Abstract
1. Способ обнаружения и исправления фальсификаций фонограмм на основе представления Хургина-Яковлева, отличающийся тем, что при формировании фонограммы используются сдвинутые друг относительно друга группы децимированных в два раза отсчетов сигнала и его первой производной, а выявление фальсификаций происходит при сравнении групп отсчетов сигнала и первой производной после обратного сдвига, а в случае, если принято решение о фальсификации, происходит оценка отсчетов децимированного сигнала по децимированным отсчетам первой производной.2. Способ по п. 1. отличающийся тем, что при формировании фонограммы используются сдвинутые друг относительно друга группы децимированных в три раза отсчетов сигнала и его первой и второй производных, а выявление фальсификаций происходит при сравнении групп отсчетов сигнала и его двух первых производных после обратного сдвига, а в случае, если принято решение о фальсификации, происходит оценка отсчетов децимированного сигнала по децимированным отсчетам первых двух производных.3. Способ по п. 1 отличающийся тем, что при формировании фонограммы используются сдвинутые друг относительно друга группы децимированных в четыре раза отсчетов сигнала и его первой, второй и третьей производных, а выявление фальсификаций происходит при сравнении групп отсчетов сигнала и его трех первых производных после обратного сдвига, а в случае, если принято решение о фальсификации, происходит оценка отсчетов децимированного сигнала по децимированным отсчетам первых трех производных.1. A method for detecting and correcting phonogram falsifications based on the Hurgin-Yakovlev representation, characterized in that when generating the phonogram, groups of twice-decimated samples of the signal and its first derivative are used relative to each other, and falsification is detected when comparing groups of signal samples and the first derivative after the reverse shift, and if a decision is made about falsification, the samples of the decimated signal are estimated from the decimated samples of the first production No.2. The method according to claim 1. characterized in that when generating the phonogram, groups of three times decimated samples of the signal and its first and second derivatives are shifted relative to each other, and fraud is detected when comparing the groups of samples of the signal and its first two derivatives after a reverse shift, and if a decision is made about falsification, the samples of the decimated signal are evaluated from the decimated samples of the first two derivatives. 3. The method according to claim 1, characterized in that during the formation of the phonogram, groups of samples of the signal and its first, second and third derivatives, shifted relative to each other, are shifted relative to each other, and fraud is detected by comparing the groups of samples of the signal and its first three derivatives after the reverse shift and if a decision is made about falsification, the samples of the decimated signal are evaluated from the decimated samples of the first three derivatives.
