On the subject of under 18s taking or viewing nude or "indecent" images, there was a chap interviewed on BBC News who claimed his company already had software to achieve the blocking of such images. He claimed the software worked by interacting with the phone camera and preventing inappropriate images being recorded. It also interacted with the web, to identify "incoming" inappropriate images and block them. What was not explained was:
1. how this software decided which images were inappropriate
2. how the device (ie phone, computer, tablet) was going to identify the age of the user.
3. would the age restriction apply to the device or the user, if the user, how would the device determine who was actually using it
IMHO, yet another knee jerk reaction which will produce a useless flawed law.
