Please stop saying "Brussels" to mean the EU. It's a nasty trick to give the idea that it's some kind of external entity forcing your country to do something. It's not. It's an assembly. And it's insulting to people from Brussels. I don't want this any more than you do.

It’s very common throughout English. The Russian government is refered to as Moscow, US as Washington. It’s the same and doesn’t refer to residents. It’s known as synecdoche.

In other words, sorry but it’s here to stay.

No, it is not quite the same as Moscow and Washington are capitals of centralised states who give orders to the whole nation.

The EU on the other hand does not have a common constitution, army etc. so is not a real state (yet). It is made up of soveraign nations who come together debate and decide there, but then it is still up to the members to implement that.

So the transition to the EU as one state is happening, but might never complete.

The European Commission is in fact empowered to boss member states around, it's one of the things that give EU law teeth rather than it being like "international law" (unenforceable anarchy). It also acts much like a government (in the sense of executive, not in the sense of state) when it comes to EU lawmaking, and has various government-like powers in fields like competition law for example. And the European Commission is based in Brussels. Saying "Brussels" to refer to Commission activity is as natural as saying "London", "Downing Street", "the Cabinet Office", "Whitehall" etc to refer to British government functions. And that's without getting into all the other EU institutions that are based there!

It is true that the EU institutions are ultimately subordinate to the member states in a way that, say, the US federal institutions are not, but the EU is still very much is its own thing. It even has legal personality these days: you can sue the EU and the EU can sue you.

The problem here, and the source of OOPs annoyance I think, is that the governments of the constituting member states have the habit to present unpopular regulations as 'from Brussels' while taking credit for the popular things as from 'Den Haag','Berlin' or 'Paris' or whatever the local capital is. This habit is the main driver of anti-EU sentiments across the whole of europe. Which is a pity, mainly because it takes the attention away from highly needed reforms in the EU structures because people who could drive the reforms now just want out.

So while linguistically it's the same system as using 'Washington' or 'Moscow', Brussels is specifically in the bad spot where it gets blamed for impopular stuff but never praised for popular things.

Brussels is the seat of five governments: the city itself, the Brussels-Capital autonomous region, the Flemish Parliament and Government (luckily the Wallon Government seat is in Namur), the Belgian Federal Parliament, and the European Commission and Parliament.

imo: mostly because the Author wants it be a disaster.

The App has not launched, they published the source code in order to invite external review. I dont have time to every claim, but e.g. this [see quote below] seems to be blown out of proportions to me - the app fails to delete a temp. image, which results in a selfie being stored indefinitely(?) on the internal disk of your device - if an adversary has access to the internal disk of my phone, they can also just access the photo roll.

"For selfie pictures:

Different scenario. These images are written to external storage in lossless PNG format, but they're never deleted. Not a cache... long-term storage. These are protected with DE keys at the Android level, but again, the app makes no attempt to encrypt/protect them.

This is akin to taking a picture of your passport/government ID using the camera app and keeping it just in case. You can encrypt data taken from it until you're blue in the face... leaving the original image on disk is crazy & unnecessary."

Not immediately deleting the selfie is a pretty fundamental and egregious mistake to make. People are particularly sensitive to selfies not being handled correctly after Discord lost thousands of them, despite promising to delete them after age verification occurred (and then not doing so) https://www.bbc.com/news/articles/c8jmzd972leo

The damage is limited because the selfie is only retained on device, but it still does not signal competency from the EU to fail at the most basic hurdle of disposing of the selfie once verification is complete.

jimmydorry 3 hours ago|||
>Discord lost thousands of them, despite promising to delete them after age verification occurred (and then not doing so)

This is misleading, yet everyone seems to repeat it. Discord's implementation of ID verification did not retain IDs. Reporting on this was so poor, but what appears to have happened was that people that failed age estimation / ID checks had to raise a support ticket and get manually reviewed. That support platform was pwned and the active support tickets were leaked. Who knows how long these support tickets were set to live for, but up to 70,000 active tickets getting leaked feels like a drop in the bucket. It's also not immediately clear to me what the alternative is (other than not getting hacked), when you require human intervention to review problematic IDs. Even if the ID only lived on their server for 24 hours during manual review, across a userbase of >200 million users, that's a lot of IDs at risk at any given moment, especially during these initial roll outs of age verification.

deminature 1 hour ago||
This is a distinction without a difference. Users were assured their selfies would not be retained and they were. Discord then proceeded to lose those selfies to bad actors, after promising not to retain them. The incident has caused enormous distrust of all age verification systems, which were already starting in the mind of the community from a base level of skepticism. It's already highly invasive to take a photo of yourself, but then the user must trust that the organization on the other end will handle it appropriately. To have that trust so conspicuously broken poisons the well for all other age verification systems and websites that are legally compelled to use it, or face penalties from aggressive organizations like OFCOM.

Note that this is an implementation of eIDAS:

https://www.eudi-wallet.eu/

The point of this is that you can use the credentials on your phone to prove that you are an adult to a website using zero-knowledge proofs to avoid disclosing your identity to anybody.

