Nowadays, security in data transfer is of special importance. Images are of the most
attractive kinds of data in the encryption domain. Color images are more attractive than the …

With the development and popularization of computer network technology, the copyright
protection of stereo images is a serious problem to be solved. Based on ternary number …

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 rapid development of multimedia technology, the image scrambling for information
hiding and digital watermarking is crucial. But, in quantum image processing field, the study …

For joint image compression and encryption schemes, the encryption power and
compression efficiency are commonly two contradictory things. In this paper, we propose a …

In the last decade, with a rapid increase in multimedia productions, image encryption has
become a significant part of information security. The inherent image features make image …

This paper presents a robust color image watermarking algorithm based on fuzzy least
squares support vector machine (FLS-SVM) and Bessel K form (BKF) distribution, which is a …

In this paper, we propose an image compression-encryption method based on two-
dimensional (2D) sparse representation and chaotic system. In the first step of this method …

With the advent of multimedia technology and rapid data transmission ability of networks,
images have become a vital source of extracting information. So its security becomes a …

The paper presents an approach to encrypt the color images using bit-level permutation and
alternate logistic map. The proposed method initially segregates the color image into red …
