In the research of multi-image encryption (MIE), the image type and size are important
factors that limit the algorithm design. For this reason, the multi-image (MI) hybrid encryption …

With quaternion theory, the traditional discrete fractional Tchebyshev transform is extended
to the quaternion algebra domain for multi-image processing. A new multi-image encryption …

With the widespread adoption of smart devices and high-speed networks, investigators are
focusing on securing digital image applications, such as those on social media, in …

Recent advancement in the digital technology and internet has facilitated usage of
multimedia objects for data communication. However, interchanging information through the …

Current multiple-image encryption schemes usually require a fixed number or the same size
of images. Therefore, this paper proposes a multiple-image encryption algorithm that can …

While studying remote sensing images, it is found that the band of remote sensing images
can be used as a carrier to store different images. Therefore, this paper proposes a novel …

Chaotic encryption mostly has been proposed to protect a single image or batch images of
identical size. Typically, it splices these images into a huge one, and later performs batch …

In this paper, an encryption model for the grayscale and color images based on novel magic
square, and differential encoding technique along with chaotic map has been proposed. The …

There have been limited research studies on encryption algorithms specifically designed for
certain encryption scenarios. Aiming at different types of face images, this paper presents a …

This paper proposes an effective image encryption method to encrypt several images in one
encryption process. The proposed encryption scheme differs from the current multiple image …
