  • 摘要:Based on the self-characteristic of digital watermarking techniques and the multi-statistic theory, this paper makes a research on the watermark autocorrelation detection. First, the setting of detection threshold, the calculating of false alarm probability and missing detection probability are studied. Second, the relationship between the length of watermark, the watermark embedding strength and the attack strength is established. Third, an improved method of watermark generating is proposed to promote the robustness of watermarking algorithms. Finally, the probability of multiple watermark embedding is studied
