Способ относится к электронной акустике и может быть использован при создании систем охраны носителей информации и кодовых датчиков. Изобретение обеспечивает эффективную электроакустическую защиту с учетом индивидуальных признаков объекта. Для этого регистрируют параметры электроакустической системы на разных частотах в одной или нескольких точках в виде случайных чисел, а о несанкционированном доступе к защищаемой информации судят по изменению совокупности случайных чисел.The method relates to electronic acoustics and can be used to create systems for the protection of storage media and code sensors. The invention provides effective electroacoustic protection with regard to individual features of the object. To do this, register the parameters of the electroacoustic system at different frequencies at one or several points as random numbers, and unauthorized access to the protected information is judged by the change in the aggregate of random numbers.
