With the development of communication technologies,importance of privacy and intellectual property has increased.Therefore, protecting private information during digital communication has become an important issue.
Steganography, which is the science and the art of communicating in a hidden way, provides tools for protection of the private information, which will be embedded in digital signals such as audio and video . Information hiding techniques have been used for covered information exchange over communication networks. The access restricted ID applications in SIS[1] become more popular day-by-day including Geographic Information Systems and Defence Information Systems. Due to the increase in information exchange over communication networks, information security has become an important issue that needs to be considered. Although it is difficult and time consuming to produce and exchange SIS data in digital form, it is very easy for unauthorized users to access and obtain them over the communication networks.

隨著通訊技術的發展，隱私和智慧財產權變的越來越重要。因此，當在通訊時如何保護私人訊息變成首要的議題。資訊隱藏，也就是通訊時如何隱藏訊息的科技與藝術，提供了這樣的工具來保護私人訊息，隱藏在數位信號 如:圖像或音訊檔裡。在通訊網路裡資訊隱藏技術被用來掩護訊息交換的。SIS裡應用通過的限制ID變的越來越受歡迎也包括了 地理學訊息系統與防護訊息系統。有鑑於越來越多在通訊網路上的資訊交換，資訊安全也變成非常重要的議題。雖然
轉換SIS資料成為數位信號很複雜且費時，但是卻很容易在通訊網路上被非授權使用者通過並取得那些轉換過的資料。
