Abstract
A content management method uses a portable multifunction device 202 to detect human-inaudible acoustic signals 210, when that signal is heard from the surrounding environment by a device microphone 113 or is output by the device's audio circuitry 100. The device 202 extracts a code from the inaudible signal and supplies the code via wired or wireless communication 232, along with additional optional data regarding the device and/or its user, to a content management system 200. Upon receipt of the code, indicating the received inaudible signal 210 from the portable multifunction device 202, the content management system 200 may provide particular content or a pointer to that content to the portable multifunction device 202, the content being selected based on the particular inaudible signal received. Additional threshold triggers 502 may be delivered to require additional actions to unlock the content.
