Self-Sovereign Identity (SSI) Principles of Consent Management

SSI emphasises a user-centric approach to data sharing, with consent management playing a crucial role. Here are the key principles:

1. Granular Consent: Users can grant fine-grained access to specific data attributes, specifying what information can be shared, with whom, and for what purpose. This goes beyond traditional "all-or-nothing" consent options, offering more control and privacy.

2. Dynamic Consent: Consent is not static. Users can revoke or modify access at any time, even after initially granting it. This empowers them to adapt to changing circumstances or preferences.

3. Contextual Consent: Consent is tied to the specific context of data use. Users can grant access for a limited time, for a particular purpose, or within a specific application. This ensures data is used responsibly and doesn't exceed what's necessary.

4. Verifiable Consent: Consent records are stored securely and are verifiable. This ensures transparency and accountability, allowing users to track how their data is being used and by whom.

5. Consent Fatigue Mitigation: SSI aims to reduce consent fatigue by simplifying consent processes and making them more user-friendly. This could involve clear and concise language, intuitive interfaces, and avoiding repetitive consent requests for similar actions.

6. Consent Revocation & Right to Erasure: Users have the right to revoke consent and request erasure of their data if it's no longer needed for the consented purpose. This empowers users to control their data footprint and ensure its responsible handling.

7. Consent Management Transparency: Users should be informed about how their consent is used, what data is being collected and shared, and their rights regarding data access and modification. This transparency builds trust and fosters informed consent.

8. Interoperable Consent Management: Consent mechanisms should be interoperable across different SSI ecosystems, allowing users to manage their consent consistently regardless of the platform or service they use. This promotes data portability and user control across the healthcare landscape.

9. Consent Management Security: Consent records and management systems must be secure against unauthorized access, modification, or deletion. This ensures the integrity and confidentiality of user consent and protects users from data misuse.

10. Continuous Improvement: The principles of consent management in SSI are evolving as the technology matures and user needs change. Continuous evaluation, feedback mechanisms, and adaptation are crucial to ensure effective and user-centric consent management practices.

By adhering to these principles, SSI can empower individuals to control their health data, ensuring informed consent and responsible data sharing within the healthcare ecosystem.
