  • Method for confirming ownership of digital assets based on hash algorithm and method for tracing to a source of digital assets based on hash algorithm
    Patent number: 12341912
    Abstract: Method for confirming ownership of digital assets based on hash algorithm and method for tracing to a source of digital assets based on hash algorithm are provided. Entities involved in confirming the ownership of digital assets include an original user, a CA authentication center and a digital asset authentication center. The process of confirming the ownership includes generating a one-time CA certificate by the original user, authenticating the digital assets by the digital asset authorization center and the original user, generating an ownership confirming document by the original user, creating a quantum digital signature by a three-party, and the like. The method for tracing includes generating subsidiary documents in real time, constructing a unique identity for a digital asset at an accessing moment, traceability analysis, and so on.
