More Information
Summary:Verifiable attribute maps that maintain references to identities and attribute information associated with the identities are disclosed. A verifiable attribute map is maintained by a ledger database that provides tamper-resistant/evident capabilities for tables (comprising the map) thereof. For instance, when a materialized view of the database is generated, the database provides a digest representative of a state thereof to computing devices that access the map for the attribute information. When the database receives a request from a device to access the map, the digest is received along therewith. The database is validated based on the digest to determine whether the database has been tampered with since the provision of the digest. Responsive to a successful validation, the database provides access in accordance with the request. When attribute information in the map is updated, the database subsequently generates a new digest, which is provided to the computing device.
