Using sound to verify location
Abstract:
Method, apparatus, and computer program product are provided for verifying location using sound. In some embodiments, location data representing an unverified location of a first electronic device are received. Audio data generated based on sound detected by a sensor of the first electronic device during a predetermined time are received, as well as audio data generated based on trusted sound detected by a sensor of a second electronic device during the predetermined time, wherein the second electronic device is located near the unverified location of the first electronic device, and wherein the trusted sound includes one or more frequencies inaudible to humans (e.g., infrasonic and/or ultrasonic sound). The audio data generated by the first and second electronic devices are analyzed and a similarity score representing a similarity between the respective audio data is generated. The unverified location of the first electronic device may be verified based on the similarity score.
