Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what plans her Department has made to use decentralised data storage systems in the implementation of the digital ID scheme.

We will work closely with expert stakeholders, including the Information Commissioner’s Office and the National Cyber Security Centre, to make the programme as effective and secure as possible. Our approach will involve a federated data model, to ensure privacy and security.

Overall responsibility for the scheme sits with the Cabinet Office who will be launching a public consultation in the new year, which will seek views on the design, build and delivery of the system.
