In the current scenario, once a patient has been diagnosed with a disease, an expert physician’s opinion is sought forthwith, in accordance with advent of technology, and techniques do come into a key role in medical diagnosis. Most of the patients and physicians prefer to get a viewpoint before proceeding further with procedural treatment plans. Henceforth, securing and transmitting of data plays a vibrant role in terms of accuracy, security and other parameters. Cyber criminals involved in hacking medical data, look at it as an opportunity to hawk these sensitive data, leading to the hour of concern. The augment is to allow the patient information to govern and share, to end parties with at most level of seizure; so that information cannot be leaked. Because Government, International and National Medical Associations are looking at medical data security as a priority, it is very important to have an efficient algorithm or a method. The novelty in the proposed work lies in using the patient data as a security protocol and appending three stages of security: bundle encryption generated based on patient ID and age as the first stage, augmentation index derived from bioelectric signal source—photoplethysmograph (PPG)—as a pivotal opener and hybrid discrete wavelet transform–discrete cosine transform (DWT-DCT) watermarking in the second stage, last level of de-watermarking of embedded data from facial photograph of the patient.
