The transferring of medical image to the medical practitioner through cloud network with field expects around the globe to get better diagnostics and expect suggestions ever-increasing significantly. Enormous possibility of security treats arises while transferring the medical image through cloud services. In this paper, the trustworthiness, information integrity and authenticity of the patient EMR during storage and transmission over network can be improved without compromising medical quality and diagnosis accuracy. This can be achieved with the help of combined segmentation, cryptography and reversible data hiding on medical images. In this work, we store the patient basic details in the medical image using reversible data hiding with data capacity and security enhancements. The proposed method uses medical images of EMR as cover image, the patient’s details can be encoded in the cover image as data and finally encrypt the image using asymmetric key encryption. The proposed method provides more improvement in integrity, security, authenticity, data capacity and error rate. This method also maintains PSNR value above 51dB.
