Age verification as a technical concept can be done in a privacy-preserving manner! Whether or not we want age verification is another debate, but let's stop making wrong technical claims about that: it doesn't help.
At some point someone will need to issue a key, which at some point will need to be verified against known good signatures.
These signatures will also need to be kept in case of lawsuirs/enforcement, so if somebody gets access they will know you visited that site
For example, imagine you put the same private key into the 'secure element' of every single iphone. You use code signing so that key is only unlocked when the phone is running unmodified iOS with all security updates. You use encryption and remote attestation for the front-facing camera and face id depth sensor. You use NFC to read government-authenticated age and appearance data from biometric passport chips (or digital ID cards) and you store it on-device.
Then, when you want to access pornhub, they send an age challenge to your device, your device makes sure your face matches the stored passport, and if so it signs the challenge with the private key.
Pornhub gets an Apple-signed attestation of age - but because every phone signs with challenges with the same private key, Pornhub can't link it to a particular phone or identity document.
So in a very narrow sense, privacy is preserved.
You can't use someone else's ID, as it checks your face every time. You can't fool it with a photo of the person because of the depth sensor. You can't MITM/replay the camera/depth data because the link is encrypted. You can't substitute software that skips the check with a rooted phone because of the code signing. Security holes can be closed by just pushing a mandatory OS update.
Sure, it doesn't work on PCs. Doesn't work on Linux, or on unlocked/rooted phones. It hands users' government ID documents over to Google and Apple. It requires people to carry foreign-made, battery powered, network connected GPS trackers (with cameras, microphones and speech recognition) with them. And there are non-negotiable terms of service everyone must agree to. But if you define "privacy-preserving" to ignore all that stuff and only consider whether Pornhub learns your identity, it's privacy-preserving.
Also even if it doesn't get leaked directly, the security of TPM chips is not absolute. Secrets from them can theoretically be extracted given an attacker with sufficient means and motivation. Normally nothing that's on a typical TPM chip would warrant a project of that magnitude, but a widely used private key can change that equation.
Plus a TPM chip doesn't really have means to tell the phone isn't being lied to. You could swap out the actual phone camera hardware and sensors for a custom board that feeds the entire phone camera data of your choosing and it would be none-the-wiser.
There's not necessarily wrong. Despite the vapid and damaging nature of most popular online media, isolating a child from it might have even worse social consequences when their real-life peer groups discover that they're not on social media or that their parents have neutered their phone. Some kids would turn out fine after that. Others would be socially destroyed for life (maybe with the right therapy they could become well-adjusted, but high quality therapy is rare).
No, they are a solution for parents who want to use them, and that's all they should be. Their existence demonstrates that it's possible to handle this without regulation, other than the desire of some people to inflict their preferences onto other people's kids.
Do they work currently? Not really
Are they too complex for the avg joe to work out. Unfortunately yes. (Something about the smartest bears and the dumbest humans)
The problem is that while you might be able to trust the crypto, the government won't trust you to do the crypto entirely by yourself. And this introduces avenues for deanonymisation. Moreover, collusion between the government and the entity making the age check can also theoretically deanonimize.
It's a complicated problem.
We continue to seek a technological solution to a parenting problem.
Then it's technically possible (and really not that difficult) for states to provide a service that issues zero-knowledge proofs of facts like "age > X".

so while this comment is apt, i would ask them what they think of the previous chicxulub impact of the 2012 era collusion - which to this day has not been reported on
(just realized emacs bindings work in comments, nice, no ctrl-x tho)
Is this speculation, or has it been confirmed somewhere?
Not that I really can tell what this was devastating to. Maybe United States v. Apple (2012), where Hachette Book Group, Inc., HarperCollins publishers, Macmillan publishers, Penguin Group, Inc., and Simon & Schuster, Inc. conspired with Apple to raise ebook prices?
I don't think it's that, because the Wikipedia article makes it seem like it was a force for good, but at the time, it wasn't certain at all that it would be that way.[1]
Beyond that, I'm not exactly sure what might be meant.

