DTMF token for automated out-of-band authentication
First Claim
Patent Images
1. An out-of-band authentication method comprising:
- a processor receiving a first signal indicative of an authentication token via a first communication network;
in response to receiving the signal, the processor automatically generating a second signal that is indicative of the authentication token without input through a user-interface, wherein the second signal is suitable for transmission over a second communication network, and wherein one of the first signal or the second signal is a dial-tone multi-frequency (DTMF) signal;
the processor automatically transmitting the second signal via the second communication network,wherein the first signal is received during a voice-communication session and wherein the second signal is transmitted without substantially interrupting the voice-communication session, wherein the second signal is the DTMF signal, and wherein transmitting the second signal comprises playing the DTMF signal on a voice-communication path of the voice-communication session,wherein the first signal is the DTMF signal, and wherein receiving the first signal comprises detecting the DTMF signal from an audio signal received as part of the voice-communication session.

Abstract
Methods, systems, and media for facilitating an automatic out-of-band authentication process that includes a DTMF token. The process involves receiving an authentication token via one network and automatically sending the token back through a different network. In some cases, the process may be performed without the need for any human interaction. One of the tokens is a DTMF signal that may be sent on its own or during a voice communication session over the audio path established for the session.

10. A non-transitory computer-readable medium having stored thereon instructions executable by a processor to cause a computing device to perform functions comprising:
-
receiving a first signal indicative of an authentication token via a first communication network; in response to receiving the signal, automatically generating a second signal that is indicative of the authentication token without input through a user-interface, wherein the second signal is suitable for transmission over a second communication network different from the first communication network, and wherein one of the first signal or the second signal is a dial-tone multi-frequency (DTMF) signal; and automatically transmitting the second signal via the second communication network, wherein the first signal is received during a voice-communication session and wherein the instructions are executable to cause transmission of the second signal without ending the voice-communication session, wherein the second signal is the DTMF signal, and wherein transmitting the second signal comprises playing the DTMF signal on a voice-communication path of the voice-communication session. - View Dependent Claims (11)

12. A system comprising:
-
a first communication interface configured to communicate on a first communication network; a second communication interface configured to communicate on a second communication network different than the first communication network; a processor configured to perform functions comprising; receiving a first signal indicative of an authentication token via the first communication interface; in response to receiving the signal, automatically generating a second signal that is indicative of the authentication token without input through a user-interface, wherein the second signal is suitable for transmission through the second communication interface, and wherein one of the first signal or the second signal is a dial-tone multi-frequency (DTMF) signal; and automatically transmitting the second signal via the second communication network, wherein the first signal is received during a voice-communication session and wherein the instructions are executable to cause transmission of the second signal without ending the voice-communication session, wherein the second signal is the DTMF signal, and wherein transmitting the second signal comprises playing the DTMF signal on a voice-communication path of the voice-communication session. - View Dependent Claims (13)
