Steganography :-

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.

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.
