Communication security in open health care networks.

Area of Science:

• Health Informatics
• Network Security
• Data Interoperability

Background:

• The need for interoperable health information systems to support shared care models.
• Challenges in securing sensitive personal medical information across diverse organizational and geographical boundaries.
• Requirement for robust security solutions in health data exchange.

Purpose of the Study:

• To develop an open and interoperable security framework for health information systems.
• To address the security challenges in exchanging sensitive medical data across networks.
• To implement a practical security solution for electronic data interchange (EDI) in healthcare.

Main Methods:

• Development of a generic security model for health data.
• Implementation of secure messaging protocols for healthcare data exchange (HL7, EDIFACT, XDT, XML).
• Integration of security measures for both message content and data transport (e.g., SSL, TLS).

Main Results:

• An open security approach for healthcare EDI has been specified and implemented.
• Demonstrated secure mailing and secure file transfer (FTP) by wrapping sensitive information.
• The developed solution ensures data security during transmission over unsecure networks and via secure channels.

Conclusions:

• The MEDSEC project provides a viable open security solution for health data interoperability.
• The implemented methods offer practical security for electronic health record exchange.
• The results are being prepared for standardization to promote wider adoption.
