The personal internetworked notary and guardian

Area of Science:

• Health Informatics
• Computer Science
• Cryptography

Background:

• Lifelong personal medical record systems are crucial for continuous healthcare.
• Existing systems often lack patient control, data privacy, and interoperability.
• Secure and scalable infrastructure is needed to manage sensitive health information.

Purpose of the Study:

• To propose a secure, distributed, and scalable infrastructure for lifelong personal medical records.
• To empower patients with full control over their medical data while ensuring privacy.
• To facilitate authorized data access for healthcare professionals and researchers.

Main Methods:

• Leveraging web technologies and public-key cryptography for a secure architecture.
• Organizing medical data as a tree of encrypted, plain-text XML files for platform independence and durability.
• Implementing a role-based authorization scheme for granular access control.

Main Results:

• A robust architecture enabling patient control and data privacy was designed.
• The system ensures data durability and platform independence through encrypted XML files.
• A role-based access control mechanism was established for authorized data sharing.

Conclusions:

• The proposed infrastructure offers a secure and scalable solution for lifelong personal medical records.
• Patients can maintain control over their health data, enhancing privacy and trust.
• The system supports authorized data access, improving healthcare coordination and research capabilities.
