Invisible Tool Kit or Stenography - prakashkrishnanhere - 10-04-2017 Description : Steganography is the art and science of writing hidden messages in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message. By contrast, cryptography obscures the meaning of a message, but it does not conceal the fact that there is a message. Today, the term steganography includes the concealment of digital information within computer files. For example, the sender might start with an ordinary-looking image file, then adjust the color of every 100th pixel to correspond to a letter in the alphabet a change so subtle that someone who isn't actively looking for it is unlikely to notice it.
