Researchers have designed a new image encryption scheme that combines a chaotic polycyclic shift operator with a chaotic ...
Researchers have combined DNA-based key generation with the chaotic Arnold Cat Map to create a hybrid image encryption scheme ...
We introduce an information-hiding camera integrated with an electronic decoder that is jointly optimized through deep learning. This system uses a diffractive optical processor, which transforms and ...
Introduction: Internet of things (IoT) compose of million of devices connected together over the internet. IoT plays a vital role now a days and especially in future, the most of the monitoring and ...
Abstract: This article deals with digital representation of images as well as presents design and implementation of message security of data represented in images by using the Quick Response (QR) code ...
Structural colors are promising candidates for their antifading and eco-friendly characteristics. However, high cost and complicated processing inevitably hinder their development. Here, we propose a ...
Bl-IEA is a research-based implementation of a bit-level fingerprint image encryption algorithm combining the Modified Pseudo Hadamard Transform (MPHT) and a Chaotic Skew Tent Map. It achieves strong ...
1.1使用matlab自带的imread函数读取图像，同时使用imresize函数调整图像大小为256*256 Arnold 变换，又称为 cat 映射。该变换的本质操作是拉伸和折叠，通过这两种操作可以改变图像内各像素点的空间 ...
