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
