Abstract

Holograms as security devices are very important and used in a wide range of areas today. Therefore, hologram manufactures are continually developing new features that are more difficult to counterfeit. In this paper, the types and features of security holograms are reviewed. We also report on the latest hologram product, "DNP LED Authentication Hologram," which enables authentication by using an LED point-light source.
