TLDR
The proposed work describes optical transformations such as Fourier transformation and Fresnel transformation based encryption and decryption of images using random phase masks (RPMs) to increase the robustness in the security applications.Abstract:
The proposed work describes optical transformations such as Fourier transformation and Fresnel transformation based
encryption and decryption of images using random phase masks (RPMs). The encrypted images have been embedded in
some secret cover files of other formats like text files, word files, audio files etc to increase the robustness in the security
applications. So, if any one wants to send confidential documents, it will be difficult for the interloper to unhide the
secret information. The whole work has been done in MATLAB®read more

Optical encryption and decryption in security-volume holograms
TL;DR: An optical security holographic memory encrypted by a random phase key and decrypted by a holographic key (a holographic optical element; HOE) is presented and demonstrated, which is the first experimental impementation to replace arandom phase mask key.
