Steganography is a technique for sending secret messages across ordinary cover carriers in such a way that the presence of the messages is unnoticed. There are various steganographic techniques ...
Image Steganography: A Review of the Recent Advances
Image Steganography is the process of hiding information which can be text, image or video inside a cover image. The secret information is hidden in a way that it not visible to the human eyes. Deep learning technology, which has emerged as a powerful tool in various applications including image steganography, has received increased attention recently. The main goal of this paper is to explore ...
A Systematic Review of Computational Image Steganography Approaches
In image steganography, the statistical model of an image is crucial for hiding information in less detectable pixels and attaining better protection. This paper aims to present a systematic review of image steganography approaches. Articles are selected from reputable databases such as IEEE Explore, Web of Science (WOS), ACM, and Willey. ...
PDF Studies on Image Steganography
Khamis, Hamdi: Studies on Image Steganography Master's thesis, 51 p. Supervisors: Pekka Toivanen and Antti Väänänen March 2021 Abstract: Images play a big role in our digital environment and keeping them safe during the data transfer process can be a difficult task. While there are many methods to safely transfer
Comprehensive survey of image steganography: Techniques, Evaluations
Palette based steganography: Palette based steganography [107] used palette-based images as the cover media. Image formats such as PNG, GIF and TIFF are suitable for this approach. A secret key is used to generate pseudo random numbers and the selected secret data bit gets engraved on a single cover pixel. Instead of original colour, the colour ...
Steganalysis and steganography by deep learning
Image steganography is the art of secret communication in order to exchange a secret message. In the other hand, image steganalysis attempts to detect the presence of a hidden message by searching ...
Exploring the Effectiveness of Steganography Techniques: A Comparative
This research paper explores the use of image steganography for data communication. It provides an overview of data communication and steganography and focuses on the specific area of image steganography. It surveys various algorithms, including traditional and recent techniques, such as least significant bit insertion and neural network-based approaches. The importance of security ...
[PDF] An overview of image steganography
This paper intends to give an overview of image steganography, its uses and techniques, and attempts to identify the requirements of a good steganographic algorithm and briefly reflects on which Steganographic techniques are more suitable for which applications. : Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. Many ...
Steganography
This book provides a selection of chapters on the subject of steganography. Steganography is the practice of undetectably altering a digital work to embed a message. The undetectability of the message in the altered work is an essential property of steganography, whereas the required alterations in the work may be perceived as long as the hidden information is undetectable and therefore also ...
Robust steganography in practical communication: a comparative study
Steganography, one type of information hiding, is a science and art of transmitting secret bits in a covert channel [1, 2].Different from watermarking technique for protecting copyrights [], steganography conceals the existence of covert communication by embedding message into media as cover.Conventional media, including text [], image [], audio [], video [], are widely used for steganography ...
PDF Toward a theory of Steganography
My thesis initiates the study of steganography from a cryptographic point of view. We give a precise model of a communication channel and a rigorous de nition of steganographic security, and prove that relative to a channel oracle, secure steganography exists if and only if one-way functions exist. We give tightly matching upper and lower ...
A review on image steganographic techniques based on optimization
This review paper explores the use of optimization techniques in steganography, the art of hiding secret information within other data. Steganography is a field that has gained significant attention in recent years due to the increasing need for secure communication and data protection. Optimization techniques have been shown to be effective in improving the performance of steganography ...
An efficient steganographic technique for hiding data
Steganography is the technique for hiding data and aims to hide data in such a way that any eavesdropper cannot observe any changes in the original media. The least significant bit (LSB) is one of the most public techniques in steganography. The classical technique is LSB substitution. The main idea of this technique is to directly alter some LSB of the cover image with the secret data. The ...
A Review on Text Steganography Techniques
Steganography is an appropriate method, in which the user is able to conceal a message inside another message (cover media). Most of the research on steganography utilizes cover media, such as ...
StegaDDPM: Generative Image Steganography based on Denoising Diffusion
Image steganography is the technology of concealing secret messages within an image. Recently, generative image steganography has been developed, which conceals secret messages during image generation. However, existing generative image steganography schemes are often criticized for their poor steganographic capacity and extraction accuracy.

PDF Security Enhancement of Image Steganography Using
Steganography is a security method that hides secret data inside cover media where the very existence of the embedded secret data is not perceptible. The cover object can be image, audio or video; the most commonly used is an image file. This thesis presents a model for protecting the security and integrity of secret data
