Image encryption utilizing computer generated hologram(CGH) and Duffing chaotic system

In the current study, the technology of computer generated hologram (CGH) was utilized for encoding using Duffing nonlinear chaotic system and MATLAB software. For the images produced by holograms, the results proved that it is possible for realized, recognized and get reverted back to the original image, using Duffing-chaos theory. It is observed that the images can be encrypted and disappeared of their characteristics and consequently it is possible to use method by means of image encryption. The results proved that the best way to encrypt sent images is to use dividing the phase matrix of the hologram image by the phase matrix of the attractor image, where the image features disappear completely, which means it is easy to send images with complete confidentiality.
