Abstract

Recently, according to the product variety of multimedia content some problems are occurred as like an illegal copying, an illegal distribution and a copyright infringement etc. So, for the solution of these problems, some methods were proposed as like watermarking which inserts the information of copyright to the content and the cipher for authentication to DRM which prevents an illegal copying using RSA. In this paper, the multimedia fingerprint based on BIBD code is inserted to the bit-plane of the image content for DRM with RSA, and while the decoding processing. The experiment is operated with the consideration of the image transmission and the transformation. As a result it confirmed that the multimedia fingerprint code inserted in image is detected 60% upper at AWGN 7dB and detected completely 100% at AWGN 10dB upper on PSNR 30, 40, 70 and 80 of Stirmark attacks.

최근에, 다양한 멀티미디어 콘텐츠 제작에 따라, 불법복제, 불법배포 및 저작권 침해 등과 같은 문제들이 야기되고 있다. 이러한 문제를 해결하기 위하여, 콘텐츠에 저적권 정보를 삽입하는 워터마킹과 RSA를 이용하여 불법복제를 방지하는 DRM에 인증을 위한 암호화하는 방법들이 제안되었다. 본 논문에서는, BIBD코드 기반의 멀티미디어 핑거프린트를 RSA의 DRM을 위하여 영상콘텐츠의 비트플랜에 삽입하고, 디코딩 처리에서 영상전송과 변환을 고려하여 실험을 하였다. 실험결과, Stirmark 공격의 PSNR 30, 40, 70 그리고 80에서, 영상에 삽입된 멀티미디어 핑거프린트 코드가 AWGN 7dB에서 60% 이상 검출되었으며, AWGN 10dB 이상에서는 100%의 완전함을 확인하였다.
