Image watermarking deals with content authentication and proof of ownership. It has been used in our research as a part of application in telemedicine of health care field. Implementation has been carried out to authorize any medical image report being supervised by particular medical supervisor as a sign of a valid treatment and therapy. In case of image watermarking, two images are overlapped in such a way that one act as a cover image and the other one as a watermark itself. A number of transformations are utilized for implementation of image watermarking like wavelet transform, curvelet transform, Contourlet transform, Ridgelet transform etc. The method is chosen as per its own characteristics and advantages. Here, in this paper, we have implemented the watermarking of the medical images using Curvelet Transform and the results are compared with those obtained by Wavelet Transformation implementation on to the same images. Also, the results of software implementation carried out on MATLAB computation platforms are discussed.
