We're not just talking about words here, though. You have to ask yourself:
* Who do I trust to look at the pictures in the government database?
* Who does the government trust to look at these pictures?
* Who would even be willing to look at these pictures?
These are probably disjoint sets, leading to a very empty intersection. Unfortunately, the logical impossibility of a government implementing a system that citizens should be happy with is not a barrier to it implementing some other system which it claims is good enough.
