Abstract
Disclosed are various embodiments for determining if a requesting client is within a predetermined distance of a location of a trusted client. In one embodiment, a trusted signal having a plurality of trusted signal metrics may be established by the trusted client as being associated with a specified location. The trusted signal may then be rendered to the requesting client to be recorded as a contested signal. In one embodiment, an authentication service may then determine if the contested signal is of an adequate signal quality according a predetermined quality threshold. Assuming the contested signal is of an adequate quality, the authentication service then determines that the requesting client is within a common acoustic environment as the trusted client if the contested signal corresponds to the trusted signal by comparing a plurality of contested signal metrics with a plurality of trusted signal metrics.
