【 摘 要 】

The main focus is on enabling, supporting process in the health care industry for implementing a secure, robust and privacy complaint system for the safe distribution and use of medical image. In this paper, a new method that combines image encryption and watermarking technique for safe transaction of medical image is proposed. This method is based on selecting the ROI in the image as the watermark. This portion is encrypted by linear feedback shift register based stream ciphering which is again encrypted by the key generated by Diffie Hellman Algorithm. The encrypted ROI is embedded into the medical image by Spread spectrum technique. The proposed approach proves to be highly secure as two keys are used for encryption and the secret message is spreaded throughout the Medical image.
