A secure multi-agent system enables secure Internet-based health record exchange between different hospital systems. This approach ensures data protection and interoperability for cooperative healthcare and lifetime health records.

Area of Science:

  • Health Informatics
  • Computer Science

Background:

  • Internet-based health record management necessitates robust data protection and a standardized format for interoperability across diverse hospital repositories.
  • Challenges include preventing privacy breaches and enabling cooperation among heterogeneous data sources.

Purpose of the Study:

  • To propose a secure multi-agent architecture for accessing healthcare information from multiple, heterogeneous repositories via the Internet.
  • To establish a common healthcare record format for seamless data exchange and management.

Main Methods:

  • A four-tier architecture comprising client applications, central and local access-control systems, and hospital information systems.
  • Integration of eXtensible Markup Language (XML) and Role-Based Access Control (RBAC) for repository management, access control, data exchange, authentication, integrity, and encryption.
