Bomeng Zhou · Journal of Quanzhou Normal University · 2009
Image encryption method based on Arnold transform and Fresnel digital holography,wavelet transform and Fresnel digital holography is proposed.The method for image encryption and decryption is realized,and the influence of the wavelength of reconstructing wave and the distance of propagation on the reconstructing image is studied.The results show that the method will get better result of encryption and decryption,image encryption method based on Fresnel digital holography will improve the sensitivity of image scrambling and has a good robustness for image cropping.
