Re: A medical researcher's perspective...
medical research has a better history of securely handling data than the rest of the public sector, as the sharing of information is based on the concept of informed consent, something that is hard to get, and even harder to regain when trust is lost.
Very true but informed consent is notably absent in what people are being opted into. Opting out is made as difficult as possible and it simply isn't being explained clearly.
You have done a pretty good job presenting a case for; so why could the government not do an equally good job? The suspicion must be that they deliberately chose not to, do not want to, and that suggests there is something we are not being told, something they don't want us to know, and is a good enough reason alone to be highly suspicious.
Private companies are not routinely going to be given access to this data... the 'Tories' are not planning on selling of the un-anonymised data to their chums in the insurance industry.
I. and I suspect others, would like to see some guarantee of that. Call us untrusting, paranoid, whatever, and that is okay, we are entitled to be. It is for the government to convince us that what you say will be the case.
