From my understanding this age verification app seems to be based on the age verification blueprint they have been working on for a while now, which is supposed to be part of the European "digital wallet"

https://digital-strategy.ec.europa.eu/en/policies/eu-age-verification

From my understanding it works as follows:

  • There will be a central "authority", with which you can identify
  • This authority will provide you with tokens indicating you are 18+ (or whatever age verfication you may need)
  • These tokens are stored locally, and contain no identifying information other than a simple "is this guy 18+?"
  • You can use these tokens to verify age with a website that requires age verification

This solution does seemingly address my two greatest concern with online age verficiation:

  • You cannot trust the website, so they only get the information they need. They don't get any identifiable information
  • You cannot trust the authority, so they don't get to know for which websites and for what reason you request 18+ tokens

Assuming that this blueprint is followed, it seems like a decent approach at online age verification.

Personally I have two problems with this :

  1. Can't those tokens be used for cross-site tracking ?

But more importantly :

  1. I don't care if the implementation is technically perfect. I refuse to verify my age on principle.

This authority will provide you with tokens indicating you are 18+ (or whatever age verfication you may need) These tokens are stored locally, and contain no identifying information other than a simple "is this guy 18+?"

So they're reusable? One token can be used for multiple age checks, right?

If not, then think about what that means.

  1. The token gets sent back to the authority for revocation.
  2. The token is authorised by the central authority as still valid.
  3. The token is uniquely identifiable
  4. The central authority knows who it issued each token for
  5. The central authority knows who has asked it the verify age.

Sure, the company you're purchasing from may have no new information, but the central authority now has everything it needs to know:

  • How often you buy tobacco, alcohol or medications
  • What discussion boards you are a member of
  • Have you purchased anything age restricted from any store (e.g. propane from a DIY store)

Not sure that's necessarily true. I don't see why it couldn't work like this:

  1. request personal token from authority. it works similar to a certificate chain, your token is derived from a central certificate
  2. you store your token locally
  3. you visit an age-restricted website. you send your token (or a challenge encrypted with that token) back to the website
  4. the website verifies your token with the certificate from the authority, (like how literal Certificate Authorities work) . the CA doesn't know when or why your token was used.

(fwiw I am sure governments will try their best to make this process less private)

[–] wewbull@feddit.uk 2 points 14 hours ago* (last edited 14 hours ago)

Your step 4 will make the token reusable, or at least reusable within a time frame. If a token can only be used once there has to be some information flow back to a central approval authority.

[–] Dsklnsadog@lemmy.dbzer0.com 105 points 1 day ago (4 children)

I get why this sounds better than websites directly collecting IDs, but I think it still understates the problem. Even if the site only sees “18+”, the system still begins with strong identity proofing somewhere upstream. So this is not really anonymous access, it is identity-based access with a privacy layer on top.

The bigger issue is centralization. You still need trusted issuers, approved apps, approved standards, and authorities deciding who can participate. That means users are being asked to trust a centralized framework not to expand, not to abuse its power, and not to fail. History gives us no reason to be relaxed about that.

I am also skeptical of the privacy promises. These systems are always presented in their ideal form, but real-world implementations involve metadata, logging, renewal, compliance rules, vendors, and future policy changes. “The website does not know who you are” is only one small part of the privacy question.

So even in the best-case version, this is still dangerous because it normalizes the idea that access to lawful online content should depend on credentials issued inside a centrally governed identity ecosystem. Today it is age verification. Tomorrow it is broader permissioned access to the internet. That is why I do not see this as a decent compromise, but as infrastructure for future control.

[–] fluffykittycat@slrpnk.net 24 points 1 day ago (1 children)

Also once they get their foot in the door, they can remove the privacy next time they want to unmask someone online saying "I support Palestine action"

-"You want to crack down on dissent? We got a token for that."

Apple or something.

[–] myplacedk@lemmy.world 6 points 20 hours ago (1 children)

I do see your concerns as valid. But at least in my country, we already have all of that.

I have an app I use to id myself to all sorts of stuff. Almost all of us has that. All the changes you mention are not changes, we have already had that for years. The new thing is that you don't give your id to the website.

Just like during the pandemic, we had an app to prove our vaccination status, without revealing id. Before that we had to prove id, and then they looked up vaccination status.

[–] Valmond@lemmy.dbzer0.com 1 points 12 hours ago

Sweden or Estonia?

[–] linule@lemmy.world 1 points 20 hours ago* (last edited 20 hours ago)

As far as I understand, there’s no need for “verified apps”. The third party just verifies your token with the emitter.

[–] kent_eh@lemmy.ca 23 points 1 day ago (2 children)

The big problem is the trustworthiness of that central authority to maintain the confidentiality of your information, and to not use it for other purposes.

[–] myplacedk@lemmy.world 3 points 20 hours ago (1 children)

The central authority is basically my government. They already know.

[–] wewbull@feddit.uk 3 points 17 hours ago (1 children)

They already know how often you do all the things you have to be over a certain age to do?

I don't know how the system works, but that is definitely not how it's supposed to work. I would not like to use a system like that.

[–] fluffykittycat@slrpnk.net 7 points 1 day ago

Which they of course will not.

[–] avidamoeba@lemmy.ca 29 points 1 day ago

This is the intelligent non-invasive way to implement this. Basically using a similar cryptographic signing scheme as SSL certificates. We've known how to do this for decades.

