FIELD: computer technology.
SUBSTANCE: invention relates to computer technology. The result is achieved by connecting the computer hardware to the radio masking device, launching it, as well as launching the software under the administrator account, entering the initial data for calculating the signal-to-noise ratio, launching the radio masking device, computer hardware and software under the user account, analyzing the state of activation and operability of the radio masking device, open the electronic document file, calculate the threshold value of the signal-to-noise ratio of the image, the informative signal/noise ratio is calculated and the obtained values of the indicators are compared according to the criterion of the effectiveness of protecting text documents, according to which the radio masking device is not active, and if it does not match, the deviation value is calculated, a command is generated about the required radiation power level of the noise signal generator of the radio masking device and the output power of the noise signal generator is changed.
EFFECT: increasing the security of informatization facilities from the effects of technical means of industrial espionage.
