【摘要】：目的綜述將數(shù)字水印技術(shù)應(yīng)用于印刷防偽領(lǐng)域,開發(fā)具備"難仿制、易識別、低成本、無公害"特點的印刷品防偽技術(shù)的研究進展。方法將該技術(shù)在印刷防偽領(lǐng)域應(yīng)用流程劃分為包括水印生成與嵌入、印刷-采集過程、水印提取與檢測3個階段并分階段探討其研究現(xiàn)狀。結(jié)論現(xiàn)階段研究主要著力權(quán)衡魯棒性和不可感知性之間的矛盾,進一步研究可從印刷-采集圖像攻擊對水印的影響著手,從而權(quán)衡水印不可感知性與抗印刷-采集攻擊魯棒性之間的關(guān)系,加強對水印"防二次印刷"脆弱性的研究,描述印刷原稿、水印算法和印刷工藝參數(shù)之間的關(guān)系,建立并完善數(shù)字水印印刷防偽可視化應(yīng)用平臺。
[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.
