Summary
Shared care models in healthcare necessitate secure, cooperative health information systems. This study explores how CORBA middleware can enhance data protection and application security in these evolving systems.
Area of Science:
- Health Informatics
- Computer Science
- Information Security
Background:
- Healthcare systems are shifting towards 'shared care' due to economic pressures and changing care conditions.
- This shift necessitates cooperative health information systems that span organizational, technological, and policy boundaries.
- Distributed and heterogeneous health information systems increasingly rely on middleware solutions like CORBA.
Purpose of the Study:
- To describe how CORBA middleware can provide application and communication security for shared care health information systems.
- To analyze CORBA's security services in the context of healthcare data protection requirements.
- To identify current security gaps in healthcare middleware and propose solutions.
Main Methods:
- Review of CORBA architecture and its security services.
- Analysis of security requirements for sensitive patient and user data in healthcare.
- Discussion of CORBAmed experience and proposed solutions.
Main Results:
- CORBA offers possibilities for achieving application and communication security in distributed health information systems.
- Existing CORBA specifications include security services relevant to healthcare needs.
- Specific security services required in healthcare but not yet available in CORBA were identified.
Conclusions:
- CORBA middleware can be leveraged to enhance security in shared care health information systems.
- A proposed solution utilizes available CORBA security services and remains adaptable to other middleware like DHE or HL7.
- Addressing identified security gaps is crucial for robust data protection in modern healthcare IT infrastructure.
