Digital steganography has a long history, starting to be developed in the 90s until now. The
main aspects of early steganography are security, imperceptibility, and payload. Security is …

A multiple-image encryption algorithm based on single-channel scrambling, diffusion and
chaotic system is presented in this paper. The initial values of the chaotic system are …

Visually meaningful image encryption may keep the data security and appearance security
of the digital images. However, there are still security and efficiency shortcomings existing in …

A two-dimensional cross-mode hyperchaotic map based on logistic and sine maps (2D-
CLSS) is presented. The hyperchaotic map consists of a logistic map and two sine maps …

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 …

In this paper, a novel triple-image encryption and hiding algorithm is proposed by combining
a 2D chaotic system, compressive sensing (CS) and the 3D discrete cosine transform (DCT) …

Traditional image encryption algorithms transform a plain image into a noise-like image. To
lower the chances for the encrypted image being detected by the attacker during the image …

Recently, some visually secure image encryption schemes using compressive sensing (CS)
have been developed to protect images with visual security, where the images are first …

An efficient visually meaningful double color image encryption algorithm is proposed by
combining 2D compressive sensing (CS) with an embedding technique. First, two color …

In order to safely and covertly protect the digital image information during public channel
transmission and localized storage, a stable image visually secure encryption algorithm by …
