A Public-key Asymmetric Robust Watermarking Algorithm Based on Signal with Special Correlation Characteristic

Year: 2004

Type: article

Abstract: A public-key asymmetric robust watermarking algorithm based on signal with special correlation characteristic \nis proposed in this paper. This algorithm is designed to permit pubic watermark detection while preventing the \nwatermark from being removed without the private keys. A signal, which is pseudorandom sequence with \nspecial auto-correlation characteristic, is used as watermark, and the signal’s characteristic is the foundation of \nthis algorithm. Therefore we first construct the method of generating the pseudorandom sequence and prove its \nauto-correlation characteristic. Then we describe the algorithm in detail. Experiment results show that the \nalgorithm is valid and robust to common signal distortions and malicious attacks.
