In the era of information, secret communication is one of the most important issues in today's
communication systems. The development of digital communication with data secrecy …

The combination of pixel value differencing (PVD) and least significant bit (LSB) substitution
gives higher capacity and lesser distortion. However, there are three issues to be taken into …

Most of the steganography techniques, based on pixel value difference, use the difference
between the pixel values to hide the information. In this paper, an algorithm is proposed …

Steganography is an art of disguising the fact that communication is going on by concealing
information in other information. In general, the communication carrier can be files in many …

This paper proposes an image steganography technique based on the principle of pixel
overlapping to improve the embedding capacity (EC) and peak signal-to-noise ratio (PSNR) …

Presently, the design and development of an effective image steganography system are
facing several challenges including the low capacity, poor robustness and imperceptibility …

This study presents a new adaptive data-hiding method based on least-significant-bit (LSB)
substitution and pixel-value differencing (PVD) for grey-scale images. The proposed method …

As we all know security is needed when we want to send data over any medium so this
requires a secure medium to send data. That's why steganography comes in mind whose …

Rapid advances in digital technology have facilitated us to transfer a huge amount of
electronic files over the internet. But in the presence of malicious attackers, the security, as …

Picture quality and statistical undetectability are two key issues related to steganography
techniques. In this paper, we propose a closed-loop computing framework that iteratively …
