Abstract:
Steganography is the approach for hiding
any secret message in a variety of multimedia
carriers like text, images, audio or video files.
Whenever hiding a secret message, it is very
important to make it invisible. This paper
proposes a technique to hide Myanmar text
message into BMP image by representing
Myanmar Unicode hexadecimal value of each
character in the secret message. It also
represents each hexadecimal pixel value in the
cover image as a set of separated single
hexadecimal-digit. The technique creates a
matching list from the hexadecimal-digits of the
characters in the secret message with the
hexadecimal-digits of the pixels in the cover
image. The technique compresses the created
matching list to be as small as possible to embed
it in the unused file space at the end of the cover
image file. The results show that this technique
provides security against visual attack because it
does not make any changes in the pixel of the
cover image.
