Abstract
Designed and created by Toyota subsidiary Denso Wave, quick response (QR) code has now been commonly used in many suitable applications to deal with real-time data because it can be read quickly by smartphones or tablets. The covering of information is indeed the technique of keeping secret knowledge inside the source media. Two qualities would have a strong approach to data hiding: high consistency of the stego image as well as high potentiality for concealing. In this paper, a redundant discrete wavelet transform (RDWT) domain-based information hiding method using QR code decomposition is proposed. An appropriate cover is torn down by RDWT mechanism, and the private image is concealed within the sub-bands of the factorized QR code. For the purpose of demonstrating the effectiveness of the proposed approach with respect to imperceptibility, capability and robustness to different signal processing assaults, multiple tests and case analysis are conducted.
