Image watermarking is a signal that is embedded in a image data permanently such that it can be extracted by dewatermarking using some operations for checking the authenticity of data or user. The watermark is inseparable from the host image and it should be robust enough to resist any modifications along with preserving the image quality. In this way the watermarking helps in keeping intellectual properties to be accessible while keeping them permanently water marked. In our proposed work we have focused on watermarking techniques and checked their robustness against environmental distortions during the storage and transmission of watermarked image. In this work we have applied a hybrid SVD-DCT-DWT watermarking approach in gray biomedical image watermarking to develop a robust algorithm against several image attack. We have also compared our algorithm with two different watermarking technique named as DCT-SVD,DWT-DCT.
