In recent years, there has been significant development in multimedia technologies.
Transmission of multimedia data such as audio, video and images over the Internet is now …

Aiming at the security and efficiency of image transmission, a fast image encryption
algorithm based on an improved 6-D chaotic system is proposed. Firstly, we design a hyper …

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 …

During last few years, transmission of digital multimedia data (images, audios and videos)
over Internet, wireless cell phones, television broadcasting etc., has been significantly …

基于有限整数域上的三维仿射变换和复合混沌, 提出了一种新的数字图像加密算法,
先置乱图像中像素的位置并根据像素坐标混合像素值, 然后依次进行非线性的扩散, 代换 …

In this paper, a novel image encryption scheme based on DNA coding and multi-chaotic
maps is proposed. By combining XOR, XNOR, bit shift with some biologic operations, the …

Based on the fractional discrete cosine transform with multiple generating sequences
(MGSFrDCT) and the dependent scrambling and diffusion (DSD), an image encryption …

In recent years, a significant improvement in multimedia technologies has been observed
and therefore, transmission of these data over the network is very common. The network …

In today's digital world, security is a preeminent element in the transmission of digital
images. In this paper, image encryption algorithm is proposed using fractional transform and …

World has become a global village after introduction of social media and social networks.
However, it extensively increased the demand for network resources, particularly multimedia …
