Abstract

본 발명은 구조적 멀티패턴 워터마크 생성 장치 및 방법과, 이를 이용한 워터마크 삽입 장치 및 방법, 워터마크 검출 장치 및 방법에 관한 것으로서, 입력되는 사용자 은닉 정보를 복수 개로 분할하고, 복수 개로 분할된 데이터들을 메시지 인코딩(Message Encoding)하며, 메시지 인코딩된 복수 개의 데이터를 영상 신호 형태로 변조하고, 영상의 2차원 이동에 대응하기 위한 동기화 신호를 생성하며, 영상 신호 형태로 변조된 복수 개의 메시지 신호 및 동기화 신호를 이용하여 복수 개의 서브 기저 패턴을 생성하고, 복수 개의 서브 기저 패턴을 이용하여 하나의 단위 워터마크인 구조적 멀티패턴 워터마크를 생성함으로써, 워터마크의 정보 은닉량을 증가시키고, 워터마크의 구조적인 특징으로 인해 영상의 2차원적 이동뿐만 아니라 일반적인 기하학적 변형에도 강인하게 대응할 수 있다.
