"Let’s say I downloaded the app, proved that I am over 18, then my nephew can take my phone, unlock my app and use it to prove he is over 18." - and how is that something that could, or should, be addressed by the app? Are we even serious??

When there's severe downsides to an measure to try to improve something else, the efficacy of it matters. This isn't about the app specifically, it's about the requirement for this kind of verification in the first place.

well of course because the whole reason you're making free men and women verify their identity with government-issued documents... was supposed to be to prevent that. If its not going to prevent such an easy work-around ITS NOT WORTH IT (not that it was in the first place)

Because people share phones with their kids. It's not rare or even mildly unusual. The problem isn't that the app needs to solve this. The problem is the app is useless, along with this whole bizarre "need for age verification" plot that poofed out of existence simultaneously around the whole globe mysteriously a few months ago.

Well, reality called and says: Like ID, drivers license, credit cards and guns: Phones are sth. you dont just "share" with your kids. Also there is an option to guard the ID App with an additional PIN/Biometric.
mrweasel 1 day ago|||
That's not reality for many of us. I don't consider my phone a secure device by any means. It has nothing on it that I'd regard as something I'd need to guard against my family.

I know a fair number of especially elderly people who want to disable PIN and bio-metrics from their phone, because they view it as a pain to deal with.

PINs can also be guessed or someone might look you over the shoulder and steal it that way. Many phones still doesn't have biometrics, or people don't want to use it.

Our realities might be different, but in my reality a cell phone, which you almost by definition brings with you out in the world, should never be considered a secure device.

Oh man, if the kid gets hold of both of their parents phones with login, they could divorce them. I don't have kids yet, so this might change, but I would not give them login and / or unsupervised access.

I don't think you can guess pins, as the phones locks after a few failed attempts.

You keep using the term “secure” that it sounds like you think education is like a prison sentence. You’re not doing this for security but for safety. A stair gate or drawer child-proofing lock are by no means secure but you use them anyway for the child’s safety.

You can’t just leave every dangerous thing out in the open because you “view it as a pain to deal with” storing them safely and then blame everyone else for the situation that follows.

Our realities might be different but in my reality if you put 0 (zero) effort to keep some critical things safely away from your child because it’s too much of a hassle to do it, or they’ll get around that anyway, etc. then you’re failing your children.

mrweasel 1 day ago||
You make it sound like having a phone in public is basically "open carry" which is absolute nonsense.

What do you have on your phone that's dangerous? Phones aren't safety device, and they shouldn't be turned into one.

close04 1 day ago||
You make it sound like you put no effort in understanding my comment and just followed up with whatever supported your view.

If you have anything on your phone that should be off limits to your child but make no effort to ensure that (give them the phone, no passwords, no supervision) because it’s too inconvenient you are failing the child. Can I put it in simpler words?

> What do you have on your phone that's dangerous?

I hope you were asking hypothetically.

For one, the phone itself since staring into a small screen at god knows what because supervising them is a chore is bad for anything you can imagine, from eyes, to posture, to brain development. But also a browser that can access anything on the internet (modern Goatse, Rotten, Ogrish, other wholesome sites like that). My credit card numbers. All my passwords. Hardcore porn. Facebook and TikTok. The app that delivers booze to my doorstep. 50 shades of grey (the book and the movie). X (Twitter), I left the worst for last. If you really think a completely open internet connected phone is perfectly safe for a kid at the very least you’re in the wrong conversation.

It doesn’t matter, the discussion is about age verification for things that a child should be kept away from, whatever that is. If you’re trying to protect the kids from anything, especially legitimate concerns, then you can’t expect some mechanism to magically do all that parenting for you. It can help but not be the parent when the parent thinks it’s too inconvenient to actually do some parenting.

I don't like the idea of a central authority determining what "my child should be kept away from" and then implementing Orwellian surveillance laws to enforce it. "For the sake of the children".

Seeing something scary, disturbing, or sexual on the internet as a child does not result in a maladjusted adult. These laws are about one thing and one thing only - furthering the global surveillance network.

