Abstract :
Digital medical images are very easy to be modified for illegal purposes. For example malignant nodules on lung parenchyma in chest CT scan images is an important diagnostic clue, and it can be wiped of intentionally for insurance purposes or added intentionally into chest CT scan images. In this paper we propose multiple watermarking method for authentication of medical images. CT scan images have been chosen for testing the algorithm. In order to achieve high imperceptibility, data embedding technique based on adaptive data hiding method in wavelet domain has been implemented. Experimental results show that the proposed scheme outperforms the prior works in terms of PSNR and MSE.
