摘要：Watermarking adva nces have conveyed efficient developments in health management system. An enormous volume of medical information is to be proficiently stored, retrieved, and circulated. This has led to the amplified security threats that have to be addressed explicitly. In this paper legitimacy of the patient and reliability of the medical image is maintained while circulating images over internet. Patient details and image information are converted to message digest using Secure Hash Algorithm (SHA). Advanced Encryption Standard (AES) is then applied to generate encrypted authentication code. Generated code is implanted using Discrete Cosine Transform (DCT) methodology. Embedding of authentication code certifies image veracity with respect to a specific patient. Analysis of quantitative parameters reveals the effectiveness of the proposed approach
