Method of Personalization of Photopolymer Security Holograms Based on Recording Hidden Encoded Digital Images

摘要

The scope of problems of embedding personal data when copying holograms on a photopolymer substrate with the maximum preservation of the region of a hologram during its visualization is considered. A method for recording the personalized security holograms on a photopolymer carrier, which contain a supplementary computer-synthesized Fourier microhologram with individual data in addition to the main hologram with a visual image, is proposed. The synthesis algorithm is given and the technical implementation of the Fourier microhologram recording method is presented. Experimental research performed on recording and reading of personalized Fourier microholograms has confirmed the efficiency of the proposed method.
