Abstract

In this paper, we propose a robust multi-watermarking method based on vector quantization using an index transform function. In contrast with the conventional watermark embedding methods to embed only one watermark at a time into the original image, we present a method to embed multiple watermarks for copyright protection. The proposed method efficiently enhances the robustness by index transform function which minimizes changes of vector quantization indices against various attacks. Experimental results show that the proposed method has a good robustness against various attacks compared with the conventional multi-watermarking method based on vector quantization.

본 논문에서는 인덱스 변환 함수를 이용한 벡터양자화 기반의 견고한 다중 워터마킹 방법을 제안한다. 기존의 워터마크 삽입 방법들은 단지 하나의 워터마크를 원영상에 삽입하는데 비해 제안한 방법에서는 저작권 보호를 위하여 여러 개의 워터마크를 삽입한다. 제안한 방법은 다양한 공격에서도 벡터양자화 인덱스들의 변화를 최소화시키는 인덱스 변환 함수를 사용하여 견고성을 효과적으로 개선시킨다. 실험을 통하여 제안한 방법이 기존의 벡터양자화 기반의 다중 워터마킹 방법과 비교하여 다양한 공격에서도 견고성이 우수함을 확인하였다.