Everything else is a smokescreen. Pretending that a phone or any Internet-connected terminal is something that should be kept secured and away from children is a parenting decision, not a policy one, and any attempt to justify it as a policy decision is toxic nonsense at best and astroturfing for the surveillance state at worst.

Well thank God this about a double-blind way to verify your age and not that.

thomastjeffery 13 hours ago||
The surrounding context is that. Why else would you participate with a government in an age verification system?

Maybe your argument is that it's not a surveillance state because it is implemented with a 0 knowledge proof. Sure, the age verification is, but that is only part of the system we are talking about. The rest of the system is the demand that every adult play keep-away with their verification, and every host on the internet (that can be adequately threatened) play, too.

The only way for this to be anything else is if every participant can individually decide what should and should not be kept away from children. Such a premise is fundamentally incompatible.

A phone isn't going to run off the road and kill 7 people. This is nonsense and you know it.

And yes, phones are something parents do "just" share with their kids because nobody is bizarre enough to look at a phone the same way as a gun or a car. It's the YouTube device that can talk to grandma. All you have to do to see proof that it's something people "just" share is to walk into a grocery store and look at parents pushing kids in carts while those kids watch videos. 25 years ago those phones were Game Boys. Nobody is seeing them as a gun. That's the most disconnected from reality take I've seen in my life.

Sweepi 1 day ago||
Whats the diff between today giving you phone to your 8-year and making sure /having trust that they do not use it to e.g. order a new toy from Amazon and tomorrow that he is not using to verify they are an adult? I mean, most things today (like accessing porn, buying alcohol) do not require any extra age verification. They can just do it using your phone/accounts.
kdheiwns 1 day ago||
Not everyone views their child as an enemy that just happens to be in close quarters with them. Most people trust their kids to generally not do bad things. People keep knives in their kitchen and kids, explain the danger, and kids are generally responsible enough to not play with them.

If this is a concept that you can't grasp, then words will never convey it. It's simply a detachment from reality to think people are viewing their phones as a loaded gun and their child as someone hellbent on betraying them and causing massive societal damage.

The phone is the YouTube device. If they get a notification that their kid ordered from Amazon, they'll cancel the order and tell their kid not to do it again. It's seriously that simple. Just go and talk to a parent. They'll think viewing their phones as a WMD is insane.

Other parents have different opinions to you about the value of this.
JoshTriplett 19 hours ago|||
The problem comes in when they feel their opinions should carry weight about other people's kids. There are very limited ways in which we should allow that, and to an oversimplified approximation, they boil down to "don't do kids harm that prevents them from becoming an intact person society treats as a human allowed to make their own decisions". And then the problem is that some people think some websites do such damage, and other people think some websites provide help to survive such damage.

Giving your kid a gateway to every bad thing on the internet is not life as usual. It's incredibly recent, and I don't have shares in SSRI manufacturers, so I don't like it.
saghm 3 hours ago||
Having a smartphone at all also is incredibly recent, so by that logic we shouldn't let anyone have them. Alternately, maybe we can recognize that they haven't been long enough for any specific way of using them to be the long-term universal standard.

In the meantime, I still don't understand why someone with no kids should have their access gated based on what opinions other people have on parenting. I literally don't have any stake in whether you give your kids access to your phone or not, and I don't make any claims that I would have any clue what the correct way to raise a kid is. That doesn't make it reasonable to have a policy that requires literally the exact people who aren't the ones that are ostensibly supposed to be protected by the system tracked by it.

JoshTriplett 1 day ago|||
Exactly. "Age verification" is the "think of the children" marketing campaign for "identity verification". Governments don't like anonymity; it makes it harder to find those they consider enemies. But it's hard to market something people don't want and get no benefit from. So, you dress it up in fear and make it easy to villify people who argue against it.

Stop with the scaremongering.

This is a reference app implementation that uses a detailed framework which explicitly has as a core tenet double blindness. The place you prove your age to has no idea about anything other than you being of age, and the thing you use to prove your age has no idea about where you're using that proof.

