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