Using an audio channel for authenticating a device

摘要

Systems, methods, and other embodiments associated with using an audio link for authentication services are described. According to one embodiment, an apparatus includes The apparatus includes a processor configured to monitor an audio channel for an authentication signal. The authentication signal is an analog signal provided from a host device over the audio channel to the processor when authenticating the apparatus. The apparatus includes an authentication module configured to generate an authentication response after the authentication signal is detected by the processor. The processor is configured to provide the authentication response as an audio signal on the audio channel to a speaker.

1. An apparatus, comprising:
a processor configured to monitor an audio channel for an authentication signal from a host device, wherein the authentication signal is an analog signal received from the host device over the audio channel to the processor when authenticating the apparatus; and an authentication module configured to generate an authentication response after the authentication signal is detected by the processor, wherein the processor is configured to provide the authentication response as an audio signal on the audio channel to control a speaker to transmit the authentication response as sound waves to the host device wherein the processor is configured to, upon detecting the authentication signal on the audio channel, divert the authentication signal from being provided to the speaker via the audio channel to providing the authentication signal to the authentication module, wherein the processor is configured to divert the authentication signal to initiate an authentication process between the apparatus and the host device and to prevent the authentication signal from being provided to the speaker.
