FIELD: information security.

SUBSTANCE: invention is related to methods for generating device identifiers. A method for generating a static identifier for mobile devices running iOS is claimed, comprising the following steps: installing a payment application in the operating system (OS) of the mobile device; launching the payment application and registering the user in it, while collecting parameters of the mobile device, including processor parameters, OS parameters, memory module parameters and battery parameters; translating each received parameter into an array of bits; concatenating the received array of bits of the received parameters; performing hashing of the concatenated array of bits; generating a static mobile device identifier; writing the obtained static identifier into a private memory area of the mobile device; linking the received identifier with the payment application of the specific user; transferring the received identifier to the server of the automated fraud monitoring system.

EFFECT: increasing the accuracy of identifying mobile devices by generating a static identifier.
