Abstract
In recent years, optical information security has become an important research topic. In this paper, two-layer optical information authentication method is studied by using hybrid optical encoding structures. Digital holographic setup and computer-generated hologram principle are applied respectively for the first-layer and second-layer optical information authentication. The analyses and numerical results demonstrate that the method is promising.
