The recent theft of nude photos of celebrities from cloud-based storage systems has sent IP lawyers scurrying to check how vulnerable their own firm’s information is to data thieves. In the US, the test being applied by corporate counsel is: assume one of your kids is trying to access a device used by you, and if your 10-year-old can access it, then it is probably not that secure.

The problem is that we want technology to be convenient – it is precisely that convenience that makes us so vulnerable.
