Information security with optical means, such as double random phase encoding, has been
investigated by various researchers. It has been demonstrated that optical technology …

Secure communication is of great importance in the modern world. Many methods,
techniques, and systems are used for secure communication, many of which cannot be used …

We propose an image encryption technique based on the interference principle and phase-
truncation approach in the fractional Fourier domain. The proposed scheme offers multiple …

A single channel asymmetric color image encryption scheme is proposed that uses an
amplitude-and phase-truncation approach with interference of polarized wavefronts. Instead …

Image encryption converts the images into unrecognizable forms that seems like a white
noise. Digital Chaos has also emerged as one of the important technique to design secure …

In this paper, we have proposed a new image encryption algorithm based on singular value
decomposition and Arnold transform. An original image is first transformed in fractional …

We propose a novel color image hiding scheme with three channels of cascaded Fresnel
domain phase-only filtering. The original color image is encoded into three phase masks by …

A recently proposed asymmetric cryptosystem based on coherent superposition and equal
modulus decomposition has shown to be robust against a specific attack. In this paper, we …

Optical integral imaging (II) uses a lenslet array and CCD sensor as the 3D acquisition
device, in which the multispectral information is acquired by a color filter array (CFA) …

Under the framework of computational integral imaging, a multi-image encryption scheme
based on the DNA-chaos algorithm is proposed. In this scheme, multiple images are merged …
