It's straightforward to have signed data on a tamper resistant carrier that can be readily verified when arriving at a starport. We can do that today, its straightforward to put signed, digital, biometric data in a secure chip and it is readily verified, you don't need "network access" to validate the ID or read the data.If you leave a planet yes the planetary authority (and perhaps even the imperium) knows you’ve left (maybe) but when you arrive at your destination you could be anyone with any documentation - with no way to verify (modern passports are verified almost instantaneously as being real or fake).
I'm pretty sure when ships come to dock, their crew manifests are part of the arrival paperwork. Whether customs or anyone else actually goes through the crew and checks their ID, assuming they don't leave the ship, I don't know, but they probably have the right to do that. It can certainly be a crime for a captain to submit incomplete paperwork (i.e. neglecting to list a crew member).Aside from that, the starport system Traveller has pretty much allows one to evade the authorities simply by being ship's crew and never leaving the starport.
If it's officially issued, then it is what it is. The US Government can created "fake" IDs all day long. So can any other state. But it turns out that the countries tend to not favor other countries where that's common practice. "We've been hearing that your planet is giving out free IDs to pirates and criminals, so we're going to take you off our "preferred trade status" list." "Soft Power" kind of stuff.Now, after say, 8 to 10 months of being off the radar, you show up somewhere with a new passport and ID in another name that were officially issued somewhere like that.
Communication is really really slow, but travel by people is even slower. See below.My issue with ID is what a lot of this thread as argued: space is really, really large, communication is really, really slow (okay, FTL but we are talking weeks or months). and a wide variety of technological levels that may or may not support various ID protocols.
Criminal data is important because it turns out that most criminals are by their nature, criminals, vs state actors. And crime tends to follow those people wherever they go, so other authorities are keen to know when criminals are arriving in their midst.That’s an immense amount to data to constantly be transporting on xboats. Surely the 3rd Imperium has more important data (trade and taxation data) to send around rather than the warrants of some dude who allegedly offed someone.
Indeed, it is a bucket brigade, the communication is bursty, and it's travel based.The Express Network is like an "experienced crew" doing the "bucket brigade" thing on a professional basis
But the key point, addressing the "really, really slow" part above, is that the communication never stops.
At the very beginning, yea, it's a race against time. You, as a traveller, can keep up on the wave front of the messaging.
But the messaging never sleeps. A simple example is a ship arrives with electronic messaging, and may beam it to the planet while it's still 100D out. "Tetracycline IV control, this is the Wandering Fox, we've just arrived from jump, and scheduled to orbit in 7 hours. We are forwarding a mail data dump from Pegasus III." "Roger Wandering Fox, we're receiving your data." One hour later, that data in outbound on some other ship. Eventually, the people need to sleep. The messaging keeps going.
Comms are laggy, people are laggier.
