Image encryption is an efficient technique of image content protection. In this work, we
propose a useful image encryption algorithm for multiple grayscale images. The proposed …

In this paper, we proposed a novel and effective image encryption algorithm based on
Chaos and DNA encoding rules. Piecewise Linear Chaotic Map (PWLCM) and Logistic Map …

Present paper introduces a polynomial combination of one dimensional chaotic maps that is
blended in a dynamic image encryption algorithm. It is special because not only this …

We present a novel privacy-preserving scheme for deep neural networks (DNNs) that
enables us not to only apply images without visual information to DNNs for both training and …

Due to the interesting nonlinear dynamic properties of chaotic maps, recently chaos-based
encryption algorithms have gained much attention in cryptographic communities. However …

An image encryption technique using DNA (Deoxyribonucleic acid) operations and chaotic
maps has been proposed in this paper. Firstly, the input image is DNA encoded and a mask …
