US Patent 11714894 Authenticating client applications using an identity fabric blockchain

Methods and apparatuses are described for authenticating client applications using an identity fabric blockchain. A server receives a first registration request from a first client application. The server generates a first decentralized identifier corresponding to the first client application and stores the first identifier in an identity fabric blockchain. The server receives a second registration request from a second client application, generates a second decentralized identifier corresponding to the second client application, and stores the second identifier in the blockchain. The server receives a first authentication request from a first resource and authenticates the first client application based on the first authentication request and the first decentralized identifier stored in the blockchain. The server receives a second authentication request from a second resource and authenticates the second client application based on the second authentication request and the second decentralized identifier stored in the blockchain.
