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 …

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 …

In recent years, image encryption has been broadly researched. Since a large proportion of
images on Internet are compressed, and JPEG is the most widely adopted standards for …

With the proliferation of digital images over open networks, secure and efficient encryption
schemes are imperative for safeguarding image privacy. This paper proposes a novel 5 …

People are accustomed to utilizing mobile phones to capture images and uploading them to
the cloud due to various incomparable advantages such as saving the storage space on the …

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 but to also consider …

Chaotic maps are extensively utilized in the field of image encryption to generate secret
keys. However, these maps suffer from hyper-parameters tuning issues. These parameters …

In this paper, we propose a novel image encryption scheme based on a chaotic system and
compressed sensing for multiple application scenarios. It is a dedicated scheme for JPEG …

Compression and encryption are often performed together for image sharing and/or storage.
The order in which the two operations are carried out affects the overall efficiency of digital …
