Medical image security and privacy are two issues that are interrelated and highly sensitive. Protecting the privacy and data integrity has to be done without comprising on the structural integrity of the data. Watermarking and encryption have served the purpose of data security for long. In this research work, a dual security approach is employed where watermarking and encryption is used to provide two layers of security. The watermarking is proposed to be implemented using a hybrid approach which encompasses Inter pulse code modulation and Singular Value Decomposition (SVD) techniques. BitXOR 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 same quality video at the low bit rate, without compromising the image quality. A Graphical User Interface (GUI) which enables the user to have ease of operation in loading the image, watermark it, encrypt it and also retrieve the original image whenever necessary is also designed. The robustness and the integrity of the watermark are tested by measuring different performance parameters and subjecting it to various attacks.
