CPC G06Q 20/4015 (2020.05) [G06Q 20/409 (2013.01)] | 20 Claims |
1. A method for incorporating device proximity monitoring in multi-factor authentication, the method comprising:
providing a mobile device associated with a user, with an external card pocket, structured to store a user card within a Near-Field communication (NFC) field of the mobile device;
monitoring, by a user application stored on the mobile device, a connectivity status of an NFC link established between the user card, disposed in the external card pocket, and the mobile device;
generating one or more event timestamps associated with one or more detection events, wherein each detection event corresponds to a change in the connectivity status of the NFC link;
comparing, by a validation process, a most recent event timestamp from the one or more event timestamps, with a transaction timestamp associated with a transaction request message for a transaction initiated by the user card, wherein the one or more event timestamps are transmitted to the validation process by the user application;
verifying that the transaction timestamp does not exceed the most recent event timestamp by more than a predefined threshold value, wherein the most recent event timestamp corresponds to a removal of the card from the external card pocket; and
generating a two-factor strong validation response for the transaction request message based on verifying proximity of the user card to the mobile device.
