In the advanced growth of Internet, sharing a medical data securely to the required network has never been an easier task. Data communication with large number of patients in hospitals must take into account several issues, including data integrity, efficiency, security and privacy of data owner. The proposed Data Management System, aimed at preventing the modification of data in Hospitals. This project work proposes a blind watermarking algorithm for embedding and transferring a medical data securely over the required network. The high capacity watermarking scheme mostly preferred in telemedicine application. The text Watermarking embedded into YCBCR (Y- luma component, CB –blue difference, CR- red difference) color channels of each medical video frame using Discrete Wavelet Transform and Principle Component Analysis.It also includes the electronic records of the patient with three different sizes and around 146 characters will be embedded into medical video frame. The proposed scheme is imperceptibility, robust, secure and it has good performance compared with previous data management systems. In this project work, privacy and security problem is attended and the problem can be rectified by the way of” Hiding a Data into a Live Video”.
