Application: Verifiable attribute maps (Patent ID: US20240104229A1)
The patent filed by Microsoft Corp. discloses a system for maintaining verifiable attribute maps that store references to identities and associated attribute information. The system utilizes a ledger database to provide tamper-resistant capabilities, generating digests representative of the database state for validation. The system allows for updating attribute information, associating attributes with user identities, and providing access based on verification of the database integrity.
The system involves receiving requests from computing devices to update or access attribute information, validating the database based on digests, and providing access accordingly. The method includes steps such as associating attributes with user identities, generating digests, and verifying users based on the attribute map. The attribute map can be signed by private keys corresponding to public keys of entities, ensuring secure access to data protected by security policies. The validation process involves hierarchical hash data structures and root hash values, ensuring the integrity of the database. Additionally, the system allows for the removal of attributes from the attribute map, updating digests, and providing access to entities.
