Abstract

See full text

A blockchain system for ownership verification may include one or more issuer network nodes and one or more verification network nodes. An issuer network node may be configured to receive a request including a public key to issue a credential, provision the credential to the communication device, generate a payload derived from hashing the credential and the public key, store the payload in a record of a blockchain, and synchronize the record to other network nodes on the blockchain. A verification network node may be configured to receive the credential, the public key, and a signature generated by the communication device to request access to a resource, verify the signature using the public key, generate a hash value based on the credential and the public key, determine that the hash value is stored in the blockchain, and authenticate the communication device for access to the requested resource.
