Electronic transaction authentication based on sound proximity

摘要

A computer program product comprises computer usable program code for receiving data describing a proposed electronic transaction between first and second communications devices. Additional computer usable program code is provided for generating a first audio signal by sound detected by a first microphone of the first communications device, and for generating a second audio signal by sound detected by a second microphone that is part of the second communications device. Still further computer usable program code provides for authenticating that the first communications device and the second communications device are in the same proximity in response to determining that the first and second audio signals were produced by the same sound event, and for completing the proposed electronic transaction between the first and second communications device in response to authenticating that the first and second communications devices are in close proximity.

主权项

1. A computer program product including computer usable program code embodied on a non-transitory computer readable storage medium, the computer program product comprising:
computer usable program code for receiving data describing a proposed electronic transaction between a first mobile communications device and a second communications device; computer usable program code for generating a first audio signal by sound detected by a first microphone that is part of the first mobile communications device; computer usable program code for generating a second audio signal by sound detected by a second microphone that is part of the second communications device; computer usable program code for authenticating that the first mobile communications device and the second communications device are in the same proximity in response to determining that the first audio signal and the second audio signal were produced by the same sound event; computer usable program code for completing the proposed electronic transaction between the first mobile communications device and the second communications device in response to authenticating that the first mobile communications device and the second communications device are in close proximity; and computer usable program code for causing at least one of the first microphone and the second microphone to detect a first sound and a second sound so that at least one of the first mobile communications device and the second communications device can detect changes in sound pressure at the nodes or anti-nodes of the first and second sounds, wherein the first mobile communications device has a first speaker that generates the first sound and the second communications device has a second speaker that generates the second sound, and wherein the first and second sounds have different frequencies.
