Research on an Access Control Model for Radio and Television Monitoring Software Based on T-RBAC

With the rapid development of radio and television industry, the use of software to improve the security of broadcasting and TV system by monitoring the radio and television equipment is becoming widely adopted, So how to improve the authorization management model of software to meet the need of detailed sub-division of authority and dynamic authorization becomes the focus of the industry and has practical significance. This paper first introduces the design concept, module composition of the radio and television integrated monitoring and management system (RTIMMS). In the second place, this paper reviews advantages and disadvantages of the most frequently used models including Role-Based Access Control (RBAC) and Task Based Access Control (TBAC). By researching and comparing two models above, the paper presents a mixed model called (T-RBAC) and divides tasks in two categories and related events respectively. The process of authority management is based upon the tasks, rules in rule base and usage count of permission. The diagram of T-RBAC authorization model is also introduced in the end.
