This woman is a menace. She's one of those bully's who shout down anyone who disagrees with her. The debate should be national, open & no decisions made on how to move forward until a consensus found.
My personal idea of data protection is for me to have control of mine & no-one else, then it's my decision if I want to sell it, my decision if I want to release it & my decision if I want to keep it to my bloody self.
How about if we were all just given a memory stick with our own database on it containing as much or as little info as we wish to keep all under nationally agreed groupings. We have a choice of encryption provided by the open market for us. If you want your algorithms provided free with a packet of cornflakes as a promo thats up to you. If you want to pay for military grade you can. When you get your car tax, walk into a job centre, go to your bank or where-ever you use your key to provide what YOU wish. If someone offers you a discount or a new toaster for lifetime access to your TV viewing habits again it's up to you.
Of course not providing certain information could disqualify you from things, just like today not giving your wage slips will stop you getting a mortgage (possibly).
Some info could have a second or third layer of encryption held by a third party if needed.
If you wanted a job at GCHQ you may perhaps wish to prove you have not been surfing anarchist sites for the last 7 years. It's up to you
In the end and the whole point of this is YOU would be in control not some raving mad woman who wants to treat everyone as a child.
