“Message Concealment Techniques using Image based Steganography”
Farhan Khan and Adnan Abdul-Aziz Gutub
— Image based steganography is the most popular method for message concealment.
In this paper, two techniques are proposed for enhancing the message secrecy
using image based steganography. The first technique is based on the use of
punctuation marks to encode a secret message before embedding it into the image
file. The second technique is based on the use of modified scytale cipher to
hide a secret message in an image file. Both of these techniques have been
implemented and tested using the S-Tools software package. The original and
stego-images both are shown for the purpose of comparison.
