Abstract
In this paper we examine the use of DOVIDs (Diffractive Optically Variable Image Devices) in the verification and authentication of documents and products. The paper reviews the history of this application of DOVIDs, provides quantitative and pricing data on the market as it is now, identifying that this is the most valuable and profitable sector for the manufacturers of DOVIDs. We consider how this market may develop in the future. We conclude that DOVIDs are the market leader in branded product and document authentication and there are many sectors where healthy growth can be expected. At the same time, there is a real threat to the realization of continued growth from the activities of counterfeiters of DOVIDs. Many organizations producing these counterfeit items are highly capable and inventive; they could share the legitimate market and gain more in the long-term than they will gain in the short-term from supplying counterfeits.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
