The authors present a technique to improve embedding capacity of Image using digital logic in this paper. They have applied digital logic operations on two equal halves of an image row to derive the hidden information. They have also compared the change in image using proposed technique and digital logic gate technique. Change in Image using proposed technique is half or more than that of logic gate technique. Information Hiding for Secure Communication and Copy Right Protection is a highly multidisciplinary area that includes digital image processing, signal processing, communication engineering, physical properties of electronics devices, coding theory, data compression, cryptography and the theory of visual perception.
