Abstract
A computer-implemented method for validating ownership of a digital asset is disclosed. The computer-implemented method includes transmitting a public key for encrypting a digital asset to an owner of the digital asset responsive to receiving a request for the public key. The computer-implemented method further includes receiving from the owner of the digital asset, an encrypted digital asset and a first liveness hash, wherein the digital asset is encrypted using the public key, and the first liveness hash is generated based, at least in part, on the digital asset in an unencrypted form and a first nonce. The computer-implemented method further includes determining whether the first liveness hash is valid. The computer-implemented method further includes generating in response to determining that the first liveness hash is valid, a digital asset record, wherein the digital asset record includes the encrypted digital asset and the first liveness hash.
