On the basis of copyright description language ODRL 2. 0, a novel asset copyright protection license model for digital printing business was proposed; a digital print copyright protection model was designed based on ODRL 2 license. ODRL 2 core model, abstract model, remedy model and XML encoding was analyzed, and a license instance and the XML encoding suitable for digital printing business was provided. The defects and deficiencies in existing asset copyright protection model were analyzed, and an application-oriented expansion and advanced model focus on the license file was proposed. The model expanded the original copyright protection model, improved usability and security.
