More and more privacy-sensitive images have been produced daily. Chaotic encryption
guarantees that only the targeted receiver can obtain the raw image. Many works perform …

As digital images are consistently generated and transmitted online, the unauthorized
utilization of these images is an increasing concern that has a significant impact on both …

Owing to the rapid development of cloud services and personal privacy requirements,
content-based encrypted image retrieval in the cloud has been increasing. Outsourced …

Images always contain sensitive information, eg, a clear face on a photo, which needs to be
protected. The simple way is to encrypt the whole image for hiding “everything” securely, but …

Issues such as inefficient encryption architectures, nonstandard formats of image datasets,
weak randomness of chaos‐based Pseudorandom Number Generators (PRNGs), omitted S …

This article proposed an improved 2D-logistic-adjusted-Sine map, which has better
ergodicity, pseudo-randomness, unpredictability and wider chaotic range than many existing …

A secure and reliable image encryption scheme is presented, which depends on a novel
chaotic log-map, deep convolution neural network (CNN) model, and bit reversion operation …

In this study, a novel 2D fully chaotic map (FULLMAP) derived through a multi-objective
optimization strategy with artificial bee colony (ABC) algorithm is introduced for image …

A novel optimal chaotic map (OCM) is proposed for image encryption scheme (IES). The
OCM is constructed using a multi-objective optimization strategy through artificial bee colony …

Currently, an increasing number of digital images are being generated by and for the
general public and professionals. Simultaneously, the protection of these images is crucial …
