Steganography

Steganography

  •             Steganography derived from the Greek word steganos meaning “covered “and the Greek word graphie meaning “writing”. Steganography is the process of hiding of a secret message within an ordinary message and extracting it at its destination.
  •              Anyone else viewing the message will fail to know it contains hidden/encrypted data.
  •              Modern digital Steganography
  •              data is encrypted then inserted and hidden, using a special algorithm which may add and/or modify the contents of the file.
  •              This technique may simply append the data to the file, or disperse it throughout.
  •              Carefully crafted programs apply the encrypted data such that patterns appear normal
