Mathematical and software detection and localization of falsification of digital audio signal saved in the format with loss of information // Diploma work of educational level "Master" // Televyak Pavlo Anatolyevich // Ternopil National Technical University named after Ivan Pulyuy of Information Systems and Software Engineering, Department of Computer Science, Sam-61 group // Ternopil, 2019 // C. – 124, fig. - 25, tab. - 7, add. - 2, bibliography. sources –57.
Research methods are based on the principles of system analysis, the apparatus of computational mathematics, methods of logical design and procedural algorithmization, techniques of object-oriented and logical programming.
The purpose of the study is to develop mathematical and software for the detection and localization of falsification of digital audio signal stored in a lossy format.
The algorithm for detection and localization of falsification of digital audio signal saved in the format with loss of information was further developed.
For the first time, it was proposed to use the predetermined value of 40 as a threshold for separating a portion of digital audio containing falsification from the original parts.
The object of the study is the process of detecting and localizing digital audio tampering.
The subject of the research are methods and means of solving the problem of the process of detection of digital audio signal tampering
