A novel DWT-SVD based stenographic technique is presented. A QR-code payload guides the alternation of the singular-values of DWT blocks. This method can be used by smart phones, smart video-cameras for business and consumer applications. This method has high PSNR and SSIM and survived chi-square test with 100% message recovery.
Islam REF used DWT-SVD to conceal a QR barcode in a carrier image with 100% message recovery.