If somebody who has access to your unlocked phone can access the data in the app, then this is something that should be tightened up but it’s a substantial privacy improvement over the far more commonplace option of uploading your ID to every website that wants to know if you are an adult.

It’s an attempt to avoid things like this:

It is my understanding that this is not possible. I would be happy to be shown to be wrong, but to me it seems like you can either prevent people from lending out their credentials, or you can preserve the anonymity of the user, but not both.

You can use 0KP to prove you have a signed certificate issued by your government that says you are an adult, but then anyone with such a certificate can use it to masquerade as however many sock puppets they like and act as a proxy for people who aren't adults. You can have the issuing government in the loop signing one-time tokens to stop Adults-Georg from creating 10k 18+ attestations per day, but then the issuing government and the service providers have a timing side-channel they can use to correlate identities to service users. Is there some other scheme I'm missing that solves this dilemma?

This is not designed to prevent adults from coöperating with minors; that makes no sense as a design goal because any technical measure can always be bypassed with “download this for me and give me the file”. This is designed to prevent minors from being able to access systems without an adult.

Nothing prevents an adult from buying alcohol on behalf of minors; that doesn’t mean laws that prevent minors from directly buying alcohol are useless.

snackbroken 18 hours ago||
But laws against selling/giving alcohol to minors are moderately successful at curbing teen alcohol use because they carry with them a risk of punishment that grows with the scale of the operation. If all it took was one adult who thought "kids should be allowed to drink if they want" to provide all the kids in the country with free booze and that adult had no meaningful fear of repercussions, the laws would be nothing but sternly worded advice.

If the proof of adulthood scheme is truly anonymous, one adult with some technical chops who thinks "kids should be allowed to watch porn if they want" would be able to, say, run an adult-o-matic-9000 TOR hidden service that anyone can use to pinky promise that they are an adult without fear of repercussions. If such a service comes with a meaningful risk of being identified and punished, it is by definition not anonymous.

I suppose I'm just not convinced giving up some basic liberties for a law that converts into sternly worded advice if just one adult chooses to break it is a great idea.

It's always fascinating when people put "tor hidden service" in a sentence that describes something that will reach millions.

I also don't think you'll find many ISPs terribly keen to fight for the neutral treatment of TOR connections when the reason for this fight is explicitly to serve porn to minors.

In Europe it’s very frequently perfectly legal to give alcohol to minors, but not sell.

For example, in the UK it’s only illegal to give alcohol to a child younger than 5 years old.

France has no limitations, giving a toddler wine is not explicitly illegal. Getting a child drunk would be.

The certificates in question can use a few mitigations: short lived, hardware stored (in a TPM, making distribution harder), be single use, have a random id which the service being accessed can check how many times has been used.

> but then the issuing government and the service providers have a timing side-channel they can use to correlate identities

That's not reallya concern, IMO. That would always exist as a risk - most people would probably have a flow of trying to do something, having to prove ID/age, doing that step, continuing with the something, which means you'd probably be able to time correlate the two sides quite often. The solution here is legal with strong barriers, not technical.

actionfromafar 1 day ago|||
Can attestations be rate-limited or is that the timing side-channel you are talking about?
snackbroken 22 hours ago||
Precisely. To rate-limit attestations you either need government somewhere in the loop so that they get notified and can revoke certificates when they detect abuse (but then they can correlate requests to prove adulthood with the service provider), or you need the proof of adulthood to be tied to the certificate in some way that the service provider can tell if a certificate is being re-used. But then anyone with a copy of all the certificates (read: the government) can re-run the proof on their end and figure out who is who.

Can you give a brief explanation of how this is done with a zero-knowledge proof? That site is low information and painful to navigate, and it seems quite surprising to me that this is possible. ID verification, in the government sense, is ostensibly going to require matching an ID against a some other resource. If done locally then you can trivially spoof the result, akin to hacking a game, but if done remotely then it's not zero-knowledge.

I think a zero-knowledge system here would be quite desirable. But a centralized repository that is e.g. maintaining tabs on every single adult-authorization for every single person with verifiable details of them is, by contrast, a dystopic disaster waiting to happen because it will be hacked, leaked, and abused, sooner or later.

Most countries in the EU already have widely accepted identity proof apps mostly verified by the banks or the government itself. Once verified the identity app gets a certificate which is signed by the authority which issues the identity. We all know how that works as that’s how TLS works as well. The zero proof age check is based on verifiable credentials and the related verifiable presentation. Once you have a wallet with your identity it’s not hard to issue cryptographic proofs of some properties of your credentials, and age is a property of your identity credentials basically. To learn more about the technical details, search for the specifications I mentioned above: verifiable credentials, verifiable presentations.

Ah, and the sites (or whatever else) can then verify the key is valid locally? Assuming that is the case, that'd make for a surprisingly nice system, further assuming that the produced credential is not reversible.

You're both right.

Without exposing my citizenship, I was able to use by EU-nation issued ID to confirm only my year of birth.

