Event-based authentication

A system comprising:

• at least one processing circuit configured to:
• recognize an event;
• receive, from an automated teller machine (ATM), a withdrawal request of a user, wherein the withdrawal request comprises a captured feature by the ATM;
• determine that the user is associated with the recognized event using at least a geographic proximity between the event and the withdrawal request, wherein the geographic proximity is a given radius around a location of the event, and wherein the ATM is within the given radius;
• adjust authentication rules based on the determination that the user is associated with the recognized event, wherein the adjustment of the authentication rules comprises lowering a matching percentage of a matching threshold between the captured feature and a reference feature;
• and
• process the withdrawal request for the user based on the adjusted authentication rules, wherein processing the withdrawal request includes dispensing fiat currency at the ATM.

One or more non-transitory computer-readable storage media having instructions stored thereon that, when executed by at least one processing circuit, cause the at least one processing circuit to:

• recognize an event;
• receive, from an automated teller machine, a withdrawal request of a user, wherein the withdrawal request comprises a captured feature by the ATM;
• determine that the user is associated with the recognized event using at least a geographic proximity between the event and the withdrawal request, wherein the geographic proximity is a given radius around a location of the event, and wherein the ATM is within the given radius;
• adjust authentication rules based on the determination that the user is associated with the recognized event, wherein the adjustment of the authentication rules comprises lowering a matching percentage of a matching threshold between the captured feature and a reference feature;
• and
• process the withdrawal request for the user based on the adjusted authentication rules, wherein processing the withdrawal request includes dispensing fiat currency at the ATM.