It's possible this scenario is acceptable to them because it means they can still tie your access to something that's easier to ban without requiring a full account login.
That's possible... and they might change their mind if so, we will see.
I feel like it's a similar issue to when scrapers pretend to be an allowed-origin webpage in order to abuse "public" API keys for web services.
They could also require the mobile device to interact with the requesting webpage in some manner, similar to mutual PIN/codes for Bluetooth/TV pairing these days. That way bulk sharing of the codes would still require active participation from the device that requested it in the first place, likely with a short time limit.
Also, if the implementation is competently done the phone will show the website for which you scanned the QR code. A user would be able to see whether or not that matches the site where they observed the QR code and proceed accordingly. In time Google will probably integrate it into the Chrome browser where a proxied QR code cannot even be shown.
At which point you should contact your attorney general, and work to ensure such efforts face legal challenges at every turn.
As for now, when I need to travel to Germany, I just book tickets through the national carrier of my home country, which for cross-border tickets often turns out to actually be cheaper than booking through DB. Thankfully I don't live in Germany proper and my need for travel there is not that high (once or twice a year at most) but I wonder what would I do if I had to move to Germany and use trains there more often.

We detected unusual activity from your device or network.
Reasons may include:
-Rapid taps or clicks
-JavaScript disabled or not working
-Automated (bot) activity on your network (IP X.X.X.X)
-Use of developer or inspection toolsNot solved at all: 99.999% of users don't give a damn and use a Google-signed Android.
My opinion is that because they don't give a damn does NOT mean regulations should not protect them. What Google is doing here is anticompetitive and they should be fined (antitrust and all that).
You could try handwriting and posting a letter to their CEO. I think that sometimes works. Probably not very often but there are more than zero CEOs who read those letters.
I was thinking in the same terms: you put up a QR capcha, you don't get my traffic and money. Just the amount of extra work needed, let alone the Google tracking turns me off. As if traffic lights, crosswalks and bridges weren't enough of a hassle.

Most human visitors will never ever notice the change. reCAPTCHA is completely invisible for most human visitors because they are allowed to pass just by fingerprint.
It's not like an average user is going to have to scan a QR code every time they visit a site via web browser. If it were like this then it would be a non-issue because no sane website would adopt this system. But it isn't.
On the opposite, if they see reports of many visitors not completing the captcha, they're likely to think "Wow so many bots!!! This defense nowadays is indispensable..!".
Sometimes you need to pass a captcha even to contact them (if you want to tell them that you can't pass their captcha).
So every government website. Every website where people simply have no choice (DMV) or where failure to login results in them not claiming the money/benefits they are due (all tax websites). And every website handling post-sale complaints (Airlines, insurance).

