Image invisibility assessment for visually encrypted images

2014 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2014
A variety of perceptual encryption schemes have been studied to generate visually encrypted images for protecting visual secrecy and privacy while supporting ongoing innovation and growth in the applications of digital imagery. However, typical image quality metrics such as PSNR and SSIM are not suitable to evaluate the invisibility of visually ...

Optical image encryption based on diffractive imaging

Optics Letters, 2010
In this Letter, we propose a method for optical image encryption based on diffractive imaging. An optical multiple random phase mask encoding system is applied, and one of the phase-only masks is selected and laterally translated along a preset direction during the encryption process.

Image encryption using binary key-images

2009 IEEE International Conference on Systems, Man and Cybernetics, 2009
This paper introduces a new concept for image encryption using a binary “key-image”. The key-image is either a bit plane or an edge map generated from another image, which has the same size as the original image to be encrypted. In addition, we introduce two new lossless image encryption algorithms using this key-image technique.
