An inclusive survey of Steganography and Steganalysis: A Review

Abstract

Steganography is an art of covering the secret data by using different cover files such as text, images, audio, video files etc. Steganography can be combined with cryptography to provide extra security to the data. Steganography is derived from two Greek words: (i) steganos (ii) graphia. Steganos means “covered” and Graphia means “writing”. Cryptography is an art of securing the data from unauthorised access. It is derived from two Greek words: (i) kryptos (ii) graphein. Kryptos means “secret” and Graphein means “study”. Steganalysis is a technique to detect hidden information using Steganography. This is similar to cryptanalysis technique which is used in Cryptography.
