It is crazy people think apple isnt on the side of privacy. Are they perfect? Not even close, but compared to the rest of big tech theyre simply on another level.

Apple could easily not do this stuff and it may even be easier to not.

> It is crazy people think apple isnt on the side of privacy.

> It also ensured pressure from governments and plaintiffs, including CSAM victims, who preferred Apple’s more interventionist approaches, which Apple had voluntarily demonstrated it was willing to do.

I feel that Apple open pandora's box with the client-side scanning. It proved that it was technically feasible, and was "privacy preserving". I use scare quotes there because I don't think that political or religious dissidents would find that the same or similar technology used to discover and persecute them is "privacy preserving". And that's really the problem with Apple here. They provided a model for scanning for any kind of message or material while purportedly maintaining privacy.

Didn't their paper disproved by reversing the perceptual hashes to reveal blurred version of the images being hashed, and Apple basically said "that's fair, it's not as robust as we wanted, let's visit this later"?

If not, I'll happily stand corrected, but please share sources.

Is it different than telling your therapist something in confidence and then finding police waiting for you in the lobby.

arcticbull40 minutes ago

Yes, in the sense that you have a legal doctor-patient privilege that binds what they can share with whom. There's not really an Apple cloud user privilege.

No, in the sense that your therapist is still required to report you to the police in various situations where you pose an immediate threat to yourself or others, etc.

I thought the client side scanning was to protect children? If it suspects an image is bad, it blurs it and pops up a warning including a link to resources to go to for help.

Very different than trying to narc out users to the authorities.

pavon24 minutes ago

That is what they actually deployed. They were planning on performing client-side scanning of all images uploaded to iCloud for CSAM and reporting it to the authorities, but backpedaled after public push-back.

Apple is very much like WhatsApp. Yes you cant perfectly trust their E2EE against state actors, but both in fact put some effort into making world have little bit more privacy.

At least on Desktop we have usable Linux, but on the phones there is literally nothing usable because thanks to Google efforts switching to GrapheneOS mean tons of apps either not working or break every few months.

Yes its possible to make Andoid spy on you a little less, but even for tech savvy person its damn inconvinient and Google making platform worse with every single release.

Thanks to Google "security" I can use my banking apps on 9 years old device with 6 years outdated firmware, but not on GrapheneOS.

Apple may be on the side of privacy, but since they are competing everybody out of the market with their slick consumer products they actually form a threat to privacy since now the government has to only implement a backdoor at one vendor.

Indeed.

But they are until they are actually defeated. I would rather plan for failure. We are in a global climate where court rulings can be ignored.

I was an engineer at both MS and Apple. At Apple, privacy was baked into every new feature from the start. At MS, the privacy component was glued on at the very end, if ever.

Like OP said, Apple isn't perfect nor will they ever be, but they do prioritize privacy better than most.

dd8601fn34 minutes ago

It's telling that these come from people trying to implement tracking and high visibility into user behavior, and complaining that Apple won't let them even though Apple conceptually could.

Except ublock, which can't do what it does the way it normally does, for the same reason you can't have any plugin inspecting realtime activity and doing scriptlet injection.

You can have ad blocking. You can't have plugins with that kind of low level access to your browser activity.

You can prefer something that allows dangerous behavior as a trade-off for greater capabilities, but you can't deny it's a safety trade-off where Apple picked what's safer.

I said this in another thread a while ago, and one of these people who thinks Apple isn’t on the side of privacy cited a lawsuit they settled around Siri listened to conversations: https://www.scientificamerican.com/article/apple-settles-cla...

People understood this settlement to mean Apple was spying on their conversations and selling them to advertisers, when it seems to have more to do with people accidentally triggering Siri. But people don’t care about this kind of nuance or actually tallying up all the ways Apple is pro privacy against rare issues like this one. It’s all just tribalism at the end of the day.

djoldman39 minutes ago

I am not a lawyer.

There is something ironic about US laws that attempt to prevent crime A by outlawing action B. For example:

  * A: physical sexual abuse of children. B: possession or distribution of CSAM
  * A: drug trafficking or tax evasion. B: structured cash withdrawals
The irony is that the more B is prevented, the less A can be detected and the less B can be used as evidence of A.