> No recent changes, but we do sometimes turn captchas on for logins when HN is under some kind of (possible) attack or other. That's been happening for a few hours. Hopefully it goes away soon.
However much I hate it, right now among the sites using reCAPTCHA there are many that I strongly want to use.
Let's find a better solution please
Is there an argument here that Google is creating a monopoly?
Could this be challenged on similar grounds that forced Microsoft to recommend other browsers to users on Windows?
Our antitrust laws have been toothless for decades, and both parties love billionaires controlling the rest of us with an iron fist.
GrapheneOS is looking more and more worth the headache that my limited free time generally does not like. I don't need Google to know my smut fanfiction is written by my IRL.
However he's been on it now for months and every time he shows me something on it I get a little more jealous. Everything seems to be working fine, including e.g. bank apps, and he has interesting features like some kind of app zoning thing limiting permissions on a zone to zone basis.
The only problem is it's only available on massive phones without headphone jacks and SD card slots, so I'm sticking with Xperia for now.
No. Bigger problem created, since there are innumerable government, health care, and educational web sites that use reCAPTCHA.
I'm not going to give up reading the test results from my doctor because of some simplistic ideologue decides that it's "problem solved."
CF turnstile is one, but of course that means Cloudflare owns even more of the web.
HCaptcha is inaccessible and actively discriminatory against individuals with disabilities and refuses to change, to the point that I suspect the only way that they will do anything is to file a class-action against them and sue them into the ground.
And I... Can't think of anything else. Other than to just get rid of Captchas entirely.
Enough to make it so bots are expensive to run.
People do care about such things.
I hope the same is true in other EU countries.
Suddenly I have been made aware that, having lost my paddle on Shit Creek, I will eventually be taken downstream to Shit Lake (where it appears I will inevitably drop anchor).
You could just call them.
But in all seriousness, many services are making it difficult through to impossible to communicate outside of their web or app platforms. Call centres are expensive and messy, and it's now apparently acceptable as a society to treat customers/clients/whatever as adversaries so they can get away with making it hard to communicate with them.
Edit: aaaand... That's another little sliver of my faith gone : https://www.theatlantic.com/podcasts/2026/04/how-fake-people...
Note that they do not mention any specific companies on that landing page. That is pretty intentional.
But realistically going after bots is expensive and rarely successful, so most companies don’t do it. Even if you find the guy, the chances they can be legally reached are pretty low.
Because they don't care. It doesn't matter that it's AI slop, it generates views. And Google and Meta can bill advertisers for those views.
Zuckerberg is paying people to put AI slop Shrimp Jesus on facebook. (Not directly to platforms like this, but with the incentive structure)
Really, they're not just cashing in on the views of AI slop being put in front of boomers. They're cashing both ways; While the low end spam industry is merely guessing and iterating on whatever generates views, the more refined spammer does not leave the performance of their latest slop post up to chance, and just uses good old viewbotting. Viewbotting that these days, is mostly done on real devices. Which show ads, to the bots or underpaid developing world workers. Google and Meta'll still charge you for those impressions though.
The losers? People who sincerely try to use these platforms, and whatever idiot businesses are still paying for ads by the impression or click, rather than conversions that immediately generate revenue.

Also $1,500 a month for 10 "influencers" is wild. This doesn't seem that sophisticated unless they're doing something special to increase trust scores of accounts. They say they have "in house warming algorithm" which honestly doesn't inspire confidence for me.
Whats funny is its almost a certainty (if they are doing things correctly) that they have literal farms of phones (probably in SEA). The only real way to keep trust high is to have a real mobile connection and unique devices. Proxies are okay, but you really need to use the apps on real hardware.
The cost is the attestation keys of a real phone. Once it gets burned, the phone is useless to them.

Probably a decent amount of compute cost for video generation, but I'm sure they have access to free compute and inference for being in bed with a16z.
Yes, somehow "parse this QR code" would not have made my top 500,000 list of 'tasks that a human can do more effectively than a computer'.
I think it's most likely to be attested by Google remotely; they might be using an app (with enormous access to the phone as the Play Services have) to be able to link a ton of data together, possibly including the local activity on the phone, officially to make better humanity assessments based on it all.
For people using a Google account it probably won't make a huge difference, in terms of data collected.
If that's how it would work, spoofing would probably be theoretically possible, but it would be easy for Google to detect attestations used by multiple people.
Let's not forget that this is an update to a very approximate system, absolute security is not (yet) required.
But there's a good chance that it will be extremely hard to sidestep, despite that.
Doesn't Play Integrity use hardware attestation, but specifically checking the Google keys?
If you use the Play Services on GrapheneOS, you still don't pass Play Integrity because your system is signed by GrapheneOS and not by Google.
But anything your phone can possibly do in software can be spoofed, so how would that help?

It's funny how people after all this time think 99 Articles, 173 Recitals and a huge tech lobby equals a water-tight, pro-citizen, impenetrable privacy law with almost no exemptions.
