SYSTEMS AND METHODS FOR LINKING DEVICES TO USER ACCOUNTS Russian patent published in 2018 - IPC G06F21/00 

FIELD: data processing.

SUBSTANCE: invention relates to the storage and transmission of data contained on a magnetic strip. Method includes: determining, by an application on a mobile communication device, the binding of an MST with the mobile communication device; sending, using the application after determining the binding of the MST, a binding information request to the MST; generating, by means of MST, an arbitrary number R_MST; sending a response to the request to the application using the MST; sending, by the application, a binding request to a server; receiving, by the application, a binding token from the server in response to the binding request, where the binding token is signed using a key corresponding to the MST and containing a personal identification number (PIN) and a number; and sending of the binding token to the MST device; verifying, by the MST, the signing the binding token with the MST key and the matching of the number the binding token with the arbitrary number R_MST in the response to the request; and setting the PIN in the MST after verifying the binding token, by which the binding of the MST the user account is carried out.

EFFECT: improved security when binding a device to a specific user account.
