Digital Watermarking Based on Two-Way Arnold Transform and QR Code
Abstract:
This paper proposes a digital watermarking algorithm based on two-way Arnold transformation and QR code. This algorithm uses the QR barcode as the watermark, and in its pretreatment process it uses the two-way Arnold transformation to broke up the QR code image into blocks which then coded and re-arranged in a specific order. Considering the role of Singular Value Decomposition in watermark embedding, here the watermark information is embedded into the low frequency coefficients of wavelet transform of the carrier image. Simulation results show that the algorithm is robust against attacks such as shearing, the JPEG compression and noise attacking.
