The art of storing the data has got much consideration in the ongoing years as security of digital data has got a major concern in this age of internet. As sharing of sensitive and important data through a typical communication channel has turned out to be unavoidable, Steganography which is a part of concealing data has got a major consideration. Nowadays we are enclosed by various communication forms, where individuals of different types are transmitting data as honest as a entering credit card number to an online-store and as treacherous as a terrorist to plan a hijack. Steganography derives from the Greek word steganos, meaning covered or secret, and graphy (writing or drawing) [1]. Steganography is a technique where data compression, data hypothesis, spread spectrum, and cryptography advancements techniques are united to fulfill the requirement for security on the Internet. This paper is aimed to analyze the different procedures utilized in steganography and to distinguish zones in which this procedure can be connected, with the goal that mankind can be profited.

Keywords: Digital data, Steganography, Spread spectrum, Cryptography
