Abstract:

Embodiments verify a digital asset by a first owner of the digital asset in response to a first transaction with a creator of the digital asset, the first owner having a corresponding first owner private key and a first owner public key. Embodiments receive a first digital record that corresponds to the digital asset. The first digital record includes an initial portion including initial parameters and a creator public key of the creator, and an appended initial digital signature computed using the initial parameters, the creator public key, and a creator private key of the creator. The first portion includes first parameters. Embodiments extract from the first digital record the creator public key, extracts from the first digital record the first digital signature and extracts from the first digital record the initial portion, the initial digital signature, and the first portion.
