Preserve Robustness for Image Data Hiding

In this paper, we have explained an algorithm for preserving robustness for image data hiding. Robust data hiding is the process of extraction the correct data after compression or any other alteration applied on the embedded image. Embedded image is the image that obtains after hiding some information on the original image. Our technique compare with the existing technique called Y. Q. Shi method. We are comparing results of both techniques, i.e., PSNR of the embedded image and the number of error bits introduced in the extracted data from the embedded image. Both the algorithm is implemented on all kind of images including aerial, texture, and miscellaneous image. It also successfully implemented on the medical image.
