다국어 초록 (Multilingual Abstract)

The health care system revolutionized by the use of information and communication technologies. Computer information processing and electronic communication technologies play an increasingly important role in the area of health care. Role Based Access Control(RBAC) has recently received considerable attention as a promising alternative to traditional discretionary and mandatory access controls, which ensures that only authorized user are given access to protected data or resources. This paper proposes access control model for solution of problem connected with patient's information and private protection. We propose a context based access control model for health care information systems, which combines role-to-role delegations, denial permission, context concept and dynamic context aware access control. With out approach we offer great flexibility and fine-grained access control in healthcare information systems.
