Abstract

In this paper, we propose off-axis hologram watermarking technology, which could raise the robustness against the personal information's copy, falsification and alteration by making it possible to insert variable type's information and making strong privacy function. This technology should use security keys, hologram's depth information and the information in proportion to the depth information, at same time to extract inserted information and could insert huge information and insert owner or provider's own information with three-dimensional hologram watermark type to digital contents. So, this could have the high security. The proposed technology is strong at several images' processing and information's damage by the usages of hologram’s redundancy and this makes it hard to recognize inserted information visually. Especially, inserting much amount's information with various type is possible with its high privacy function by inserting information to several frequency's transform plane by using Fresnel transform differently with existing watermarking. So, we will show the substantial application's possibility and robustness of Fresnel hologram watermarking technology using like that characteristics through computer's imitation simulation.
