A server computer receives from a resource provider device transaction data, a first set of wireless communication signals available to the resource provider device, a second set of wireless communication signals available to the resource provider device, and a sound level detected by the resource provider device. The server computer retrieves from a user device a first set of wireless communication signals available to the user device, a second set of wireless communication signals available to the user device, and a sound level detected by the user device. The server computer computes a score based on the first sets of wireless communication signals, the second sets of wireless communication signals, and the detected sound levels.
