Abstract
The interrelated and highly sensitive issues of the medical image are security and privacy. Protecting the privacy and data integrity has to be done without comprising on the structural integrity of the data. The two layers of security are provided by watermarking and encryption. The watermarking is proposed to be implemented using a hybrid approach which encompasses Inter pulse code modulation and Singular Value Decomposition (SVD) techniques. Bit XOR Optimization is used for optimizing the watermarking parameters. The encryption is proposed to be effected using Data Encryption Standard (DES) and Transposition encryption algorithms. H.264 video codec is the most effective video compression standard developed in video industries. H.264 uses more accurate predication algorithms maintain the same quality video at a low bit rate, without compromising the image quality. A Graphical User Interface (GUI) which enables the user to have ease of operation in loading, watermarking, encrypting and also retrieving the original image whenever necessary is also designed. To check the robustness and the integrity of the watermark, different performance parameter
