Maybe you're looking at hiding information the wrong way mate. Perhaps the trick is to let them have the majority of the information but hide its context.
Simple example. 8746352237 I am sure is someone's bank account number which I've just shown to the world, I could probably give you more details, but without one particular key detail. Its useless to you.
We need to pick and choose carefully what we protect and what doesn't really matter. I truly think this is the way forward in regards personal information security.
