A compression-based text steganography method

Journal of Systems and Software, 2012
Highlights? In the present study, LZW data compression based text steganography method has been proposed. ? Capacity, one of the main problems of steganography, has been increased to 7.042%. ? By employing stego keys and Combinatorics-based coding security of the proposed method has been supported. ?

Analyses of Steganography Methods

2022
The current state and development of information systems and technologies requires information security, therefore, in this paper, the methods of steganography are considered and a new classification is given. Steganography is a method that is based on hiding or embedding additional information in digital objects, while causing some distortion of these

A robust ECG steganography method

2016 10th International Symposium on Medical Information and Communication Technology (ISMICT), 2016
ECG steganography hides patient's confidential data into their Electrocardiogram during transmission/storage of medical records, in order to ensure protection of patient privacy. Efficiency of a steganography method can be estimated using imperceptibility and robustness of hidden data which are estimated using Peak Signal to Noise Ratio and Bit Error ...

Signaling Methods for Multimedia Steganography

IEEE Transactions on Signal Processing, 2004
Conventional communication methods employ a wide variety of signaling techniques that essentially map a bit sequence to a real-valued sequence (which is a representation of a point in the signal constellation). The real-valued sequence is in turn transmitted over a communications channel.

Velody — A novel method for music steganography

2017 3rd International Conference on Frontiers of Signal Processing (ICFSP), 2017
This study describes a new method for musical steganography utilizing the MIDI format. MIDI is a standard music technology protocol that is used around the world to create music and make it available for listening. Since no publicly available method for MIDI steganography has been found (even though there are a few methods described in the literature),

A Proposed Steganography Method to Uyghur Script

2012 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery, 2012
Data confidentiality is critical for communication, which is generally achieved only by data encryption. In this paper, we proposed a hybrid data hiding approach that uses the crypto-steganography method for Uyghur script. This approach first hides the decimal values of the message letters upon the encryption with a secret key table. The decimal values

Delving into the Methods of Coverless Image Steganography

2019 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2019
Conventional cover-based image steganography methods embed secret information by modifying the original state of a cover image. This type of algorithm leaves a trace of changes on output stego image and eventually leads to successful detection by common steganalysis tools.

A compressed LSB steganography method

2017 3rd International Conference on Computational Intelligence & Communication Technology (CICT), 2017
A least significant bit (LSB) Steganography is mainly characterized by its hiding capacity and imperceptibility which is measured by Peak Signal to Noise Ratio (PSNR). There is a trade-off between these two factors. In this paper, an improved LSB Steganography which uses modulus function for data hiding method has been proposed and implemented which is
