In the past, to mitigate data loss and leaks by corporations RIM would make camera-less devices. This might change with the introduction of their latest filed patent.
Their newest patent is to ‘prevent inconspicuous use of cameras.’ In other words, “the camera restriction prevents a user from taking a picture of a subject if the device has not been steadily focused on the subject in question for a predetermined period of time.”
It doesn’t specify how long the camera would have to be focused. Though, it appears it could be up to IT departments to decide. Check out the full patent details at USPTO.
