【摘要】：目的综述将数字水印技术应用于印刷防伪领域,开发具备"难仿制、易识别、低成本、无公害"特点的印刷品防伪技术的研究进展。方法将该技术在印刷防伪领域应用流程划分为包括水印生成与嵌入、印刷-采集过程、水印提取与检测3个阶段并分阶段探讨其研究现状。结论现阶段研究主要着力权衡鲁棒性和不可感知性之间的矛盾,进一步研究可从印刷-采集图像攻击对水印的影响着手,从而权衡水印不可感知性与抗印刷-采集攻击鲁棒性之间的关系,加强对水印"防二次印刷"脆弱性的研究,描述印刷原稿、水印算法和印刷工艺参数之间的关系,建立并完善数字水印印刷防伪可视化应用平台。
[Abstract]:Objective to summarize the research progress of digital watermarking technology in the field of printing anti-counterfeiting, which has the characteristics of "hard to copy, easy to identify, low cost, no pollution". Methods the application process of this technique in the field of printing anti-counterfeiting is divided into three stages: watermark generation and embedding, print-acquisition process, watermark extraction and detection, and its research status is discussed in stages. Conclusion at the present stage, the research focuses on balancing the contradiction between robustness and imperceptibility, and further studies the effect of print-acquisition image attack on watermark. In order to balance the relationship between the inperceptibility of watermark and the robustness of anti-print-collection attack, the research on the vulnerability of watermark "anti-secondary printing" is strengthened, and the relationship among printing originals, watermarking algorithms and printing process parameters is described. Establish and perfect digital watermark printing anti-counterfeiting visual application platform.
