Research And Design Of A Data Hiding System Based On Text Document

With development of computer hardware and internet technology, KEY of traditional encryption is becoming more and more unsafely. So, many people found Information Hiding Technology is a good solution for information security in some special area.In this paper, research on design an embedding algorithm and implement a information hiding system based on english text document. The main research contents of this paper including:1. Give an introduction about basic conception of information hiding; Introduce three kinds algorithm of information hiding based on text document, and give the advantage and disadvantage.2. Propose an embedding algorithm based on English text document.3. Design and implement the information hiding system based on the embedding algorithm.4. Embed a "block" instead of "0" or "1" to a text object, the result shows it can increase the secret information in the text.5. Did some research on system test.And the experiment result shows this method is feasible and effective.
