Abstract
Digital watermarking is one of solutions to protect intellectual properties and copyright by hiding information, such as a random sequence or a logo, into digital media. This paper deals with a new blind robust watermarking technique for embedding secrete medical information as a watermark in a host image. As a host image a color medical image is used, and a blue plane goes through the DWT. The diagnosis information of the patent is used as a watermark binary image. The embedding process is done in the LL Sub band of the blue plane of the host image, for DWT a bi-orthogonal wavelet filter is used for corresponding. This can be extended for store more than one watermark information in one medical image by embedding the watermark images in the different sub bands of the host image. The resulting watermark is having good PSNR and robust against different attacks.
