Abstract:
In accordance with some embodiments, an apparatus for privacy protection includes a housing arranged to hold a second device, a local communication device at least partially supported by the housing, and a controller, where the apparatus is associated with a radio frequency (RF) power detector. The RF power detector monitors energy emitted from one or more antennas of the second device in response to determining that the second device indicates that the second device has transitioned from a first mode of operation to a second mode of operation. The apparatus further establishes a communication channel between the apparatus and the second device, and obtains, through the communication channel, a communication status of the second device. The apparatus can then report compromise of the second device upon determining that a discrepancy between the communication status and the energy emission.
