1. A system for managing transactions of content items, comprising:
means for obtaining a request of a first party to process a transaction of a first content item, the first content item comprising a first audio signal;
means for decoding an auxiliary data signal encoded within the first audio signal to extract a digital payload;
means for obtaining an identifier from the digital payload;
means for accessing metadata linked to the first content item by the identifier to determine whether the transaction is authorized; and
means for digitally signing the transaction into a signed message and providing the signed message and address for the transaction to a distributed blockchain registry to register the transaction for the first content item in the distributed blockchain registry.
