dc.description.abstractAbstract ⎯ Steganography (from the Greek for "covered writing") is the secret transmission of a message. Its main distinction from encryption relies on the capacity of making a message altogether invisible. A steganographic message may also be encrypted, for extra security in the case of interception but it actually may not be needed. Steganography has an advantage, it becomes difficult to decipher more than encrypted messages even for a talented code-cracker, simply because it cannot decipher a message since it doesn’t know it is there. This is when steganalysis come into place by detecting a hidden message in an image and identifying the algorithms employed in order to view these “secrets”. We describe different steganography tools, how they work and examine which are more susceptible to be detected when analyzed. Key Terms ⎯ Least Significant Bit (LSB), Steganography, Steganalysis, Stegogramme.en_US
