It's already the case. It work in a separated thread to not block the GUI...

But the registration of data computed to store in database (fingerprints)
create a lock for each SQL query, even if it's queued...

The solution is to not send a queries for a fingerprints to register, but
to group registrations, and limit database lock.

This want mean that database interface will be less unresponsive, but a
little bit in all cases.
