I was obviously not talking about random paper-based passports but the one ID that is already standard and required for every citizen. And that one -if you decide to give it away- is tied to you, has your identity and is not easily replaced. But requiring to submit all that information on a low level internet verification process is unneccessary, when just “yes, I have that card proving I have the proper age!” is perfectly functional for that purpose.
There is no one-size-fits all solution for security. But for basic stuff like acccess to online stuff an anonymous solution based on your ID is perfectly workable. Nobody is preventing additional biometric checks for more important stuff, it’s the general things in day-to-day life we need to primarily protect from data kraken trying to profile us to make money.
We seem to talk about vastly different things or from complete different technical perspectives here, so I will take a few steps back and simplify it:
I, the government, issue your ID (with all the usual stuff making if forgery-proof). On the front is all your personal info, on the back a big marker that you are a legal adult.
If you want to buy something age-limited you just show the backside of your ID. I as the government have all your data but don’t know where you use your ID, the guy checking your ID has no data because he can trust me that I checked your age and provided a forgery-proof ID personally for you.
That’s it. That’s the whole (simplified) process. And you can reacreate exactly this concept digitally with basic cryptographic methods for online use.
So were is the problem with such a model? (Yes, I know that this is NOT what they are planning. But that’s the whole point. It is possible, the governments are just not interested because they actually don’t want to protect oyur privacy and outsourcing other methods to private companies -that do it cheaply because they want your data- is more profitable.)
