FIELD: physics.
SUBSTANCE: invention relates to collection of user device identifiers. Method includes the following steps: receiving, to a user device identifier collection device from at least one user communication device, a test request for searching for wireless access points, containing a random MAC address of this device and a set of recent Wi-Fi networks, to which the user communication device is connected; generating a Wi-Fi network identifier (SSID) by a user device identifier collection device based on a set of Wi-Fi networks obtained in a test request at a previous step; sending a test response from the device for collecting user device identifiers, containing information that this device is trusted for the user and has the ability to connect to it; receiving from the user device an authorization request based on the generated Wi-Fi network identifier (SSID) to the user device identifier collection device containing the real MAC address of the device; cancelling the authorization request received from the user device by the user device identifier collection device; a test request for searching for wireless access points is obtained on a device for collecting user device identifiers, which contains the real MAC address of the device.
EFFECT: high accuracy and reliability of obtaining the real MAC address of the device, which is indicated in the firmware of the device, by bypassing the randomization mode.
