Secure Data Transfer over Internet Using Image Steganography: Review

Abstract

Whether it's for work or personal well-being, keeping secrets or private information has become part of our everyday existence. Therefore, several researchers acquire an entire focus on secure transmitting secret information. Confidential information is collectively referred to as Steganography for inconspicuous digital media such as video, audio, and images. In disguising information, Steganography plays a significant role. Traditional Steganography faces a further concern of discovery as steganalysis develops. The safety of present steganographic technologies thus has to be improved. In this research, some of the techniques that have been used to hide information inside images have been reviewed. According to the hiding domain, these techniques can be divided into two main parts: The spatial Domain and Transform Domain. In this paper, three methods for each Domain have been chosen to be studied and evaluated. These are; Least Significant Bit (LSB), Pixel Value Difference (PVD), Exploiting Modification Direction (EMD), contourlet transform, Discrete Wavelet Transformation (DWT), and, Discrete Cosine Transformation (DCT). Finally, the best results that have been obtained in terms of higher PSNR, Capacity, and more robustness and security are discussed.

A Two-Level Security Layer for Medical Data

“…However, when the hidden data is discovered, steganography becomes a problem (Saleh et al, 2016). Image steganography should be robust, have good visual quality, and be secure (Okediran, 2020;Abdullah, 2021). Overall, steganography is a useful technique for keeping data private but its effectiveness depends on its ability to maintain imperceptibility and robustness while avoiding detection (Abd-El-Atty, 2023).…”

Chaos-Driven Encryption Algorithm Integrated Logistic Chua Map for Secure Medical Image Communication

“…Thus, it is essential to enhance appropriate methodologies to safeguard medical quantum images in healthcare applications. Securing digital images can be accomplished by taking advantage of image steganography [16][17][18], image watermarking [19][20][21], and image encryption [22][23][24][25]. Encryption is the optimal technique for guaranteeing the security of medical images.…”

Improved Security of a Deep Learning-Based Steganography System with Imperceptibility Preservation

“…Digital data provide a comfortable environment for editing and modifying the data that can be copied without losing data quality and content. The computer-processed digital data can be delivered from one device to another without any errors or external interference [5]. However, digital data distribution poses serious concern due to attacks or manipulation by unauthorized users, which leads to the loss of relevance, thus weakening its security aspect.…”
