A Print-Scan Resilient Watermarking Scheme Based on the Numbers of the DCT Positive and Negative Coefficients

摘要：

　　Copyright protection has drawn much attentions especially in the advent of computer and the intemet.Illagal copying of digital multimedia has been much easier because of widely using of the modem technologies.This paper proposes a novel digital watermarking algorithm based on the numbers of the blocked middle DCT positive and negative coefficients.Embedding watermark into the middle frequency of DCT is a perfect idea and it can receive a trade-off between robustness and imperceptibility.We utilized the embedding strength to get a balance between their robustness and imperceptibility.The results show that the algorithm is robust to print and scan process.
