Abstract


The article deals with the theoretical bases of creating examination tools for the authenticity of digital soundtracks and identification of digital recording equipment based on a new direction. The purpose of this article is to show some theoretical considerations underlying our developed experimental examination tools. We believe that this will be done in the form of a series of articles, which are consistently showing the theoretical and experimental background of creating practical software products and techniques for authentication of digital soundtracks and identification of digital recording equipment, embedded in the practices of expert institutions of Ukraine. It is shown that parasite processes arising up in the elements of matrices and ADCS carry steady individual character. The use of these processes is offered for the receipt of identification signs, suitable for the use in examination of integrity and authenticity of the information contained in videogrammes. These signs carry fractal character, that it can be used for their selection from noises of images and subsequent statistical treatment. The direction is grounded on the use of stray parameters of the recording equipment, fixed in intrinsic noises of phonogram arising from technological errors of manufacturing equipment.
