I don't mind having a layered digital ID that proves things on a wide scale of disclosure from:
1. I meet a particular attribute with no identity disclosure (like photo ID for buying alcohol)
2. I have to prove my identity for something but there's no central log
3. I have to prove my identity for something but there IS a central log
4. I not only have to prove my identity but I have to submit other personal attributes about myself (NHS number, citizenship, actual age - not just threshold, driving license number & status, etc.)
And so on...
There MUST be citizen's own control over data at a granular level and expressed against the context of the request - I may or may not choose to divulge my sexual orientation or medical history to a local authority for a parking space allocation, or my actual age to a ticket agency, when just proving I'm old enough is sufficient.
This would require an ombudsman to judge overreach of requested attributes, with meaningful sanctions.
