Blockchain

The recognition of the need for a user controlled identity management process is now being codified in various legislation particularly in the EU (e.g. GDPR and PSD2). This recognition is borne out by efforts such as the FIDO U2F and a body of work developed over the last 10-20 years culminating in the concept of the ‘self-sovereign’. The future is now being envisioned as a user centered experience whereby data and ownership remains with the user, and they have the ability to magically move their private information between information service providers at will.

Conversely the internet behemoths of today do not support this utopia - and it is not yet clear how users can isolate their independence and self-sovereignty from some 3rd party internet giants or government institutions. Blockchain theory and current implementations show how a world of distributed data management based on consent algorithms might pave the way to the user utopia with immutable records that can be shared securely yet completely assured and verified by the user independently of the service providers they interact with. This body of work explores the interrelated concepts of trust, completeness, availability, audit trail and anonymity.
