A robust twofold zero-watermarking scheme for secret QR-Code (Quick Response Code) sharing is proposed in order to increase the security of commercial activities on the internet and media.In this paper we will present a twofold scheme for zerowatermarking to be used for copyright protection, implemented in discrete wavelet transform (DWT) as the first fold and discrete cosine transform (DCT) as a second fold for color images in which the visual secret sharing is used to generate unexpanded master and secret shares for the same QR-Code watermark.The experimental results indicate that the proposed scheme is highly robust and the QR-Code can be decodable even after different types of attack being applied.
