Comparative Analysis of Hybrid Transform Domain Image Steganography Embedding Techniques

Mukta Goel, Rohit Goel

Abstract :

Steganography is an important area of research in recent years involving a number of applications. Image steganography is the art of hiding secret information into a cover image. The modern secure image steganography presents a challenging task of transferring the embedded information to the destination without being detected. Transform domain methods hide messages in insensitive areas of the cover image which makes them more robust to attacks. DCT/DWT is used to transform cover image from spatial domain to frequency domain. The secret image or information is then embedded into the frequency domain coefficients. This paper compares hyid transform domain technique for different methods for embedding secret image into cover image. The algorithms are compared for Peak Signal to Noise Ratio (PSNR) which is a measure of the difference between the cover image and the stego image
