Journal ArticleDOI
Image fusion using wavelet transform and its application to asymmetric cryptosystem and hiding
Isha Mehra,Naveen K. Nishchal +1 more
TL;DR: Computer simulation results support the idea of the proposed fused color image encryption scheme, which provides enlarged key space and hence enhanced security in the asymmetric encryption scheme.
Journal ArticleDOI
Optical image encryption using equal modulus decomposition and multiple diffractive imaging
TL;DR: The simulation results and the security analysis demonstrate that EMD based on multiple intensity pattern recording is an effective optical asymmetric cryptosystem suitable for securing data and images.
Journal ArticleDOI
Optical asymmetric image encryption using gyrator wavelet transform
Isha Mehra,Naveen K. Nishchal +1 more
TL;DR: The computer simulation results demonstrate the abilities of the gyrator wavelet transform as an effective tool, which can be used in various optical information processing applications, including image encryption, and image compression.
Journal ArticleDOI
Collision in Fresnel domain asymmetric cryptosystem using phase truncation and authentication verification
TL;DR: Collision is a phenomenon in which two distinct inputs produce an identical output, so if an attacker finds the encryption keys in such a way that when it is applied to an encrypted image, it produces an arbitrary image instead of original one.
Journal ArticleDOI
Optical asymmetric watermarking using modified wavelet fusion and diffractive imaging
Isha Mehra,Naveen K. Nishchal +1 more
TL;DR: This article has transferred the support constraints which are generated by axial translation of CCD camera using amplitude-, and phase- truncation approach, into different meaningful images, by developing modified fusion technique in wavelet transform domain.
