Abstract
Data security pays more attention in most of the communication fields. Image steganography is one of the leading data security techniques that provides confidentiality with high embedding capacity and high steganography image quality. This work proposes Discrete Haar Wavelet Transform (DWT-H) and bitwise operations-based embedding technique to embed secret QR-code message in the cover image and extraction of QR-code secret message is also carried out by the same methodology. The efficiency of the proposed method is estimated by Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR). This technique provides less MSE and PSNR in the range of 31dB to 44dB and extracts QR code image up to version 40. The results of the proposed method provide the practical feasibility for QR-coded-based security applications with less time and high accuracy.
