Re: My problem with Digital ID...
Exactly. Describing this as a Single Point of Failure understates the risk, since (to the bad guys, like Putin and Pooh) it is a single target.
But let's play with some numbers. Assuming a UK population of 10^8, you need pretty astonishing levels of reliability in that 1 system to avoid unacceptable risks of people suddenly finding themselves declared non-persons by all branches of officialdom simultaneously. Whereas ... if you keep several forms of ID separate at the implementation level (in the way that driving licences, passports, NHS stuff, increasingly /aren't/) then fairly achievable levels of reliability in each system make the odds of a simultaneous failure of all of them (for the same victim) almost inconceivable.
We know the systems will fail. How hard is it for a victim to recover when they do?
