Abstract:
1. A method comprising: determining, by a computer-based system for capturing data packets, that a captured first data packet includes a first pattern in a coded field, wherein the first data packet includes an authorization request for a transaction; determining, by the computer-based system, that a captured second data packet includes a second pattern in the coded field that corresponds to the first pattern of the first data packet, determining, by the computer-based system, that a response time of the second data packet relative to a transmission time of the first data packet has exceeded a predetermined threshold; and transmitting, by the computer-based system, an alert message in response to the determination that the response time of the second data packet relative to the transmission time of the first data packet has exceeded the predetermined threshold, wherein the first packet and the second packet each contain a header portion and a data portion distinct from the header portion, and wherein the coded field and at least one additional coded field of the first packet are contained within the data portion of the first packet, and wherein the coded field and the at least one additional coded field of the second packet are contained within the data portion of the second packet.