It's my understanding that conviction of CSAM-related crimes do not require any physical act to have ever occurred to any real person: one can be convicted of CSAM-related crimes related to paintings/drawings/created_art of fictional people.

It's my understanding that one can be convicted of structured withdrawals that are not driven by, linked to, or in any way related to anything nefarious.

pushcx11 minutes ago

No. In short, in US law, CSAM is a visual depiction of a real-world act of child sexual abuse. Visual depictions like you're describing are covered under a different law, and I'm not aware of it having a short name. There's a good expert thread on this with links to the relevant federal laws here: https://bsky.app/profile/rahaeli.bsky.social/post/3lbt7zkvlq...

ux26647823 minutes ago

> one can be convicted of CSAM-related crimes related to paintings/drawings/created_art of fictional people.

This isn't necessarily the case in the US, though I believe only for drawings. AI-generated CSAM probably wouldn't fly in a court of law.

Regardless, it's a naive conception of a system of law to think of it as a utilitarian system of restitution in contexts of "this individual harmed this individual". In fact, that would fall under the category of a "tort" rather than a "crime". The law is just as much about enforcing social mores and norms as it is about dealing with individuals harming each other. Hence why locales like Canada outlaw all forms CSAM, even fictional ones. The victim taken is to be society itself. The possession of this material, implicitly entailing enjoyment of it, is so gross a violation of society's norms and mores that it becomes elevated to a legal matter.

I don't think these are the same. Outlawing CSAM gives law enforcement the ability to shutdown markets and prevent commercial distribution of CSAM. Sexually abusing children is heinous, but sexually abusing children for financial gain is even worse.

carljungslabtek11 minutes ago

There are even people involved in commercial distribution of it that claim to not even be interested in children, just in profit or even allegedly “for a sense of community” (someone actually said this after getting caught, he was in his 20s but I can’t remember his name — he might have been one of the red room guys).

On top of that, while there are different types of child abusers, the worst ones almost invariantly collect CSAM to the point of hoarding. So it really isn’t that bad of a proxy.

The root comment is implying that legalizing or decriminalizing csam would somehow help with prosecution of child abuse? I’m kind of speechless. Csam IS child abuse. The fact that there are consumers encourages producers to, well, produce!

IncreasePosts10 minutes ago

There's also the argument that CSAM can act as a gateway leading people from just being a pedophile in their head, to going out and doing something to some child.

goalieca25 minutes ago

Our society is pretty aligned that distribution is another kind of harm. Non-consented distribution of sexual images (eg: revenge porn) is also a crime. Children don’t need to be the ones to press charges in child porn unlike with adults. That’s a good thing.

ux26647817 minutes ago

> Our society is pretty aligned that distribution is another kind of harm.

As well as possession. I don't actually know if those are different for CSAM, but I would assume so because they are for drugs.

IMO "end-to-end encryption" simply isn't possible when the application is run by the same company as the servers the data sits on, is closed source, and can at any time, see the decrypted contents of data it downloads from their servers and do whatever they want with it.

Same issue with Proton, MEGA, and any other e2ee app... it's only useful when the company decides not to mess with the data it could always decrypt locally. Also why people are hesitant to use javascript-based e2ee solutions where the site owner can modify the code at will to do what they want.

SepiaSapient29 minutes ago

Beyond the privacy marketing angle, e2e allows companies with global exposure to sidestep any unpleasantness when they get a subpoena from Bumfuck, Nowhere.

Sure, the NSA, GCHQ and Mossad have a way to get the encrypted data by a sidechannel but proprietary e2e is a good thing for most people IMO. Shifts the risk from "my messages are theoretically available to most law enforcement in the globe" to "YOU’RE STILL GONNA BE MOSSAD’ED UPON"[0]. This is specially good for me because I know the equivalent to the FBI where is live is too cheap to buy a Cellebrite [1] license.

EDIT: I suppose someone could ask about Meta. The reason behind their support for scanning (and removing e2e in facebook msg) is simply regulatory capture. The zucc wishes to have a letter of marque to "protect" your children and remove the "unsafe" competitors.

kyralis48 minutes ago

This is based on a faulty understanding of the underlying systems. The risk with this sort of E2E encryption is not that the service provider pinky promises not to decrypt what they have, it's that they promise they will not insert a new key into your circle of trust to subsequently start decrypting things.

slashdave44 minutes ago

Only if the company misleads and adds a backdoor to the front-end app (thus this entire discussion).

