Exchange of patient record over network required a technique to guarantee security and
privacy for tele-health services. This paper presents an improved watermarking technique …

With the rapid growth of data transmission technology, image encryption is becoming a
widely discussed topic in the field of information security. In this paper, we introduce a novel …

This paper presents an image encryption algorithm based on the compressive sensing and
a hyperchaotic map, which includes the permutation, compression and diffusion processes …

To increase the robustness against common attacks, a novel image encryption algorithm is
proposed based on the phase-truncated short-time fractional Fourier transform (PTSTFrFT) …

The fractional-order chaotic systems have characteristics of the all chaotic systems,
however, the improper fractional-order chaotic systems have more complexity random …

Privacy preservation has become a prerequisite for modern applications in the cloud, social
media, Internet of things (IoT), and E-healthcare systems. In general, health and medical …

The secure key generation is the predominant requirement of an image encryption. Chaotic
maps are often considered by the researchers for secure key generation. However, chaotic …

Smart cameras and image sensors are widely used in industrial processes, from the
designing to the quality checking of the final product. Images generated by these sensors …

Due to the unpredictability and complexity properties, chaotic maps are widely applied in
security, communication, and system control. Existing one-dimensional (1D) chaotic maps …

This paper proposes a new chaotic image encryption, which is based on the coupled map
lattices (CML system) and DNA diffusion sequences, and it's also a new one-time pad …
