Study on Fuzzy Theory Based Web Access Control Model

Along with the constant development of online services, the application of traditional RBAC model for the user-role assignment and maintaining the user-role assignment become an arduous and error-prone task. In order to solve these problems, this paper proposes a trust based user-role assignment model for assign role to users. It is based on the userspsila trustworthiness in the system, which is a fuzzy concept, the application of fuzzy theory to calculate the trust degree of users and the trust degree that the role needed, provides a new method for the user-role assignment.
