Securing Medical Images Using Digital Watermarking
Modern healthcare systems are based on managing diagnostic information of patients in a digital way. To guarantee the security, authenticity and management of medical images and information through storage and distribution, the watermarking techniques are used. Medical image watermarking is an appropriate method used for enhancing security and authentication of medical data. This paper discusses the available medical image watermarking methods for protecting and authenticating medical data. As a lossless technique, the original image can be perfectly recovered by performing the reverse process of the watermark embedding if the watermarked image is intact.
