Area of Science:

  • Health Informatics
  • Computer Science
  • Network Security

Background:

  • Current local and enterprise health information systems lack cross-organizational secure access capabilities for distributed patient data.
  • Existing secure platforms are predominantly local or regional, limiting broader data sharing.
  • Health care commonly utilizes point-to-point communication and internet-based portals, which have limitations in secure, distributed access.

Purpose of the Study:

  • To define an enhanced cross-security platform enabling secure communication and interoperability between diverse health information systems.
  • To propose models for interconnecting regional and national security domains for seamless data exchange.
  • To support both predefined and ad-hoc dynamic access to distributed electronic health records (EHRs).

Main Methods:

Related Experiment Videos

  • Development of an enhanced cross-security platform utilizing a cross-platform zone to interconnect security domains.
  • Exploration of an evolutionary model employing cross-domain security and interoperability services.
  • Discussion of a revolutionary model based on peer-to-peer Grid-like networks and dynamic security credentials.
  • Leveraging the internet as a connective element between disparate security domains.

Main Results:

  • The proposed platform facilitates secure communication and interoperability between different local, regional, and national health information systems.
  • The evolutionary model effectively interconnects security domains through a cross-platform zone, enhancing data sharing capabilities.
  • The platform supports flexible access to distributed EHRs, accommodating both planned and spontaneous data retrieval.

Conclusions:

  • The enhanced cross-security platform provides a viable solution for secure and interoperable sharing of distributed patient information across organizational boundaries.
  • The proposed models offer pathways for evolving secure health data exchange infrastructure, from evolutionary domain interconnection to revolutionary peer-to-peer networks.
  • Securely accessing and sharing electronic health records (EHRs) is crucial for improving healthcare delivery and requires robust, adaptable platforms.
