thesis on steganography

Steganography is the art and science of hidden (or covered) communication. In digital steganography, the bits of images, videos, audio and text files are tweaked to represent the information to hide. This paper covers the current methods for hiding ...

Adaptive spatial image steganography and steganalysis using perceptual modelling and machine learning. ... and generating stego images from the knowledge of the CNNs.Several contributions are made for both image steganography and steganalysis in this thesis. Firstly, inspired by the Ranking Priority Profile (RPP), a new cost function for ...

Our proposed steganography system is based on the use of generative adversarial networks. The training of this steganographic system is conducted using three neural networks that compete against ...

Image Steganography: A Review of the Recent Advances

Image steganography can be broadly classified into spatial domain, transform domain, spread spectrum and model based steganography as depicted in Fig. 4.In spatial domain, secret message is embedded in pixel value directly whereas transform domain methods achieve embedding by first transforming the image from spatial to frequency domain using any one of the transforms such as discrete cosine ...

Comprehensive survey of image steganography

Image Steganography works in two different domains; Spatial Domain and Transform Domain where each of them has its techniques and methods. In this thesis two methods will be studied, one from each domain. Least Significant Bit (LSB) is an image steganography technique that will be studied in spatial domain, and Discrete Wavelet Transformation ...

Thesis submitted to the Indian Institute of Technology Guwahati for the award of the degree of Doctor of Philosophy in Computer Science and Engineering ... Indian Institute of Technology Guwahati Feb, 2021. Abstract Steganography is an art of covert communication where a message is hidden in some natural-looking objects such that no one can ...

Image steganography involves the process of concealing sensitive information in the cover image to achieve secret communication. The counterpart of steganography is image steganalysis, which is used to detect any hidden information that is being communicated among different entities. The image steganalysis has gained much attention in the recent past from the information law enforcement as ...

The review includes a classification of the different steganography methods, including spatial domain, frequency domain, and transform domain techniques. Each method studied providing ability to go through any image processing operations, security, robustness, and ability to detect the hidden information. To assess the benefits and drawbacks of ...

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 ...

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 ...

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 ...

Abstract. Steganography is the science that involves encrypting data in a suitable multimedia carrier, such as image, audio, and video files. The main purpose of image steganography is to hide the data in images. This means that it encrypts the text in the form of an icon. Steganography is done when there is communication takes place between ...

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.

Abstract and Figures. Steganography is a technique of hiding information in digital media in such a way that no one apart from the intended recipient knows the existence of the information ...

Steganography and steganalysis is a relatively new-fangled scientific discipline in security systems and digital forensics, respectively, but one that has matured greatly over the past two decades. In any specialism of human endeavour, it is imperative to periodically pause and review the state of the discipline for what has been achieved till date. This article scrutinizes where the ...

3 Department of Biomedical Engineering, Amirkabir University of Technology, Tehran, Iran. *[email protected]. Abstract: Recently, merging signal processing techniques with information security services has found a lot of attention. Steganography and steganalysis are among those trends.

This technique is the most v aluable as steganography becomes a part of the image. and it's based on embedding the data by image marking. As the secret data will. be hidden in the part of the ...

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

And the processing of an image and the efforts of statistical analysis needed for breaking steganography algorithms are known as "steganalysis" or "attacks.". The classical model for modern steganography was proposed by Simmons in 1984 as "the prisoners' problem" (Simmons, 1984). An example is illustrated in Fig. 1.1 ...
