Here's a prediction: twenty years from now, it will be the norm for citizens to have their own personal data stores where they store their own data, use it for their own purposes, and control who they share it with for what purposes. And our society and the economy will be better for it.

Europe's new General Data Protection Regulations (GDPR) that come into place in May 2018 has put the conversation around personal data firmly on the C-Suite agenda. And arguably, has – or will – put it firmly on individuals' agendas too. Who owns our personal data, who is it shared with and why, how it is stored and where, how (in)secure it is, are common – and important - questions that no one has concrete answers to. At least, not yet.

Historically, our data infrastructure and architecture evolved to be organisation-centric. Individuals weren't expected to collect and use their data for their own purposes. Data was something that was done by organisations for organisations' purposes such as streamlining admin costs, gaining new insights, and targeted marketing and so on.
