Paper Abstract

The paper introduces the methods of making secret codes in the holograms for the purpose of anti-counterfeiting, especially the production of two kinds of visual holographic secret codes. The optical arrangements for recording are presented, and the effective results from using the visual secret codes into holographic trade marks are reported.
