Medical data includes diagnosis results, patient medical data details and recommendation by the doctors. In hospitals these data are considered as a valuable asset and it is stored securely. The Encryption Technique is proposed to secure and store the medical images; this method is done by MATLAB operator. The medical images as CT scan and MRI scan is given as input image, it gets confused and diffused image to obtain an encrypted image. In the encryption process, a single private key is generated which is same for decryption process. This single private key is known only by authorized users where unauthorized parties are prevented from accessing these medical data. The Inverse process of confusion and diffusion is performed to obtain the decrypted image. Then Hash Algorithm is performed at the output of the confused image, Hash cannot apply in the diffused image that is an encrypted image. When applying MD5, 32 digit hexadecimal number is got as output for given image. Hence with the single private key for both encrypted and decrypted image is stored securely by using MATLAB operator.
