Abstract: Owing to the expanding benefit for tele-health amenities have developed awareness in the practice of medicinal image protection expertise. It mostly condensed with patient report that are cautious and must only offered to allowable personality. So the medicinal image safety becomes a very great complexity when victim data are fetched through the open system. At first, the secret key of 128 bit size is generated by image histogram and the medical image is encrypted by diffusion and substitution process. Then the secret key is embedded within the cipher image by the process of steganography to obtain key embedded cipher image. At last, the patient details are embedded into the key embedded cipher image and later on, the patient details and the key is extracted. Finally, using the extracted key, decryption operation is performed to get the original image.
