In the modern technological world, where data or image transfer through the internet has gained utmost importance, security of the data has become a major issue. The authors use cryptography for the security of the above mentioned data. By the help of cryptography, they convert plain text into cipher text, or data that is unreadable to the attacker. Another approach is to hide data in image and then send it to the receiver. This is known as steganography. Various approaches of steganography have been discovered earlier, which includes changing of data in pixels with the data that the sender needs to send.
