将全息数字水印技术应用于防伪印刷无需添加任何新的材料，对设备和工艺也没有特殊的要求，同时还可提高水印的不可见性，其操作性较强。综述了空间域和变换域2类全息数字水印算法的研究现状，提出了现有全息数字水印方案应用于防伪印刷中存在的问题，并展望了其研究方向，即：将现有技术和印刷实验相结合，研究不同承印物、印刷方式和原稿对该技术应用到防伪印刷中的影响，开发一套完善的、应用于印刷品的水印质量评价和鉴别体系。

Without adding any new materials, with no special requirements of equipment and processes, holographic digital watermarking could be applied in anti-counterfeiting printing and improve the watermark invisibility and operational practicality. A brief introduction of research status of holographic digital watermarking algorithm in spatial domain and transform domain is given, and the problems in applying prospect scheme in printing security are proposed. The future research direction is put forward as combining existing technology and printing with experiment, researching on the impact of applying prospect scheme by using different substrates, printing methods and techniques in anti-counterfeiting printing, developing a comprehensive system applicable to the watermark printing quality evaluation and identification.
