Abstract

Medical imaging organizations currently face a significant problem with stealing of medical data. Watermarking is a powerful tool that can be used to authorize the hidden information in cover image. The unique features associated with watermarking are authorization and copyright protection. Because of its unique characteristics, watermarking associated with medical data hiding gives more robustness in medical imaging. In spite of this adding security to watermarking in medical imaging, gives more protection for medical information. This paper explored two main fields that, the encryption of medical images using DNA Encoding and Spatiotemporal Chaos Algorithm and the embedding of medical images in cover image using hybrid transformation of NSCT, RDWT and SVD. The goal of this study was to develop a methodology to improve the robustness, imperceptibility and security for medical information without implementing a physical model, thus saving time, money and reducing the risks associated with hacking partners. For this paper, I used patient health document as one watermark and his medical image as another watermark. The theoretical model has demonstrated that it is possible to use this type of technique and apply it to a complex digital image transmission. The correlation observed before and after encryption and embedding procedures. Experimental results show how robustness and imperceptibility and security of medical images are improved.
