Security threats and solutions in distributed, interoperable health information systems using middleware.

Abstract

Increasingly, distributed, interoperable healthcare information systems, which meet the shared care paradigm, work across the boundaries of policy, organisational, and technological domains and are based on middleware concepts. Especially in healthcare with its sensitive personal and medical data, such systems require advanced data security measures. In the paper, a common object-oriented security model for middleware systems and advertisements for implementation are proposed, corresponding the security requirement of both the user and the application environment.
