System and method for issuing verifiable claims

Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for verifiable-claim issuance. One of the methods includes: receiving, from a first entity, a request for creating a verifiable claim (VC) for a decentralized identifier (DID) associated with a second entity; obtaining, in response to receiving the request, a digital signature associated with the firstentity; and generating the VC based on the received request and the obtained digital signature.

Description

technical field [0001] The present application generally relates to methods and devices for managing decentralized identities and verifiable claims based on blockchain technology. Background technique [0002] Traditional identity management systems are based on centralized institutions such as corporate directory services, certification authorities, or domain registrars. Each centralized institution can serve as a root of trust, providing credibility for its endorsed identities. For such systems, data associated with identities is typically stored in centralized databases, if not in traditional information storage media. The identity maintenance of each person or entity is under the control of a centralized authority. By their nature, traditional identity management systems carry the security risks that each centralized institution suffers, and provide inefficient mechanisms to collect identities or credentials provided by different centralized institutions. In such syst...

AI Technical Summary

Problems solved by technology

Identity holders may be required to keep important identity credentials, such as encryption keys, which, when compromised, could expose the identity holder to the risk of identity loss

Furthermore, for business entities that need to manage a large number of user identities, such identity management systems have often proven to be inefficient and user-unfriendly

The mapping between identities managed by such identity management systems and account or service IDs held by business entities is often difficult to maintain

Finally, such identity management systems often require frequent access to and interaction with the blockchain network, which can be expensive and resource consuming
