Abstract
This paper proposes an added security feature for medical image application with Prediction Error Expansion (PEE) based Reversible Watermarking (RW) technique. The key (Private) acts as security parameter and the authentication is accomplished through watermarking. This algorithm can be implemented for security of medical images like USG, MRI, CT scan and x-ray. The patient details, diagnosis summary or some other information can be embedded in the above-mentioned medical images to provide security. Doctors or any authorized person can decode the image using private key and identify the feature. The implementation is done in MATLAB and the results are validated. The results obtained are encouraging for the proposed medical image security application.
