Steganography is an art of hiding the information within the files. Sensitive message and information are hided into the multimedia files without being detected by the process of steganography . It allows anonymous and secure interchange of information without being detected easily. The hidden information is not visible with naked eyes and hence the chance of being detected just just by seeing the files containing the hidden information is near to impossible. Steganography can be done with media, files and folders.
Steganography is sometime used as an authentication watermark by the digital music and movie companies which is invisible to the users but is useful to keep the authenticity. Steganography is also used by the terrorist for the secret information exchanging. Many big terrorist organizations use this technique to carry out their information exchange. Steganography is also popular from the forensics point of view and is widely covered under cyber forensics.
