safety management system are greatly improved.

Description

technical field [0001] The invention relates to the field of document security technology management, in particular to a digital mark-based electronic document security management system and method. Background technique [0002] Information and data such as electronic documents are the core assets of the company and the lifeblood of the enterprise. Protecting data security is the source and basic work of protecting state secrets, commercial secrets and personal privacy. At present, the mainstream solutions for electronic document security protection and data leakage prevention at home and abroad lack the unique identity mark for the data itself and the unified security control method based on the mark. There is a lack of a unified data security management and control "grasp", and the transmission of trust and the connection of management and control between various business systems and security products cannot be carried out. In addition, the data computing environment lack...

Problems solved by technology

[0004] Existing document marking technologies, including watermarks and signatures, are not secure enough. The corresponding attribute information is not bound to the document, and most of them are stored in a centralized database. Document marking and attribute information are easy to be separated and tampered with. The risk of a single point of failure is also prevalent in data centers
