This paper presents a new homomorphic image cryptosystem. The idea of this system is based on encrypting the reflectance component after the homomorphic transform and embedding the illumination component as a least significant bit watermark into the encrypted reflectance component.

Optical image encryption based on diffractive imaging
Optics Letters, 2010In 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.

Binary-tree encryption strategy for optical multiple-image encryption
Applied Optics, 2016In traditional optical multiple-image encryption schemes, different images typically have almost the same encryption or decryption process. Provided that an attacker manages to correctly decrypt some image, the conventional attacks upon other images are much easier to be made.

Image encryption utilizing lossy image compression
2017 International Conference on Computer, Communications and Electronics (Comptelix), 2017As the network technologies are improving, more challenges are coming forward in form of huge amount of data being transferred through the network. A large portion of such data is of multimedia type consisting of huge amount of digital images being sent and received through the network.

Image encryption using binary key-images
2009 IEEE International Conference on Systems, Man and Cybernetics, 2009This 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.

Efficient selective image encryption
Multimedia Tools and Applications, 2015Selective image encryption has a significant importance in many applications as it offers significant savings in computations, cost, and time. Many attempts are exerted for this purpose as the traditional full image encryption/decryption algorithms may be too massive. In this paper, a new technique for selective image encryption is developed.

Modified diffractive-imaging-based image encryption
Optics and Lasers in Engineering, 2019Abstract The diffractive-imaging-based image encryption (DIBE) has been breached by chosen-plaintext attack (CPA) due to the straightforward relation between the plaintext and the ciphertext. In this paper, we report a modified diffractive-imaging-based image encryption (MDIBE) scheme which inherits the merits of conventional DIBE (e. g.

Skeleton based image encryption
Proceedings of the IEEE 12th Signal Processing and Communications Applications Conference, 2004., 2004As a result of the increase in digital image transfer and the systems used for digital image transfer becoming of such importance as to matter commercially, methods of coding are applied in digital data transfer. As the digital data transfer is a simultaneous process, it requires fast working coding and decoding algorithms.
