This paper proposes a dynamic RNA-encoded color image encryption scheme based on a
chain feedback structure. Firstly, the color pure image is decomposed into red, green, and …

In the application and promotion of UAV in the future, remote sensing image information is
transmitted frequently, and its security issues will not be ignored. Aiming at the privacy …

Bit is the most basic unit of a digital image in the spatial domain, and bit-level encryption is
regarded as an important technical means for digital image privacy protection. To address …

The concept of thumbnail-preserving encryption (TPE) is proposed to strike a balance
between image privacy and visual usability. It allows users to have both without having to …

Advances in mobile communication have enabled images to be shared more conveniently,
and the consequent risk of privacy breaches has been increasingly emphasized. Previously …

The image hosting platform is becoming increasingly popular due to its user-friendly
features, but it is prone to causing privacy concerns. Only protecting privacy, in fact, can be …

Thumbnail preserving encryption (TPE) images protect privacy while still maintaining visual
usability when stored in the cloud. However, existing thumbnail preserving encryption …
