Abstract: The technical revolution associated with the implementation and the development of digital technologies in medicine, has led to the emergence and active development of new directions in many areas of medicine. Confidentiality of Electronic Health Record (EHR) and privacy are two important security requirements for healthcare systems. In today’s Internet-connected world, tampering of digital images by malicious users has become very common. This clearly is a direct violation of one’s intellectual property rights, and hence, image protection by resolving rightful ownership is gaining utmost importance. Reversible watermarking (RW) techniques are a potential replacement for conventional watermarking systems, in case if the images to be protected are very sensitive. The source and origin of the medical image and patient related information must be authenticated to verify that it corresponds to the right patient. Hence in this work, protection of medical images and patient related information in healthcare using Chaotic reversible watermarking method is presented. The performance of presented method is evaluated in terms of Mean Absolute Error (MAE) PSNR (Peak Signal to Noise ratio), Normalized Cross Correlation (NCC) and RMSE (Root Mean Square Error).
