The advanced healthcare system needs to share electronic patient record (EPR) among different hospitals and specialists for better and easy treatment of patient. However, the protection of the EPR from unauthorized access and malicious attacks is primary concern to preserve the privacy and proper diagnosis. Medical image watermarking in E-health care system is a suitable technique for safety and confidentiality of EPR. In this paper the medical image is separated into region of interest (ROI) and region of non interest (RONI) part, subsequently additive encryption technique is applied to embed patient record into ROI part of cover media. Backup of original information is embedded into RONI part for tamper detection. Thereafter visible hospital logo is embedded into watermarked medical image for identification purpose. Result of this algorithm tested over few medical images and that produces effectiveness of data payload and integrity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
