It might one day be possible for cinemas and concert promoters to prevent smartphones from taking photos inside their venue, if reports about Apple’s patent #20110128384 are correct. The patent would allow phones to detect infrared signals sent out from venues containing instructions such as “stop recording video” or “do not allow photographs”. According to the patent, “a transmitter can be located in areas where capturing pictures and videos is prohibited (eg a concert or a classified facility) and the transmitters can generate infrared signals with encoded data that includes commands temporarily disabling recording functions.” Evolver
