In the last decades, Internet becomes more and more popular. Considering the ownership right of digital image, content provides want to devise and effective way to protect their intelligent property right. Digital watermarking, which protects legal copy and distribution of digital products, has been the hotspot of international academia. In this paper, we propose a dual pyramid watermarking method to protect the ownership right of JPEG-2000 image. Dual pyramid watermarking includes a robust pyramid watermark and a fragile pyramid watermark. The robust pyramid watermark is embedded into the host image by changing the wavelet coefficients according to the characteristics of DWT, ROI, and EBCOT to protect copyrights. The fragile pyramid watermark records the characteristics of the coefficients in the high-high band to detect slight changes and authenticate the owner of the images. This scheme integrates the watermarking process with the JPEG-2000 compression procedures. We are able to anticipate which of the transformed coefficients will be discarded by the compression scheme. Experimental results show that the proposed technique successfully survives JPEG-2000 compression and can detect modification of the host image.
