| 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。 |

| This work aims to summarize the research programs of applying digital watermarking technology in anti-counterfeiting printing， to find a kind of printing anti-counterfeiting technology which is difficult to be copied, easy to be identified, of low cost and no pollution. Process of above technology applied in the field of printing anti-counterfeiting was divided into three stages which included generating and embedding watermarks, printing and scanning, extracting and detecting watermarks. Research status were discussed the in stages. Current research mainly focused on tradeoff contradiction between robustness and invisibility. Further studies could be started from influences of printing and scanning attacks on watermarks, to balance the relationship of invisibility and robustness to resist printing and scanning attacks, strengthen research on “fragility” that prevents secondary printing, descript the relationship between printing design, watermarking algorithm, printing process and parameters, establish and improve the visualization application platform for digital watermark printing anti-counterfeiting. |
