초록

본 논문에서는 모바일 상에서 서비스되는 3D 콘텐츠들의 저작권 보호 및 불법 복제 방지를 위한 워터마킹 기법을 제안한다. 제안한 방법에서는 Buyer-Seller 워터마킹 프로토콜 기반으로 모바일 애니메이션 데이터 내에 저작권 정보 및 사용자의 폰번호를 공간 영역 및 암호화 영역 상에서 각각 삽입한다. 또한 인가된 사용자만 모바일 폰 상에서 3D 애니메이션 게임을 실행하기 위하여 실행키를 실행코드 내에 삽입한다. 본 실험에서는 모바일 애니메이션 저작툴인 G3-SDK 상에서 제안한 방법을 구현하였다. 실험 결과로부터 제안한 방법이 모바일 3D 애니메이션의 저작권 보호 및 불법 복제 방지가 가능함을 확인하였으며, 잡음첨가, 데이터 정밀도 가변, 확대, 축소 등의 공격에 대하여 워터마크가 검출됨을 확인하였다.

This paper presents a watermarking method for copyright protection and illegal copy prevention of mobile 3D contents. The proposed method embeds copyright information and user's phone number into spatial domain and encryption domain of mobile animation data based on Buyer-Seller watermarking protocol. Furthermore, we insert user's operation key so that only authorized user can play 3D animation game in mobile device. We implemented the proposed method by using mobile animation tool, G3-SDK. From experimental results, we verified that the proposed method is capable of copyright protection and illegal copy prevention since the watermark can be well extracted against geometrical attacks, such as noise addition, data accuracy variableness and data up/down scaling.
