"A new patent, granted to Apple, could prevent academic cheating, cinema interruptions, but also see areas of political protest activity 'ring-fenced' disabling phone and tablet cameras.
(...) It's clear that although Apple may implement the technology, it would not be Apple's decision to activate the 'feature,' such as a remote-switch -- it would be down governments, businesses and network owners to set such policies.
Those policies would be activated by GPS, and Wi-Fi or mobile base-stations, which would ring-fence ("geofence") around a building, a protest, or a sensitive area to prevent phone cameras from taking pictures or recording video.
Other features, such as email or connecting to non-authorized networks -- such as working in the office and connecting to a non-work network on a company-owned device -- could be set, for example.
This sort of 'feature' would not bode well for journalists taking photos and citizens recording acts of state violence or police brutality in areas where ordinary people are facing increasing crackdowns on civil and human rights."
