Creation of software based on spectral analysis for stegoanalysis of digital audio documents

The research paper examines the effectiveness of encoding secret information in audio files, its features and advantages over other types of information hiding, and the main methods of stegoanalysis. The purpose of the work is to create an algorithm for hiding information in sound files and its software content. The built-in here is to provide users with a secure information hiding environment without revealing the presence of confidential information to a stranger. The work includes information hiding methods in steganography. The characteristics and shortcomings of each method in stegoanalysis are studied. The purpose of the work is to reduce the size of the file sent through the communication channel and hide it in a sound file. That is, compatibility with the WAVE sound format is provided. In addition, the software implementation of the algorithm is developed in the Java environment. Aims to demonstrate the capabilities of stegoanalysis in Netbeans. The program is equipped with special functions that carry out stegoanalysis and allow it to be coded before stegoanalysis. All mentioned algorithms, methods, coded secret messages in the science of steganography are studied during program creation. The main goal of this research is to create a program that meets people’s needs. The research paper examines the problems of steganography and steganalysis in audio files and provides an overview of available software for hiding information in WAVE files. It has been shown that currently there is no software that meets the requirements of steganography in audio files. An additional program for WAVE audio format files for steganographic hiding using the LSB method is developed (package Stegora WaveHide). Also, an algorithm for finding hidden data is implemented.
