Research and application of role-based access control model in medical system

Role based access control(RBAC)is a mainstream technology applied to the system control user access. Accord ing to the characteristics of the medical system,an access control algorithm is put forward in this paper. On the basis of RBAC model,the access subject and object in the medical system is analyzed,the role is introduced into the system,the permissions is associated with role,and the control for different users' access to records is investigated emphatically. by assigning a role to the appropriate user,then confering an appropriate access privilege on the user,and making the user and access logic separat ed,the flexibility and security of the permission assignment and access control in the medical system are improved.
