Метод персонализации фотополимерных защитных голограмм на основе записи скрытых кодированных цифровых изображений
This article deals with the problem of embedding personal data into replicated photopolymer security holograms with a maximal preservation of the hologram area during its visualization. A method of recording personalized security holograms on a photopolymer material is proposed. By this method main security hologram with a visualized image includes an additional computer-generated Fourier microhologram with individual personalized data. The synthesis algorithm and a technical implementation of the Fourier microhologram recording method are presented. The efficiency of the proposed method is confirmed by experimental studies on recording and reading of personalizing Fourier microholograms.
