Abstract

The invention discloses a method for quickly embedding and extracting information for protecting, distributing and tracking a WORD document, which comprises a first WORD document, first re-embedded information and distributing and tracking embedded information, and is characterized in that the first WORD document is processed by the first re-embedded information to form a copyright protection document; Wherein the distribution tracking embedded information comprises multiple pieces of embedded information, and the multiple pieces of embedded information are used for carrying out information embedding on the copyright protection document to form multiple embedding and confirm a distribution tracking sender and a purchaser; forward and reverse processing are carried out on the first WORD document through an embedding method and an extracting method, namely, carrying out reverse processing on the embedding method through the extracting method; The invention provides a simple, quick and effective method for quickly embedding and extracting information for protecting, distributing and tracking a WORD document, wherein the method is used for hiding multiple pieces of information.

Description

Technical field [0001] The present invention relates to the technical field of information hiding. More specifically, it relates to a method for quickly embedding and extracting information used for WORD document protection and distribution tracking. Background technique [0002] Microsoft Office Word is a word processor application of Microsoft Corporation, which is mainly used to organize documents, edit and send e-mails, edit and process web pages, and so on. The main features of Word documents are as follows: 1) What you see is what you get. The user uses the Word software to compile documents, so that the printing effect is clear on the screen; 2) Intuitive operation interface. The Word software has a friendly interface and provides a variety of tools. You can use the mouse to complete operations such as selection and typesetting; 3) Multimedia mixing. With Word software, you can edit text graphics, images, sounds, animations, and insert information produced by other softw...
