Steganography is the art and science of communicating in a way which hides the existence of the communication. Unlike Cryptography, where the attacker is allowed to detect, intercept, modify messages without being able to violate certain security premises guaranteed by a cryptosystem, the goal of steganographic method is that no one will be able to know whether anything is hidden in the image or not. For hiding secret message in images, there exists a large variety of steganographic techniques. Few of them are more complex than others and all of them have respective merits and demerits. The requirements of steganographic techniques used, differ in accordance with different applications. Based on the PSNR value of each image, the PSNR value of stego image is higher. The proposed algorithm is the combination of random pixel manipulation methods and Least Significant (LSB) matching of Steganography embedding and extracting method.
