Method for controlling access permissions of electronic document

Abstract

The invention discloses a method for controlling access permissions of an electronic document. The electronic document is composed of at least two basic units, and the basic units with permissions each have at least one permission. When a user has access to the electronic document, the user has access to the basic units in the electronic document and obtains the permissions corresponding to the basic units. On the basis of the electronic document, the granularity of safety control is decreased to a more detailed basic unit level, and safety of the electronic document is effectively guaranteed by technological means.

Description

technical field [0001] The invention relates to a management system for electronic document security, in particular to a method for controlling the access authority of electronic documents. Background technique [0002] In the office process of social activities such as e-commerce and e-government, the processing of documents is a very important part, but there are a series of problems in paper documents themselves, such as high printing costs, once the business changes, the previous paper documents Most of them will become invalid; storage and management costs are high; transmission and circulation efficiency is low; data filling quality is not high; data needs to be entered manually; security during transmission is difficult to guarantee; data access rights cannot be controlled, etc. [0003] Therefore, in various activities in modern society, the introduction of electronic document system has become a trend. At the same time, in the electronic document system, it is also ...

AI Technical Summary

Problems solved by technology

[0004] (1) The security technology designed for the electronic document system mainly prevents external threats, and lacks the protection against internal threats of the enterprise, and the leakage of enterprise sensitive information is mostly caused by internal users intentionally or unintentionally;

[0005] (2) There is a lack of continuous protection for the information contained in the document. The documents protected by the aforementioned technologies are all at the document level, and cannot provide continuous protection for the entire life cycle of the document at the granularity of the basic unit;

[0006] (3) The document information protection strategy of an enterprise often stays on paper and cannot be implemented using technology. Relying on the user's self-discipline and sense of responsibility to achieve it may bring unacceptable risks to network security, even if it is an accidental security loophole , can also have serious consequences
