Types of Steganography for Secure Data Maintenance

Abstract

The term steganography is derived from Greek words, where, Stegano(means hiding) and graph (means write).Steganography is a methodology used to encode one secret information into other information, in simple terms it is enclosed by the other messages. It helps to hide private information inside text, audio, image or video. Here, we will discuss various types of Steganography techniques. Steganography is suited to secure the data. In Cryptography, sender encode the information by using encryption key and send it to receiver, if receiver know the key then only it can decrypt the message, whereas Steganography will hide the presence of the communication.
