Message Concealment Techniques using Image based Steganography
Farhan Khan and Adnan Gutub
Abstract—
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.
