Paper Abstract

Embossed holograms have now been used in several areas for security purposes over the past decade. Three example applications are presented and examined in detail. The embossed hologram has many device characteristics which are common to more traditional security measures, such as paper water marks. Various methods are discussed of enhancing the security performance of embossed holograms by using them in combination with other techniques, such as, additions to the physical structure of the holographic device, the substrate on to which it is printed and the holographic image itself. It is noted that only a complete integration of all steps of manufacture can provide total security assurance.
