Biological systems have been a rich source of stimulation for computer security specialists. A wide number of approaches have been proposed over the last decade for encoding data using deoxyribonucleic acid (DNA), giving rise to the developing area of DNA data hiding. In this work, a new data hiding technique based upon DNA characteristic have been developed. DNA matrix has been used to represent the secret message. After that DNA matrix converted to QR (Quick Response) representation that offers a broad scope of practical usage. In addition, we embed the QR codes into the cover image by applying the Haar Wavelet technique on the resulting DNA signals and LSB. Experimental results have presented a high PSNR which indicate a high level of quality in stego image with high capacity.
