In the advanced growth of Internet, sharing a medical data securely to the required network has never been easier task. The proposed Data Management system, aimed at preventing the modification of data in Hospitals. With the rapid growth of Internet and networks technique, multimedia data transforming and sharing is common to many people. Multimedia data is easily copied and modified. This paper proposed a blind watermarking algorithm for embedding and transferring a medical data securely over the required network. This work insisted with a “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. This paper also details the way in which the watermark includes the electronic records of the patient arrived into the hospital with three different sizes and around 146 characters will be embedded into medical video frame. It is in general that high capacity watermarking scheme mostly preferred in telemedicine application. In this project work, privacy and security problem is attended and the problem can be rectified by the way of embedding a data into a specific video. The proposed scheme is imperceptibility, robust, secure and it has good performance compared with previous data management systems.
