Summary
This study introduces a secure chip card based medical information system (CCMIS) to improve patient data sharing among healthcare providers. The DIABCARD project enhances communication and security for distributed health information systems.
Area of Science:
- Health Informatics
- Information Security
- Distributed Systems
Background:
- Distributed and interoperable health information systems are essential for shared care.
- Protecting sensitive patient data requires robust security services and access controls.
- Chip card based systems offer enhanced data security, user control, and mobility.
Purpose of the Study:
- To implement and evaluate a chip card based medical information system (CCMIS).
- To facilitate secure communication and cooperation among healthcare professionals for shared patient care.
- To address security needs for distributed health information systems, using diabetes care as a model.
Main Methods:
- Development of a chip card based medical information system (CCMIS) within the DIABCARD project.
- Integration of security services like strong authentication, authorization, and access control, in cooperation with the TrustHealth project.
- Implementation of secure handling of patient chip cards and secure communication between workstations and departmental systems.
Main Results:
- A functional CCMIS prototype was developed and evaluated, demonstrating feasibility.
- Enhanced security services specification for CCMIS was provided based on study outcomes.
- Secure communication channels and data handling protocols were successfully implemented.
Conclusions:
- Chip card based medical information systems can significantly improve shared care and data security.
- The DIABCARD solution provides a secure framework for distributed health information systems.
- Future work includes implementation in a health network and consideration of legal issues and emerging standards like XML.