Why do I need to prove my age again?

On top of the pretty bad article, HN finds the “can’t win” scenario again. There’s no age verification scheme that will survive “collusion”, that’s when the adult allows the minor to use validated credentials, devices, etc. And whatever more intrusive age verification schemes we come up with will also fail this but add the intrusiveness to ruffle even more HN feathers. We can have the constant face, fingerprint and DNA scan for as long as the sensitive apps is used. Everything gets stored on a central server for safety so your kid can’t hack the device and replace the reference sample. /s

> "Let’s say I downloaded the app, proved that I am over 18, then my nephew can take my phone, unlock my app and use it to prove he is over 18."

Love the magic step in the middle, unlock my app. Ask for passcode or faceid to “unlock your app”. That’s a lot of legwork the adult has to do so the child can “trick” the system.

Some people will forever be shocked that if they leave on the table an open booze or medicine bottle, loaded gun, etc. a child can just take them and misuse them. The blame is unmistakably with bottle and gun manufacturers, right?

Put a modicum of effort to protect the sensitive apps or supervise the child when you share your device. They can do a lot of damage even with age appropriate apps. Wanna see how quickly your kid will tell everyone on the net how much money you have (via proxies), where you live, and when you go on vacation? Or tell someone the credit card number they swiped from your pocket if the other person makes it sound like a game?

The first premise you are avoiding is that a child can misuse a phone.

The second premise you are avoiding is that the government can define, for every child, what constitutes misuse.

You are advocating thought crime. You do not have my support.

My government cannot adequately manage responsibility for my cupboards. It therefore shall not have authority over them.

Cthulhu_ 4 hours ago|||
Your government does have various authorities over what you put in your cupboards though. like, you can't just put a gun in there (actually I don't know where you live but that's true for most countries). You can't just get in a car.

Anyway, ultimately it's best effort. No security is flawless, but if it stops 99% or more of cases it's better than 0%.

I replied to the content of the article and HN comments, not what you think I should have replied to. If anything you even failed to notice that I expect parents to do some of the parenting and not expect an app to magically do it all for them.

The government already defines what misuse is both for children and adults, defines responsibility for a lot of things even in your cupboard, and has been doing so for as governments have been a thing. And I don’t think you understand what “thought crime” is.

You won’t hear me say this too often but next time use an LLM to write your comments, any LLM will do, can only get better.

> "Let’s say I downloaded the app, proved that I am over 18, then my nephew can take my phone, unlock my app and use it to prove he is over 18."

While I appreciate the zero-knowledge proofs is considered, how the hell did no one in charge of the app design think of this? It's is literally the first question I asked when I first heard about this app. You go to the app in a store to buy alcohol, you're asked to verify your age, but that's not what you're doing. Your simply showing the store that you have a phone, with and app, which was configured by some over 18 (maybe).

Honestly I don't think it's possible to verify that you're over 18 without also providing something like a photo ID (and even that is error prone).

You can probably do something online, where the website or app does some back channel communication to a server that verifies a token. Even that is going to have issues. You could add a "List of sites that has verified your age" option where you can revoke the verification, in case your nephew borrows your phone.

They are going to implement this and it will be "good enough", but I don't see this being 100% secure or correct.

That's not what you're competing with. Your competing with a drivers license with a photo (not a great photo) and some countries have pretty easily faked drivers licenses, but others have drivers licenses in hard plastic with holographic features.

Not sure if you're joking or not, but Denmark have had people show an edited screenshot of the drivers license app, to get into clubs or buy alcohol.

I think they "fixed" it. I think it has some effect now that only works if you tilt the phone.

klausa 1 day ago|||
You're competing with that for "I want to make sure the person standing in front of me is of legal drinking age" use-case, but for the remote KYC/age-verification usecases, you're competing with a photo of the document and/or a selfie.

Maybe bundling these under the same system is a mistake and they should be separate systems with different considerations; it would certainly help with arguments about it online ;P
