초록

본 논문에서는 인터넷 기반 스트리밍 음악 서비스의 저작권 보호를 위한 새로운 오디오 포렌식마킹 시스템을 제안한다. 제안한 방법에서는 스트리밍 서비스의 QoS 보장을 위해 고속으로 포렌식마크가 삽입된 MP3 파일을 생성한다. 이를 위하여 사전 포렌식마킹 과정을 두고, 사전 처리된 MP3 파일을 프레임 단위 조합 방식으로 사용자 정보가 삽입된 새로운 MP3 파일을 생성한다. 실험 결과, 제안한 방법은 강인성과 비인지성 및 실시간성 등에서 만족스러운 결과를 보였다. 또한 서버/클라이언트로 구현된 스트리밍 기반 오디오 포렌식마킹 시스템에서 실시간 삽입과 모바일 단말에서의 재생과 함께 삽입된 포렌식마크 검출이 가능함을 확인하였다.

In this paper, we propose a new audio forensic marking system for protecting the copyright of the Internet-based music streaming services. In the proposed method, in order to guarantee the QoS of the streaming service, high speed, and generates a forensic mark inserted MP3 file. We make pre-marking process and generate a new forensic marked MP3 file, a combination of the pre-marked MP3 frame, the inserted user information. Experimental results show that the proposed method satisfactory results robustness and imperceptibility, and real-time properties. In addition, we were confirmed that the real-time embedding and detection from the streaming-based audio forensic marking system that has been implemented on the server/client is possible.
