Yes you can get hair/dna/biometrics etc but you then have to compare it to a database of hundreds of BILLIONS of entry. It is clear that this is a processing issue for Honorverse computers which seem to be significantly less capable than those Abby uses in NCIS. NCIS also shows the very real problem of multiple overlapping jurisictions and databases that need to be searched in parallel only the Solarian League is hundreds of times bigger than those of just the US.
You're making a classic mistake: assuming that you have to do a full compare to every record. That is, as you say, infeasible.
What happens is that you compute a "fingerprint" that reduces the search space by quite a few orders of magnitude. That gives you some potential matches, after which you do a more rigorous compare to find the right one.
That's what services like UTube do to catch people who are uploading copyrighted material.
False positives only happen when the comparison is deliberately using less than full information, for whatever reason. (usually cost).
And remember: it's 2000 years of development later. You're not going to spoof a decent system by holding up a picture of someone else in front of the camera.
This is already how facial recognition works and it is well established that response time is exponential with database size. e.g you can get 1 second response from a database of 100k faces, 30 mins from a database of 40 million and the estimates of time for a database of 4 billiion is in the range of Months. When talking about border security in Sol we are talking about a database in the 10s of billions.
I also disagree that the computers in the Honorverse are notably more powerful than the ones we currently have and it is very clear that they do not work on quantum computing principals so I see no reason to ascribe them miraculous levels of computing power compared to current tech.
Finally the differences between differences between your legit video of Auntie Nell falling into the swimming pool and an equivalent length music video is vastly greater than the differences between 2 sets of fingerprints or facial recognition scans. the more disdinct the two objects the easier it is to create unique digital fingerprints.
Current accuracy for the FBI factial recognition database is that it gives the 50 best result matches for a suspect and only 80% of the time is the suspect actually one of those matches, even when the suspect exists in the database somewhere. This is no-where good enough for border security checks whith thousands of people an hour flowing through. Note also that other reports suggest that the FBI database can carry out hundreds of simultaneous searches at the same time. Or to put it another way screening all the passengers from a single fully loaded Airbus A 380 arriving at New York would be dangerously close to maxing out the database capability.
As I said it is good for confirming the identity of a know suspect but bad for random fishing in a massive population pool for a potential bad dude.
See https://www.theatlantic.com/technology/ ... on/397289/ for a resonably decent summary of the current state of Facial Recognition and note that they are always referring to it in the "Who is this dude" mode not "did this dude just pass the camera" mode. That mode which is what is needed for border security and remains a hollywood myth.
