Abstract: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.
