Abstract

We are required to adequately adjust the distributed contents to each device and users' demands on the network and to obtain authentication of ownership for our information to prevent the illegal usage of our digital information by non-owners. In this paper, we propose scalable digital watermarking of contents within a compression domain based on Orthogonal Forward Wavelet Transforms, and the proposed method focuses on robust watermark algorithms that are not visually recognizable to embedded ownership information. Therefore, it proposes a watermark insertion methods based on spread spectrum techniques and Provides a watermark key. As a result, it not only extracted the contained watermark from the intentionally altered images, but also secured the watermark information extraction from partial images and ensure the decrease of BER (Bit Error Rate) in the images containing watermarks even when more watermark inserted images are transmitted.

네트워크 상에서 각 장치와 사용자들의 요구 사항에 분산 컨텐츠를 적절히 맞출 필요성이 요구되고 있고, 디지털 정보의 비소유권자의 불법적인 조작 방지 및 변형이 가해진 정보에 대해 자신의 소유권을 인증할 필요성이 제시되고 있다. 본 논문에서는 내장한 소유권 정보를 시각적으로 인식할 수 없는 강인한 워터마크 알고리즘에 중점을 두고, 직교 웨이브릿 변환을 기반으로 한 압축 영역에서 컨텐츠의 다중 계층 디지털 워터마킹 기법을 제안한다. 또한 대역 확산 기법을 기반으로 한 워터마크 내장 방법을 제시하고 워터마크 키를 생성한다. 실험 결과, 고의적인 영상의 변형에서 내장된 워터마크를 추출할 뿐만 아니라 영상의 부분적인 영역에서도 워터마크의 정보 추출을 보장하고, 워터마크가 내장된 영상의 정보를 더 많이 전송 받을수록 워터마크가 내장된 영상에 나타나는 BER(Bit Error Rate)의 감소를 보장한다.
