Information security consultant Nicole Miners explained the problem. “The nightmare scenario is shoulder-surfing – you might be looking at a map in a town centre, and I’m standing right behind you. At that point I know exactly where you are because there’s a giant sign telling me. It’s madness!
“If the sign showed a general circle – say, representing an acre or so – and said ‘You are somewhere near here’ it would be okay. Obviously, we’d need to make sure that the centre of the circle wasn’t the person’s location or we’re back to square one”.
