Abstract

The invention provides a document content protection identification item embedding method and device, and the method comprises the steps: searching all objects in a document file, and searching a graphic object and an image object in the document file; respectively reading attributes of the graphic object and the image object; generating a string of ciphertext keys; and respectively writing the ciphertext key into the attributes of the graphic object and the image object, and storing and packaging to form a protection identification item. The method and device have the beneficial effects thatin the document needing to reserve creator information or to be protected, the attribute of the graphic object or the image object is assigned, and the protection identification item is embedded, so that the document is not easily found by a user in the circulation process, the protection identification item is not easily deleted, and the document is protected. Therefore, it is guaranteed that theprotection identification item is attached to the document, the possibility that the document is maliciously modified is reduced, and the protection identification item is removed.

Description

Technical field[0001]The present invention relates to the field of content protection, in particular to a method and device for embedding protection identification items of document content.Background technique[0002]The current document files need to embed protection identification items, and generally adopt obvious watermarks or insert explicit pictures, so that users can intuitively see the information of the content maker. However, users can easily delete this information and use the file again. The embedded protection identification item is easy to read or modify, which is not conducive to further protecting the document or retaining the creator information.Summary of the invention[0003]The technical problem to be solved by the present invention is to provide a method, device, computer equipment and storage medium for embedding protection identification items of document content, aiming at preventing the protection content items of the document from being modified.[0004]In order...
