A novel double-image encryption approach has been proposed based on optical
interference and logistic map. Initially, original images are rearranged into two scrambled …

In order to increase encryption capacity and improve transmission efficiency, this paper
investigates an encryption scheme for multiple-image based on cascaded gyrator transforms …

An optical multiple-image authentication is suggested using computational ghost imaging
and total-variation minimization. Differing from encrypting multiple images into a noise-like …

A novel optical image hiding scheme based on an expansion strategy is presented under
the framework of computational ghost imaging. The image to be hidden is concealed into an …

A multiple-image encryption method based on compressed coded aperture imaging and
pixel location scrambling operation is proposed. In the encryption process, each plaintext …

We report a compressive interference-based encryption (IBE) method using sparsity
constraints. In this method, two sparse phase-only masks (POMs) are generated through a …

A novel multiple-single-channel color image cryptosystem based on unequal spectrum
decomposition (USD) and 2D sine improved 1ogistic iterative chaotic map with infinite …

A novel image multi‐encryption architecture based on hybrid keystream sequence
generated by a single hyperchaotic system and Haar discrete wavelet transform (HDWT) is …

New methods and apparatuses for information security have evolved as a result of the rapid
expansion of optical information processing. Security is one of the major issues in digital …

Data encryption is becoming increasingly relevant with the development of digital
technologies. A particularly promising direction is the development of encryption methods …
