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 timestamp indicating a time at which an update to a text segment within the textual content is performed to provide an updated text segment; generating, by the computing device, a unique identifier (ID) based on the timestamp and copyright information associated with the textual content, wherein the timestamp, the textual content, the updated text segment, and the copyright information are recorded on a blockchain of a blockchain network; and embedding, by the computing device, the unique ID in at least a portion of the updated text segment to provide an information-embedded updated text segment that enables retrieval of the copyright information associated with the updated text segment from the blockchain based on the unique ID.
