Patient Consent Smart Contracts
Blockchain-based patient consent management system
Patient Consent Management via Smart Contracts
LUMS Final Year Project
Designed and extended a patient-consent prototype using blockchain smart contracts with fine-grained access control. The system focuses on auditability, secure consent updates, and realistic healthcare workflow integration.
Objectives
- Provide patients with granular control over medical data access
- Create immutable audit trail of all consent changes
- Enable secure, transparent consent management in healthcare settings
- Support dynamic consent updates while maintaining security
Technical Implementation
- Smart contract architecture for consent management
- Fine-grained access control mechanisms
- Role-based permissions for healthcare providers
- Audit logging and transparency features
- Integration considerations for clinical workflows
Key Features
- Granular Control: Patients can specify exactly which data types each provider can access
- Auditability: Complete history of who accessed what data and when
- Dynamic Updates: Patients can revoke or modify consent at any time
- Secure Updates: Cryptographic verification of consent changes
- Workflow Integration: Designed to fit realistic healthcare provider workflows
