FIELD: information technology.
SUBSTANCE: monitoring system includes a monitoring device and a verification server. The monitoring device is connected to a first receiving device for satellite positioning, which is configured to receive signals from a satellite positioning system, process the received signals to obtain observed satellite positioning parameters and calculate a position based on the observed satellite positioning parameters. The monitoring device selects an observed satellite positioning parameter based on which a position is calculated using the first receiving device for satellite positioning, and obtain from the receiving device for satellite positioning the selected observed satellite positioning parameter. The verification server verifies position consistency based on the position and based on the observed satellite positioning parameter. The verification server is further configured to generate an authentication code based on the position consistency verification result and based on positioning data.
EFFECT: reduced distortions and falsifications in a monitoring system.
