Java 2.0 and MATLAB R2009a are the programming tools used to implement the proposed
method. Standard 24 bit cover images of size 256 x 256 such as Lena, Baboon, Gandhi and
Temple were used. Fig. 5 shows the secret image and Fig 6a-6d shows the cover image Lena
and its histogram of RGB channels before distortion. Fig 6e-6h shows the stego image Lena and
its histogram of RGB channels after distortion using Least Significant Bit embedding technique.
Fig 6i-6l shows the stego image Lena and its histogram of RGB channels after distortion using
Matrix embedding technique. Similarly, Fig.7,Fig.8 and Fig.9 shows the results for the cover
image Baboon, Gandhi and Temple respectively. PSNR and embedding Capacity are the metrics
taken here to consolidate the strength of proposed method. Histogram of the stego image shows
that the distortion between cover and stego image is minimum. Interpixel difference coding is
