FIELD: information technology.
SUBSTANCE: method and system for ensuring the protection of user transactions include a subscriber device ("SU"), an administrator of the account information ("CIM") and a service provider ("TSP"). The cyber-identifier ("CyberID"), the subscriber identifier ("SubscriberID") and the subscriber information are stored in the CIM memory. Transaction request is sent from the SU to the TSP to generate a transaction ID ("TID"), the TID is stored in the memory of the TSP and the TID is transmitted to the SU, which transmits the authentication request along with the TID and the SubscriberID to the CIM, where the received SubscriberID is authenticated and the request is transmitted for verification along with the TID received from the SU, to the TSP, which verifies the received TID and reports the CIM verification result. The CIM transmits the CyberID and the subscriber information to the TSP and transfers the transaction authorization to the SU.
EFFECT: increasing the security of online transactions by additional authority confirmation of both parties to the transaction.
