A method includes generating, by a computing device, a unique identifier (ID) based on copyright information associated with the digital content, wherein the copyright information and the digital content are recorded on a blockchain of a blockchain network; identifying, by the computing device, one or more attributes associated with a table; embedding, by the computing device, the unique ID in the table by changing one or more attributes associated with the table to be representative of the unique ID, wherein the embedding produces an information-embedded table that enables retrieval of the copyright information from the blockchain based on the unique ID, and wherein a visual difference between the table and the information-embedded table is not apparent to an unaided human eye; allocating, by the computer device, the digital content to the information-embedded table; and distributing the information-embedded table allocated with the digital content to the blockchain network.