The website supported this country's national ID login method, in the login challenge asked the server to provide my age, before I signed in to confirm (scanning qr code with my mobile app) I was informed what data was requested, then I consented to them confirming my data.

Not very sensitive things work without my physical ID present, sensitive have additional step with me providing my physical ID (to the NFC reader) and unlocking my key (stored on the ID) with a pin.

All in all it's really very sensible and fast.

Even better would be if the website provided the age rating in a HTTP header, and the browser could locally check if the account is allowed to see it. That way you avoid exposing the age of the user.

And yes, even sending an age bracket exposes the age over time as you can observe a repeat visitor changing brackets and compute the actual age from that. With the server sending the info instead you can't really tell if the browser blocked it, or if the user just didn't navigate further on the page. (The browser still need to fetch all the CSS and other resources though, otherwise that would be possible to tell apart.)

That doesn't make sense, all IDs are already in a single government database. Kind of by definition in fact, for IDs to be useful they need to be emitted by a central authority with associated security and revokability guarantees.

The implementations I've seen rely on an app reading your physical ID and its NFC chip, comparing that with a selfie to ensure it's the same person, and being able to provide anonymous proof you are of age based on that, or proof that you are indeed who you say you are.

The main issue appears to be that as per the blueprint user MUST use one of the mandated handsets (iPhone or Android with pre-installed and privileged Google Services) and:

- MUST use either Google or Apple account - must not be banned by the provider or sanctioned in the USA

These issues have been flagged to the devs working on the blueprint since the inception, only to be handwaved away.

Getting banned can happen randomly even if you're not doing anything illegal or wrong (it's enough for a robot to decide you're within the blast radius), getting sanctioned can happen if you're an UN lawyer investigating human rights abuses USA actually likes.

No it isn't.

Literally that is not the scope document, and such a solution would not be permitted by the EU as compliant with the legislation.

The app isn't zero knowledge. A prototype workflow has been designed for a one way transfer to sites that is zero knowledge, but it doesn't actually deliver zero knowledge because it you have to verify your age with an external provider to get the credential (which is not zero knowledge), the app has to be secured with either Apple or Google's attestation services (which are not zero knowledge), and the site has to be able to check with the original external provider that the credential hasn't been revoked (which is in no way zero knowledge).

ptx 2 hours ago|||
The online version has been extended quite a bit beyond what we broadly agree. If we translated back to checking ID in shops, it might look more like this:

1) Obviously you can't be trusted to handle your own ID card, because you could lend it to someone else or manipulate it in some way, so there should be a trusted guard with you at all times to manage your ID card for you and hand it to the shopkeeper.

2) Obviously you can't be trusted not to try to influence or attack your guard, so you must be kept in handcuffs for your own safety.

3) Obviously you can't be trusted with acquiring unapproved tools or meeting unapproved people who might enable you to break out of your handcuffs, so the guard must only allow you to communicate with approved people and buy approved products.

Conveniently and profitably, this also puts the company supplying the guard in a position where they can sell access to their control over you (as a consumer and as a source of experimental data) to their trusted partners.

Showing my ID at the store doesn't register this on a government OpenID4VP server, and the store doesn't copy my ID.

This is not the problem the title makes it out to be.. It's still in development.

> "Now, when we say it's a final version, it's ... still a demo version." He added the final product is not yet available for citizens and "the code will be constantly updated and improved … I cannot today exclude or prejudge if further updates will be required or not."

The whole idea of this age requirement is ridiculous in the first place, changing the focus to how good or bad the unnecessary tools are is nothing but a nice distraction.

The title of the original article seems wrong, they didn't launch the app, they published the source code ahead of the launch.

There's something that is written between the lines here.

EU is often portrayed as overly bureaucratic, slow moving. The way this app was developed seems more in the line of "move fast, break things".

I don't know if that says something about the EU, or about the EU-naysayers, but I thought it was worth pointing out.

1. Devs forgot to delete images in some failed scenarios. Images that do not get sent anywhere and remain locally. In an open source app that anyone can point calmly to the bug and it will get fixed easily.

2. "an attacker can simply remove the PinEnc/PinIV values from the shared_prefs file"... Any android developer knows that to access the shared prefs file you need ROOT access on the phone, which is impossible on the stock os. Rooting the phone requires advanced knowledge. It means deliberately nuking your phone security, which most likely will require factory resetting the phone in the process. Or a hacker would need to use a sophisticated exploit, maybe even 0day, to access an app that would allow him to log in on some adult sites. Sounds reasonable (no).

So, the guy found two very superficial problems in a early demo app. Does not even look at the important code with the actual implementation of the zero knowledge proof cryptography, as it is way above his skill level. Throws malicious allegations mixed with blatant lies. Cries for attention to the whole internet and it gets augmented by news and people who understand security and technology even less than him. He dares calling it "hacking" in under 2 minutes. That's just disgusting.

He even calls himself "Security Consultant". Lord have mercy on whoever is going to work with him.
