An improved RBAC model and its application in a Management Information System

To achieve high efficiency in human resource management, University Human Resource Management Information System (UHRMIS in short) requires hierarchical architecture, clearly defined modules and effective cooperation of multiple users. So this paper presents Improved Role Based Access Control model (IRBAC model in short), a new access control model and the application of IRBAC model in UHRMIS is also covered. IRBAC model has realized flexible configuration on access control, provided different security degrees and decreased hidden dangerous factors caused by discretionary authorization so as to lay reliable foundations for higher efficiency of UHRMIS.
