Abstract

In the Digital Age, All Data used in the Internet is Digitized and Transmitted and Received Over a Communications Network. Therefore, it is Important to Transmit Data with Confidentiality and Integrity, Since Digital Data may be Tampered with and Tampered by Illegal users. Steganography is an Efficient Method for Ensuring Confidentiality and Integrity Together with Encryption Techniques. I Propose a Hangul Steganography Method that Inserts a Secret Message based on a Changing Insertion Position and a Changing Eojeol Size in a Cover Medium. Considering the Insertion Capacity of 3.35% and the File Size Change of 0.4% in Hangul Text Steganography, Experimental Results Show that the Jaro_score Value needs to be Maintained at 0.946.

디지털 시대에 인터넷에서 사용되는 모든 데이터는 디지털화되어 통신 네트워크를 통해 송신 및 수신된다. 따라서 디지털 데이터가 불법적인 사용자에 의해 변조되고 조작될 수 있기 때문에 기밀성과 무결성을 갖춘 암호화된 데이터를 전송하는 것이 중요하다. 스테가노그래피는 암호화 기법과 혼합되어 기밀성과 무결성을 함께 보장하기 위한 효율적인 방법이다. 커버 매체에 삽입되는 위치와 변화하는 어절 형태를 기반으로 비밀 메시지를 삽입하는 한글 텍스트 스테가노그래피 방법을 제안한다. 한글 텍스트 스테가노그래피에서 3.35%의 삽입용량과 0.4%의 파일 크기 변화를 고려할 때 실험결과는 Jaro_score 값이 0.946으로 유지할 필요가 있다는 것을 보여준다.
