Blood relationship description system for entity trust in information system

Abstract

The invention relates to the technical field of information safety, and particularly relates to a blood relationship description system for entity trust in an information system. Aiming at the problems that at present, the entity relationship description mechanism is in lack, the entity relationship is converted to the entity trust because of the lack and the like, the inheriting relationship among entities in the information system is expressed by virtue of an idea of biological blood relationship and a blood relationship description method, and an entity trust evaluation system based on theinheriting relationship is established. In the system, the inheriting relationship among the entities is described by using a family tree, so that an evolution rule and an identification method for the inheriting relationship as well as a rule for converting the entity relationship into the entity trust are drawn up, a set of methods for describing the entity trust based on the entity inheriting relationship are established; the blood relationship description system for the entity trust in the information system designed according to the method can be applied in a network community, so that users in different relationships have different information access permissions; and the blood relationship description system can be applied in an enterprise information system, so that the safe share and protection of various resources can be achieved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a blood relationship description system of entity trust in an information system. Background technique [0002] The information system has changed from closed to open, and the traditional security methods lack flexibility and cannot meet the requirements of protecting information security in an open environment. In recent years, research on trust in computers has been carried out while developing traditional security techniques. Endow the entities in the information system with human characteristics, measure and evaluate the trust degree between entities through various methods, and provide a more flexible security measurement mechanism for the information system. [0003] In human society, the trust between people can be evaluated in two ways, one is based on rational calculation, and the other is based on the emotional connection between people. At present, the c...
