Abstract: Data hiding techniques can be used for protecting data from unauthorized users. Here, data hiding technique called steganography is used to prevent illegal access of data. We introduced a new method of hiding data in images by randomly selecting pixel position using dihedral function. We have used different window size to hide data and applied variable dihedral function based on the size of variable. The security of this approach lies in the knowledge of window size and the function. The performance of our method was analyzed using Chi-square, RS steganalysis attack and histogram attack. The quality of the image was also preserved and found to be 52 dB.
