Paper Abstract

When the hologram was first introduced as a security device it was accepted as being a virtually un-counterfeitable security feature. In the decade that followed rumors grew up within the security industry that the hologram was actually far less secure than manufacturers had claimed, with some authorities stating that holograms offered no real security value whatsoever. Despite this, the use of holograms and related Diffractive Optically Variable Image Devices (DOVIDs) continues to increase both for product authentication and document security. This paper presents a number of case histories of hologram copying and simulation and attempts to differentiate the facts from the rumors on the subject of hologram counterfeiting.
