Copyright protection based on hidden copyright information

A non-transitory, computer-readable storage medium storing one or more instructions executable by a computer system to perform operations for hiding copyright information in printable materials, the operations comprising:

• generating, by a computing device, a unique identifier (ID) based on copyright information associated with digital content, wherein the copyright information and the digital content are recorded on a blockchain of a blockchain network, and wherein the copyright information comprises one or more of a change in copyright ownership associated with the digital content, a modification to the digital content, an update to the digital content, and a change in licensing associated with the digital content;
• determining, by the computing device, one or more features associated with one or more printable materials;
• and
• converting, by the computing device, the unique ID to a digital watermark based on the one or more features;
• and
• printing, to the one or more printable materials, a printed version of the digital content, including printing the digital watermark, the printed digital watermark not being apparent to an unaided human eye, wherein the printed digital watermark enables retrieval of the copyright information from the blockchain based on the unique ID.
