Abstract

We present steganographic service model and algorism that fit feature of streaming audio book service in order to hide information of copyright and certificate of it. Secret information is encrypted with random numger by secret key that client and server share, so that increase confidentiality. We made secret data distributed randomly and evenly, and improved throughput by simplifying additional computations considering streaming environment.

본 논문은 오디오 e-Book 스트리밍 콘텐츠에 저작권과 인증과 관련되는 비밀 데이터를 인코딩하고 추출할 수 있도록, 스트리밍 서비스 특성에 적합한 스테가노그래피 서비스 모델과 알고리즘을 제안한다. 은닉 데이터는 송신측과 수신측에서 공유하는 비밀키 k를 사용하여 생성한 의사난수로 암호화하여 안전도를 높였다. 또한 은닉데이터가 커버데이터의 초반 일정구간 안에 랜덤하게 고루 분포하도록 하였고, 스트리밍의 상황을 고려하여 기타의 연산을 단순화하여 처리율을 높였다.
