The Data Capsule model offers a user-centric, self-enforcing approach to personal data privacy by integrating Attribute-Based Encryption with W3C Self-Sovereign Identity standards and Hyperledger Indy blockchain. This framework enables granular control over data sharing, making access policies transparent and cryptographically enforced without requiring continuous data owner involvement.
Key insights
- Data access policies can be bundled directly with encrypted data in a self-contained unit, enabling cryptographic enforcement without continuous external involvement.
- Integrating Attribute-Based Encryption with Decentralized Identifiers and Verifiable Credentials allows for granular data access control while maintaining user-centric identity.
- Utilizing a public, permissioned blockchain like Hyperledger Indy can provide transparency and immutability for published access policies, fostering trust in semi-trusted environments.
