• To present architectural components for a secure, blockchain-based platform for medical record integration.
• To enable patient-centric data retrieval with structured access rules.

Main Methods:

• Integration of blockchain technology and scalable data lakes.
• Development of system routines for secure access to confidential data.
• Implementation of a structured format for composing granular access rules.

Main Results:

• Essential architectural components for secure medical record integration are defined.
• A patient-centric data retrieval approach is presented.
• The system design addresses privacy concerns and regulatory compliance.

Conclusions:

• The proposed blockchain platform facilitates secure medical record sharing for personalized European healthcare.
• The design ensures data privacy through granular access control and adherence to GDPR.
• This approach supports secure information management and patient empowerment.
