Patent attributes
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for identifying copyrighted material based on embedded copyright information. One of the methods includes generating, by a computing device, a unique identifier (ID) based on copyright information associated with the textual content, wherein the text and the copyright information are recorded on a blockchain of a blockchain network; adding, by the computing device, one or more function words to the textual content without altering a meaning of the textual content; and embedding, by the computing device, the unique ID in the function words to produce an information-embedded textual content that enables retrieval of the copyright information from the blockchain based on the unique ID.