If the company is misleading, any encryption technology is irrelevant anyway.

The judge called the outcome disturbing, as it leaves victimized children as "collateral damage" of privacy protections.

As sad as this is, end to end encryption means no CSAM scanning.

As an alternative Apple previously tried to do scanning on the phones locally but caught hell for that too.

This is one of those unfortunate tradeoffs but I see no alternative to privacy taking priority.

0cf8612b2e1e47 minutes ago

People can also distribute heinous things through snail mail, but we are not yet at the point where the government reads all letters looking for wrongthink.

Just because we technically can make a privacy destroying drag net does not mean we should. Had phones existed 250 years ago, I have no doubt the founders would have thought it obvious that a cellphone’s contents were your personal papers which could not be freely searched.

timcambrant12 minutes ago

But that's mostly because it's impractical. They do use dogs to sniff for drugs and explosives, so if CSAM smelled or was visible through X-ray then it would probably be a different story. And let's not forget snail mail is by far a more uncommon way to spread that material than the Internet is. The Internet came into broad use just ~15 years after commercial CSAM was openly being sold by mail order in Europe.

Personally, I am on the side of privacy, by the way.

ajsnigrutin38 minutes ago

More effort should be done to find real-world equivalents of such actions and "think of the children".

An icloud is like a storage locker or a safety deposit box... the owner should go through all your stuff there, just in case you have some CSAM!

Metadata is just tracking info about who, where and with whom... every bartender should take your IDs and log when you came to the bar, who you sat with and how long you talked there.

EU Chat control is like general eavesdropping... every time you sit down and talk with someone, an EU bureaucrat should sit next to you and listen and write down your conversations, just in case.

etc.

Somehow people think that "it's ok if it's on the internet", even when it's stuff they'd never accept in real life.

Children are often used as a weapon to erode freedoms, like privacy and speech. Those pushing it rarely actually care about the children.

While I’m decidedly pro-encryption, I don’t like this argument. If something is the right thing, it would still be the right thing when promoted for the wrong reasons, and if it’s the wrong thing, it’s still the wrong thing even when at present nobody has ulterior motives.

When arguing against surveillance, the arguments should be on its merits, not on whether the current proponents happen to have ulterior motives.

ajsnigrutin33 minutes ago

So invading the privacy of millions of people, even if it's just automatic scans for some specific thing is a right thing? Does this apply to mandatory drug tests for everyone everywhere? How about drug and weapon seeking drones, doing daily checks in every apartment everywhere? How about mandatory AI powered microphones everywhere that would detect threats, blackmail, any talk about anything illegal, etc.?

If you take a 1000 random people of the street now,how many of them are sharing CSAM via icloud?

If you take a 1000 random politicians, how many of them have corruption scandals? Why not start with them instead, a bodycam and an AI powered microphone that would detect corruption automatically... let them lead as an example, before they apply the laws onto "the rest of us".

layer832 minutes ago

You misread what I wrote. My comment is against the argument used, not against what is being argued for. Using the wrong argument diminishes one’s position. I’d prefer the stance against surveillance to not be diminished by such arguments.

Not true. There is the option of scanning on the device.

I wonder if the judge would be in favor of companies proactively going into people's houses at random to check on their belongings, if they don't have inappropriate photos somewhere, or whatever.

It's harder to do, but conceptually the same. So sad it's not being done. Very disturbing.

They could do it when people are not at home. There'd no problem, nobody would even notice.

Kind of a bad analogy (not service related, no associated liability).

I think it depends on your definition of e2ee and where the "end"s are.

If the locally running application can decrypt the data, it could always do whatever it wanted. Is that really how you define e2ee?

The locally running application is one of the 'ends' of the end to end encryption.

Then in that case I think the previous statement of "end to end encryption means no CSAM scanning" would be false.

I simply don't trust services such as iCloud. The legal landscape is too volatile, and Apple's own "terms and conditions" are also subject to constant change. As far as I can tell, most people don't need cloud backups, and iCloud mostly shows up as an annoyance designed to extract more money from customers. In fact, most people probably don't know that Apple and Google vacuum up their files the moment they are created, for their own good, of course.

Ah, the CSAM saga. Very poorly handled by Apple. Suspect it may have taken Hair Force One off the shortlist of CEO succession.

