Example Embodiment

[0053] The embodiments described herein provide methods, systems, and devices associated with an ecosystem for decentralized identity management that can provide entities with unique and verifiable identities. An entity's decentralized identification (DID) may allow the entity to gain complete control of its identity and the information associated with the identity. For example, the entity can be a business entity with many users or one of the users. A verifiable statement (VC) can allow authorization, endorsement and confirmation between different entities. In a business environment, service or product providers can use their customers' decentralized logos and verifiable claims to identify and authenticate customers, and provide services or products accordingly.

[0054] In some embodiments, the decentralized identifier may be a unique identifier indicating the mapping relationship between the real entity and the online entity. The decentralized identification may include a UR...

Abstract

The invention provides a method, system, and device for blockchain based cross entity certification. The device comprises computer program encoded in a computer storage medium. The method comprises the following steps: obtaining, from a blockchain, a blockchain transaction including an authentication request of a first entity for authenticating a user, the authentication request including a decentralized identifier (DID) of the user; in response to determining that the first entity is allowed to access authentication information of the user endorsed by a second entity, obtaining an authentication result of the second entity to the user in response to the obtained blockchain transaction, the authentication result being associated with the decentralized identifier; generating different blockchain transactions including the authentication result; and sending the different blockchain transactions to blockchain nodes so as to add the different blockchain transactions to the blockchain.
