Is there any legal obligation to store sensitive ID information in its
original form? Storing a hashed version only would be sufficient to prove
the details had been collected and verify any future ID verification
requirements without actually retaining the sensitive data.

Separately, should the government provide an opt in two factor ID
verification service for critical services such as telco, utilities,
banking, etc? There are privacy concerns, however if implemented correctly
they wouldn't be collecting any further information than what they legally
have access to now.