St0n3d59 minutes ago

“Apple created its own proprietary alternative, NeuralHash, which apparently wasn’t as good. So Apple U-turned on its efforts to scan for CSAM in its cloud storage. Instead, Apple implemented end-to-end encryption for iCloud files.”

Wasn’t Apple’s design to explicitly NOT scan in its cloud storage, but look at the file on-device at the moment you wish to upload it to iCloud? This method would make it compatible with Advanced Data Protection; so ADP could have always been in the pipeline rather than Apple u-turning. In fact, NeuralHash may have been proposed because Apple wanted to introduce ADP and saw a potential problem here/get concerns from government agencies about it and saw this as a means to an end(-to-end).

The system was designed pretty elegantly and offers far better privacy protections - including guardrails - than what Microsoft and Google do, but the communication from Apple about it was absolutely horrible and generated enormous backlash. (Not saying I agreed with implementing it, just saying the design was infinitely better than competitors.)

Also, Apple's E2E iCloud encryption vastly predated the NeuralHash efforts.

Seems like the kids miss their chance at justice because of section 230 allowing platforms the freedom to remove whatever they want but not be responsible for what they keep or amplify. That is the problem with 230. Censorship is permitted and punishing the censor isn't. Twitter and Tiktok are literally microblog platforms that get away with removing good stuff and leaving evil because they "are not a publisher" while the algorithm literally publishes a chosen set of articles to people. Facebook can remove religious freedom material and leave human trafficking groups. Section 230 gives the publishers the cake and the edict too.

I know creating a throwaway to hide your name for an opinion is a bad manner, but this one is one I really don’t want linked back to me

The VAST majority of “CSAM” is consensually created and exchanged by teens. Their future selves and their parents form this pressure group attacking everyone’s liberty and privacy to try to undo the downsides of choices they made themselves with full knowledge of what could happen.

The criminal and disgusting tail end of this type of material deserves the worst of consequences for the perpetrators and all the support in the world for the victims, but these are mostly - you guessed it - poor and unprivileged children from far away places and they certainly can’t put this much pressure on apple

kstrauser57 minutes ago

I think you’re right, but from another angle. In the state where I lived way back when, a state representative put forth a bill to explicitly make e-CSAM illegal. I guess it was already illegal for print media and this covered a gap in the law about cell phone pics, etc. Thing is, it had no allowance for the age of the picture taker, or even whether the picture taker was the photo subject. If a 16 year old girl took a nude selfie and sent it to her boyfriend, she was a felon.

I wrote to the rep and explained my concerns. I wholeheartedly agreed with the intent of the law, but the code was buggy. To my surprise, he wrote back in horror to say he hadn’t considered that and pulled the bill immediately. I’m proud of having done that.

I’m 100% pro yeeting child pornographers into the sun. I still don’t want to throw kids in prison or remove all traces of a right to privacy in our haste to sun-yeet them.

aljgz1 hour ago

Are there statistics backing up the "VAST" majority claim?

While on statistics, I wonder, are there reliable statistics about child abuse of different types? Studying correlations with other social metrics, like sex education, liberal/conservative, policies regarding prostitution, and others can provide support for/against decisions.

Not that I hope these will impact people's and governments' choices, but I want to challenge my intuitions.

I'd say modern AI tools could probably do this pretty effectively. They're very effective at describing anything else about an image.

Our legal systems are not built to deal with that mess, and it may hang around your neck for the rest of your life.

dfxm1240 minutes ago

I won't pretend to be so knowledgeable about how so much CSAM is being created, but keep in mind, there are laws against distribution & mere possession, too. Revenge porn is an obvious thing to be mindful of in this context in addition to other types of distribution. Consent to create doesn't imply consent to distribute (probably even to cloud storage) & is completely immaterial to issues of possession if it ends up in some 3rd party's hands. So the scope goes way wider than you're letting on. If you're saying all of these these laws are being abused, like they exist primarily to punish a state senator's daughter's ex-boyfriend, I would ask for something to back that up.

Yes, poor and unprivileged children can't really defend themselves here, but this is the system working to find some legal mechanism to do what it can, as a more powerful force. Protecting people from exploitation is a good use of government. If this was shot down for legal reasons, OK, the system is working and I hope there is a way to expand protections that fits into our system.
