Abstract:
The article considers one of the most technologically advanced groups of document and banknote security features - diffractive optically variable image devices (DOVID). Over the last decades, they have been developing the most actively both technologically and in terms of increasing the attractiveness of secured printing products. According to research, DOVID (holograms) along with watermarks are the most easy-to-remember and recognizable security features for consumers. The popularity of DOVID lies in their durability and universality. Manufacturers strive to make them verifiable both at the entry-level (due to the variety of optically variable effects) and at the expert level - by document forensic experts, using special equipment which allows to determine the optical variability of the security feature in general, as well as the physical parameters of the diffraction grating (its period and orientation) in particular. The article reviews the process of development of these security features, notes the main manufacturers and their products, used in the manufacture of secured printing products, briefly outlines the general principle of their functionality, gives illustrations of some of them, and highlights the main reasons for the increased popularity of DOVID. In addition, there are presented devices that help to verify the authenticity of security features.
