Gray code based data hiding in an image using LSB embedding technique

Abstract

Steganography is a mask to hide a confidential data in the form of normal text file or via audio/video. Even though there are many different types available for data hiding, our main aim is to focus on the digital image steganography because of its demand and availability, where images are in the form of pixels and can be represented in the form of binary. Since technology is developed, hackers also got developed. Therefore the security must be implemented in a better manner. To overcome the hackers, Gray code based technique is used to conceal a text in the digital image and then decrypt it. The proposed algorithm is implemented in MATLAB. This paper point is to transfer a confidential data in best and secure way where no one can recover the private information and also we can differentiate the images by using PSNR and MSE.
