DETERMINING PROXIMITY OF COMPUTING DEVICES USING ULTRASONIC AUDIO SIGNATURES

摘要

In some implementations a method includes receiving a first request for a first ultrasonic audio signature from a first computing device. The method also includes transmitting first data indicative of the first ultrasonic audio signature to the first computing device. The method further includes receiving audio data from a second computing device. The method further includes determining that the audio data is indicative of the first ultrasonic audio signature. The method further includes transmitting, to one or more of the first computing device or the second computing device, a message indicating that the first computing device is in proximity to the second computing device.

1. A method comprising:
at a server including one or more processors, a non-transitory memory, and a communication interface:
receiving a first registration for a first ultrasonic audio signature from a first computing device;transmitting first data indicative of the first ultrasonic audio signature to the first computing device in response to the first registration request;receiving audio data from a second computing device;determining whether the audio data corresponds to the first ultrasonic audio signature; andtransmitting, to one or more of the first computing device or the second computing device, a message indicating that the first computing device is in proximity to the second computing device according to a determination that the audio data corresponds to the first ultrasonic audio signature.
