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 …

The amount of data exchanged via the Internet is increasing nowadays. Hence, data security
is termed as a serious issue while communication of data is processed over the Internet …

Peak signal to noise ratio (PSNR) and structural index similarity (SSIM) are two measuring
tools that are widely used in image quality assessment. Especially in the steganography …

Recently, extensive research has revealed the enormous potential of deep learning in the
application of image steganography. However, some defects still exist in previous studies on …

Images are very important forms of data that are widely used nowadays. Every day, millions
of grey and color images are transferred via the web. Protecting these images from …

Recently, generative steganography that transforms secret information to a generated image
has been a promising technique to resist steganalysis detection. However, due to the …

A new meaningful image encryption algorithm based on compressive sensing (CS) and
integer wavelet transformation (IWT) is proposed in this study. First of all, the initial values of …

This paper introduces an image encryption algorithm shorted as CITSPD, manipulated by
circle index table scrambling and partition diffusion. Firstly, the circle index table is obtained …

With the rapid development of blockchain technology, the security of non-fungible tokens
(NFT) in the transaction process has attracted much attention. In the transaction process, the …

Chaos-based encryption schemes have attracted many researchers around the world in the
digital image security domain. Digital images can be secured using existing chaotic maps …