[–] LodeMike@lemmy.today 25 points 1 day ago

Hi. This system doesn't have the cryptographic properties that you think it does. The authority could keep a map between tokens and real IDs. They just say they don't.

[–] brokenwing@discuss.tchncs.de 15 points 1 day ago (1 children)

See the problem is the central authority.

[–] Humanius@lemmy.world 4 points 1 day ago* (last edited 1 day ago) (2 children)

I don't see a central authority (i.e. your government) issuing tokens, as much different from the government issuing you a ID card by which you can verify your age to buy alcohol in the supermarket.

As long as that central authority doesn't get to know what I use the tokens for, it seems like an acceptable solution to me.

[–] deathbird@mander.xyz 4 points 21 hours ago

Too me one of the big issues is being able to trust a government or business to not trace a person's identity back through the token. There are technical ways to prevent that as far as I'm aware, but there's such a strong incentive against such protections that it's really hard to trust unless you're technologically skilled enough to verify the process yourself.

[–] Senal@programming.dev 21 points 1 day ago* (last edited 1 day ago)

The difference is in the potential for creep.

The proposed implementation would actually be less invasive than a national ID card (assuming the implementation information provided is complete and accurate), but also usable in less scenarios.

AFAICT there is no provision for actually verifying the person using the app is the person who's identity is verified in the app.

What's to stop one person having a verified identity and just sharing it with the people around them once it's been issued ?

As an example, with an ID card in a bar you need to match the photo, this digital system would be like turning up to a bar with an ID that had no picture or details on , but just said "over 18", you could then hand this to a friend and they could also use it.

I personally think that if a system is mandatory then an easily circumventable verification system is the best choice , but such an easily circumventable system is exactly the kind of thing governments have used as an excuse to push for further encroachment.

Take the UK for example, the online safety act they have is easily circumvented with a VPN (which many people noted before it was implemented) the government basically stuck their head in the sand and claimed vpn's weren't widespread enough to be a problem.

Skip to now and they've got representatives looking to force vpn compliance with the online safety act without having the slightest clue about why that wouldn't and can't work the way they want.

A more suspicious person might suspect the attack on vpn usage was an expected part of the overall plan.

Even a less suspicious person could still see the direct line from one to the other.

I'm not saying they will, but if i were a betting person, I’d certainly put some money on it.

[–] Lemming6969@lemmy.world 3 points 1 day ago (1 children)

We should not care about verifying age.

[–] 5gruel@lemmy.world 1 points 15 hours ago (1 children)

wdym? in general? on the internet?

bc that's a hard disagree from my side as a blanket statement

[–] Lemming6969@lemmy.world 1 points 14 hours ago* (last edited 14 hours ago) (1 children)

Protection from media at the government level should not happen, that's the slippery slope. Very few policies aside from educate children about topics, has ever actually helped a child. This shit is about data and overlord control. Devices should not have age verification.

Very little good comes from arbitrary control, particularly based on age, and always has been that way even on other topics that are age restricted. Education is a far more effective means, and doesn't trample everyone.

[–] 5gruel@lemmy.world 1 points 9 hours ago (1 children)

Thanks for clarifying.

For the record, I think this mechanism is indeed far reaching, simply because the current criterion of "age" is arbitrary in the proposed mechanism.

Not sure if the "just education" part is realistic, though. The whole point is that children cannot make responsible decisions like adults can. We accept that for driving, sex, drugs and weapons.

[–] Lemming6969@lemmy.world 1 points 8 hours ago

Agreed they make irresponsible choices sometimes, and we can think that policy can protect them, but we have no control over most of those choices when it comes to seeking behavior. Driving starts at early teens a lot of places anyway, and cars can be stolen, and the cost barrier to entry is super high. There're other separate regulations about weapons, and kids with weapons are already getting them from an adult or stealing them, barrier to entry is high for purchase. Sex you absolutely cannot control and thinking you can is absurd for germane topic of seeking behavior, barrier to entry is effectively zero. Drugs are illegal or stolen from the start so moot point.

The only way to really curb any of these seeking behaviors is to educate the child and give them some experience with it. Enforcing age barriers doesn't really work much for these, why would digital age barriers do much for media or anything else? You make responsible people out of children by educating them and giving them responsibility experience to make better choices, and some will always have seeking behavior and age checks don't really stop them... It just invades the privacy of the rest of us.

[–] rozodru@piefed.world 6 points 1 day ago (1 children)

but whose the "central authority" that you have to provide your ID to? and what happens when that central authority inevitably gets hacked?

[–] Humanius@lemmy.world 12 points 1 day ago (1 children)

That central authority would, from my understanding, be your government. They already have your information, so if they get hacked you are already screwed ;)

[–] Scrollone@feddit.it 3 points 20 hours ago

But they could easily keep track of all the tokens they issued to you, and match them with services you use.

This has never been about protecting the kids. This is about mass surveillance.

This actually sounds pretty reasonable. Thanks for bringing it up.

[–] Airfried@piefed.social 2 points 1 day ago

On one hand this is an elegant solution that is already in use in Germany for years, if companies want to implement it that is. But I think only Sony's Playstore uses it. Or so I have heard. No US company wants to use it and I am sure they will lobby to get more data from users than a token if this gets rolled out EU wide. I am skeptical about this.

[–] Dagnet@lemmy.world -3 points 1 day ago

Could even have an OAuth flow that only provides a service unique key that the service can use to call the central authority to confirm the user is 18+ and nothing else, I always thought this would be the second best solution
