Nowadays, the success of internet technology, made our life very much easy and convenient. But the major problem is to secure the data from duplication and unauthorized use. So the digital watermarking is used. With this technology, we embed the secret information into the actual information for protecting it from unauthorized use. By using this technique only authorized user can access the data. The available methods till data result in good PSNR but they are not secure image. “Steganography” is a technique that thwarts unauthorized users to have access to the crucial data, to invisibility and payload capacity using the different technique like discrete cosine transform (DCT) and discrete wavelet transform (DWT).The available methods till date result in good robustness but they are not independent of file format. The aim of this research work is to develop independent of file format and secure hiding data scheme. Accordingly an efficient scheme is developed with the combine watermarking and steganography technique.
