Content markup method and system for digital work

Abstract

The invention discloses a content markup method and system for a digital work. The content markup method and system for the digital work can enhance the ability of a work owner to mark up the content of the work based on inseparability of hybrid encoding of encrypted content and unencrypted content, and meanwhile the content distribution capacity and user-interface friendliness under an illegal authorization condition can be enhanced and improved. According to the technical scheme, a content processing terminal encrypts a specific digital work and performs hybrid encoding on the specific digital work and unencrypted digital content with markup information according to a certain rule, and then a composite digital work file in a specific format is generated. The composite digital work file can be used for being distributed to a user and being used through a client terminal, and the client terminal judges whether the user obtains legal use authorization of the specific digital work through a judging device or not. If the judgment result is positive, the specific encrypted digital work in the composite digital work file is decrypted and then the decrypted digital work is given to the user to be used; otherwise, the client terminal only sends the unencrypted digital content in the composite digital work file to the user to be used. The content markup method and system for the digital work are applied to distribution and operation fields of digital works.
