There is big data, personal data, open data, aggregate data and anonymised data.
The single thing that every citizen and every corporate decision-maker needs to understand is that the enormous data stores that government, government agencies, corporations, trusts and individuals hold are as much a key part of national and international infrastructure as the road network.
Several companies have practical designs that offer each individual their own data account, on a cloud independent of any agency or commercial organisation.
The data would be unreadable as a whole to anyone other than the individual owner, who would allow other people access to selected parts of it, at their own discretion.
