Abstract
Systems and methods are disclosed for preventing relay or replay attacks using time-stamped, localized footprint data. An access device may receive, from one or more beacon transmitters, a plurality of broadcast messages, each broadcast message, of the plurality of broadcast messages, comprising a timestamp and a unique identifier for a beacon transmitter, of the one or more beacon transmitters. The access device may store the timestamps and the unique identifiers. The access device may receive, from a user device, an access request comprising timestamps and unique identifiers corresponding to a subset of the broadcast messages received by the access device. The access device may verify that the stored timestamps and unique identifiers match the timestamps and unique identifiers received from the user device. Based on the verifying, the access device may authenticate the access request.
