The problem is to provide a uniform mechanism to integrate this information. This paper documents the results of an investigation into the suitability of several different distributed access mechanisms. These mechanisms were compared with regard for use in health care applications. Protocols utilized Performance of the transport mechanism. RBAC is a security mechanism that is more flexible than Mandatory Access Control, but easier to use than just plain access control lists.
Every user is assigned to one or more roles.
Each role can perform some operations but not others. A demonstration application was constructed that used the distributed communication methods to implement a patient record database. This report discusses how these mechanisms were used in the demonstration project and the results found. Not unsurprisingly, we discovered that each of the mechanisms were effective for different purposes. These findings are discussed in detail in this report.
