Abstract

Digital images are the most common cover files used for steganography. In this paper , a new steganography method called JMQT based on modified quantization table is proposed. This steganography method is compared with steganography method JPEG-JSteg. Two performance parameters namely capacity and stego size has been compared. As a result capacity increases and stego size increases. So JMQT provides better capacity and JPEG-JSteg provides better stego-size.

Key Words   
Steganography,data hiding, capacity, imperceptibility, chrominance, luminance, stego image
