Abstract
Processing a genuine instance of a digital good using a blockchain including: registering an ownership of the genuine instance using a plurality of transactions, the genuine instance uniquely identified by a content descriptor which is cryptographically linked to an ownership token and includes intrinsic characteristics of the genuine instance, wherein the ownership token includes a token seed and a token signature; validating each transaction of the plurality of transactions by a plurality of validators; and recording that the genuine instance belongs to an owner by recording each transaction of the plurality of transactions in the blockchain once each transaction has been validated.
Claims22
A method for processing a genuine instance of a digital good using a blockchain, the method comprising:
- registering an ownership of the genuine instance using a plurality of transactions, the genuine instance uniquely identified by a content descriptor which is cryptographically linked to an ownership token and includes intrinsic characteristics of the genuine instance,
- wherein the ownership token includes a token seed and a token signature;
- validating each transaction of the plurality of transactions by a plurality of validators;
- and
- recording that the genuine instance belongs to an owner by recording each transaction of the plurality of transactions in the blockchain once each transaction has been validated.
A non-transitory computer-readable storage medium storing a computer program to process a genuine instance of a digital good using a blockchain, the computer program comprising executable instructions that cause a computer to:
- register an ownership of the genuine instance using a plurality of transactions, the genuine instance uniquely identified by a content descriptor which is cryptographically linked to an ownership token and includes intrinsic characteristics of the genuine instance,
- wherein the ownership token includes a token seed and a token signature;
- validate each transaction of the plurality of transactions by a plurality of validators;
- and
- record that the genuine instance belongs to an owner by recording each transaction of the plurality of transactions in the blockchain once each transaction has been validated.
A system for processing a genuine instance of a digital good using a blockchain, the system comprising:
- an issuer configured to register an ownership of the genuine instance using a plurality of transactions, the genuine instance uniquely identified by a content descriptor which is cryptographically linked to an ownership token and includes intrinsic characteristics of the genuine instance,
- wherein the ownership token includes a token seed and a token signature;
- and
- a plurality of validators configured to validate each of the plurality of transactions,
- wherein the genuine instance is recorded as belong to an owner by recording each transaction of the plurality of transactions in the blockchain once each transaction has been validated by the plurality of validators.
