Abstract :
Based on a class of orthogonal functions, a novel digital watermarking method is proposed. This method can be used in the anti counterfeit of commercial bills. The experiment results show that the algorithm is more robust than the traditional watermark algorithm. Based on the property of uniformity of the corresponding Fibonacci transformation, the proposed 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, and JPEG compression
