Abstract

The degree of protection for common types of security holograms is reviewed. The possibility of hologram recording directly from the holographic film being used for protection is demonstrated. We suggest the structure of security hologram allows one to prevent such unwanted copying. We also propose a detection system which provides for fast testing of a hologram's authenticity.
