Steganography (pronounced STEHG-uh-NAH-gruhf-ee, from Greek steganos, or "covered," and graphie, or "writing") is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography takes cryptography a step further by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning data will fail to know it contains encrypted data (Neijts and Semilof, 2007). The need to keep sensitive information out of the hands of certain people is growing rapidly and for some organisations, it is becoming more of a necessity than ever with the growing rate of internet communications. This report presents both the general information on steganography and the importance of it. The report shows the need to be able to understand how it works, and the advantages and disadvantages of steganography for companies across the world. Research In modern digital steganography, data is first encrypted by the usual means and then inserted, using a special algorithm, into redundant (that is, provided but unneeded) data that is part of a particular file format such as a JPEG image. Think of all the bits that represent the same colour pixels repeated in a row. By applying the encrypted data to this redundant data in some random or non-conspicuous way, the result will be data that appears to have the "noise" patterns of regular, non-encrypted data. A trademark or other identifying symbol hidden in software code is sometimes known as a
