Abstract
Steganography is the new scheme in order to hide a secret data in cover images which uses transform domain to increase its robustness and security. transform represents edges better than wavelet, transform offers an effective solution to the problems associated with Image Steganography using wavelets and DCT (Discrete Cosine Transform). In this method size of cover image and secret image is same while in other methods secret image is half the sizes of cover image, also the stego image and extracted images are closer to original image than other methods.
