A Novel Digital Watermarking Method for Commercial Bills Based on V Systems

The based on the background of anti-counterfeit of commercial bills, a novel digital watermarking method is proposed in this paper. The watermarking algorithm is based on a class of orthogonal function systems-V systems. The experiment results show that the algorithm has better robust than the traditional watermark algorithm. Based on the property of uniformity of the corresponding Fibonacci transformation, the watermarking method has the following advantages: (1) encoding and decoding are very simple and they can be applied in real-time situations. (2) The algorithm can endure severe attacks such as extreme noise levels, very high loss in its data or data packets, or jpeg compression.
