Steganography and cryptography are two different technical approaches preferred to meet data security over the communication network. Due to the increase of illegal hacking, information security needs alerts in high volume. With the growth of communications based on the internet, computer networks need specialized security which would be available to secure incoming broadcast messages from any threat producing hacker affecting data privacy and also ban access illegally. The process of transferring the secret data without letting the attackers know. It is the method of transporting the secret message without grabbing the notice of attackers. ‘Stegano’ and ‘graphy’ are two Greek words that mean ‘Covered’ and ‘Writing’ respectively it is beneficial for hiding the message, thus protecting it.
