TL;DR: An overview of the potential, recent advances, and challenges of optical security and encryption using free space optics is presented, highlighting the need for more specialized hardware and image processing algorithms.
Journal ArticleDOI
Securing information using fractional Fourier transform in digital holography
TL;DR: In this paper, the input image to be encrypted is multiplied by a phase mask, and either its Fourier or fractional Fourier transform is obtained using interference with a wave from another random phase mask.
Journal ArticleDOI
Fully phase encryption using fractional Fourier transform
TL;DR: A fully phase encryption system, using fractional Fourier transform to encrypt and decrypt a 2-D phase image obtained from an amplitude image, and experimental results in support of the proposed idea are presented.
Journal ArticleDOI
Image encryption based on interference that uses fractional Fourier domain asymmetric keys
TL;DR: An image encryption technique based on the interference principle and phase-truncation approach in the fractional Fourier domain that offers multiple levels of security with asymmetric keys and is free from the silhouette problem.
Journal ArticleDOI
Fresnel domain nonlinear optical image encryption scheme based on Gerchberg–Saxton phase-retrieval algorithm
TL;DR: The cryptanalysis has been carried out, which proves the robustness of proposed scheme against known-plaintext, chosen-plain text, and special attacks, and a simple optical setup for decryption has been suggested.
