  Data hiding has received much attention due to rapid development of internet
and multimedia technologies where security of information is a very important
concern. This is achieved by Steganography, which is the art or science of
hiding data into another data, so that human eyes cannot catch the hidden
information easily. There are many ways to hide information-like inside an
image, text, audio/ video etc. Among them image steganography is a very
attractive research area. The goal is to transmit a data within a modified
image (called stego-image)by minimizing the number of bit flips. In this paper,
a new steganography technique has been proposed using Graphical codes and also
comparison with steganography technique using BCH codes has been studied.
