Abstract
A method of unlocking a locked device includes receiving a device identifier over a wireless communication protocol, determining if the device identifier is associated with a list of trusted devices, transmitting a request to generate an acoustic signal over the wireless communication protocol based on the determination, receiving the acoustic signal as an audio sound generated external to the locked device, estimating a distance between a source of the audio sound and the locked device, and unlocking the locked device based on the estimation.
