This work develops a novel lossless multiple color image encryption based on multi-layer
permutation-substitution operations. Initially, sixteen RGB images are converted into a single …

We introduce a novel image encryption and decryption algorithm for multiple images
incorporating multiple parameter fractional discrete cosine transform (MPFrDCT), 3D Arnold …

A new algorithm for biometric templates using a 6D-chaotic system, and 2D fractional
discrete cosine transform (FrDCT) is proposed in this paper. In this technique, the biometric …

This research paper proposes a novel encryption and decryption scheme for biometric
templates using two dimensional discrete wavelet transform (2D-DWT) and three …

Secure and efficient transmission of images from a sender to a receiver through the public
channel has become a prime agenda. An encryption algorithm to secure three color images …

This paper proposes a new technique for image data security using the concepts from graph
theory. The proposed technique considers the pixels of the digital image as vertices of a …

Now a days, The security of digital data is an important task. In this paper, we propose a
novel method of digital color-image encryption and decryption based on elliptic curve …

The chaotic map including 2D-Henon and Tent maps, have been widely used in modern
cryptography, due to its high level of security and low cost of computation, compared to …

A novel scheme for security of triple color images using a 6D hyperchaotic system and equal
modulus decomposition (EMD) in a two-dimensional fractional discrete cosine transform …

This paper presents a solution for the security of few-detail images in real-time applications
over open or unsecure networks depending on diffusion and confusion operations. The …
