Apple plans to scan US iPhones for child abuse imagery
Apple intends to install software on American iPhones to scan for child abuse imagery, according to people briefed on its plans, raising alarm among security researchers who warn that it could open the door to surveillance of millions of people’s personal devices.
Apple detailed its proposed system — known as “neuralMatch” — to some US academics earlier this week, according to two security researchers briefed on the virtual meeting. The plans could be publicised more widely as soon as this week, they said.
The automated system would proactively alert a team of human reviewers if it believes illegal imagery is detected, who would then contact law enforcement if the material can be verified. The scheme will initially roll out only in the US.
Apple declined to comment.
Has Apple spoken more to this yet? I have yet to see anyone in our industry offer up rationale for why this company that fought so hard to deny the FBI access to a terrorist's iPhone is no proactively developing surveillance functionality into the device in this way. I think we can all agree that preventing child predators is a good thing, but not like this.
With a few days to digest this and gather info/opinions, what are your thoughts?

I was completely unaware of this, but I still think Apple's take on this is way more invasive than Google's. According to the link you provided, it seems that Google scans images sent/recieved through Gmail, which technically means that they're not actively scanning people's devices. Apple wants to proactively scan your gallery.
While I agree that their intentions seem to be good, how are they gonna rule out 'false-positives', like a picture taken on a hot day at the beach? And even "worse" - how can I be sure that they won't scan more stuff from my phone without my consent? Whilist I don't have anything to hide, I rather keep my stuff private.
It's not quite like that - they're not actively "scanning" and then using AI or whatever, instead they simply calculate a file hash (checksum) and comparing that to a database with hashes of known (confirmed) CP imagery ... that's probably about the most robust and least questionable way of implementing this kind of thing.
Hey, thanks for the answer! So this means they won't get the images, just the hashes, right? Any place I can read more about how it'll work? I'm really interested on understanding more.
Yup it's here in their FAQ, it's very clearly explained here how it works:
apple.com/child-safety/pdf/Expande...
What they do is download a little database (list) of those hashes to your iPhone (this list gets updated regularly), then when uploading a file to iCloud they simply compute the hash/checksum and compare it to the list.
Apple had been positioning itself so distinctly against where Google stood on all of this stuff. This was your option if you weren't in favor of all the Google stuff.
There's even a universe where Apple outlines specifically how and why this needs to work in this specific way and offers up an explicit answer to dissuade any slippery slope concerns, but it just doesn't seem that way.
John Gruber has some good analysis on this: daringfireball.net/2021/08/apple_c...
I'm very concerned.
Of course they said a lot of things to reassure people, like:
I must notice that this system is only going to catch dumb criminals, who may well opt for other, more private ways to exchange their stuff. So I'm unsure if this will do any good... But if it catches one, is all good, right?
Well, not really. The point is: we must rely on Apple's good will to keep things like that. They can remove any of the above limitations at any moment. The tool can potentially scan anything on the phone.
And I can give Apple the benefit of the doubt, so I'm sure they don't want to steer away from their intentions, but what if they are forced to do so? Are they just going to say "no"?
What if country A tells Apple: "Enable your scanning thing here and use this database of hashes instead, or else pay this huge fine and/or be booted from our market"? Easy abuse of a system born with good intentions.
Remember how China has been oppressing the Uyghurs in the Xinjiang region? They install a scanning malware in their phones.
So it's not just a slippery slope, it's a shaky step covered in grease.
Now I'll explain the worst case scenario: Apple developed this technology because they've actually been asked to. And we'll probably never know the commissioners, even if we can have our suspects.
The system might actually be active outside the US, for what we know. Or the US version could be a large scale test, prior to a world wide release.
All this leads me to think that if a company that used to shout "what's in your phone, stays in your phone" proudly, ends up dismissing all the controversy as "screeching minority", it's pretty clear that they don't value privacy because they love human rights, but because it's just a flag to wave exclusively for marketing purposes.
We don't need this.
Fuck privacy! This is great. Is for a great cause.
Are you serious, or is this irony? Many things that have been said to be "for a great cause" have turned out disastrous.
Most people that think like yourself live in a bubble. A bubble with a seed that someone else planted. I could care less about your privacy. Nothing in life is perfect. Is all about supporting the lesser evil.
Besides, if you have nothing to hide you have nothing to worry about.
You're assuming a lot, aren't you? First of all, "most people that think like yourself ..." - so, you pretend to know exactly what or how I think? Maybe you're clairvoyant, it can't be based on my comment (and I didn't even mention privacy).
Another nice one, "A seed that someone else planted", oh yeah, give me break LOL ... yes sure, I'm totally brainwashed, I can't think for myself, unless someone else "plants the seed". But you are such a critical and independent thinker, right? So the "if you have nothing to hide" argument is your original thought, but how come then I've heard that one so many times, sounds like a cliche and a classic fallacy of there ever was one.
And then to top it off a nice putdown like "I could care less about your privacy", oh such a nice, friendly and polite way to discuss things, yes we really need this level of discourse here on dev.to !
Who needs privacy? Privacy is overrated.
"Activist X is an enemy of the state, please check their phone". Said every corrupt head of state ever who jailed people labelled as dissidents (super recent example: the president of Belarus jailing activists and even sports athletes)
If you think privacy is useless because you are a good citizen and you never committed a crime, then you don't really know what privacy is for :)

Funny how apple calls it ‘ Expanded Protections for Children’ yet they use children to assemble their phones.
I also wonder why Apple has taken this step, at this moment. Maybe some gentle urging from the direction of US authorities or government?
I can't help but notice how companies like Google, Apple and so on have all these lofty and pompous ideals and principles, only to drop those the moment they think they need to please the authorities.
Ah really? yes well that is in fact quite lenient ... I agree with you on all counts, also about the media coverage. Never good to jump to conclusions too fast, and vilify a company or an individual before knowing all the facts.
Thanks a lot for this. I'm gonna read it entirely, because just the first page got me even more interested - the idea of matching known hashes on-device is incredible and now that I learnt a bit more about it I'm not as concerned about privacy as I was yesterday.
Yes I agree that this seems a clean approach - if they'd do shady things like unleashing AI algorithms on images to start guessing "what it is" and then framing people based on that, well that would definitely be a big no-no. This thing with the hashes though seems about the cleanest approach you could come up with.
I liked Dr. Neal Krawetz's take on this issue.

Not sure why apple is doing this or rather why apple chose to disclose it now. It's very odd.
Based on the headlines I was ready to be upset with Apple. But everything is clickbait nowadays. After reading more of the details I don't have as much of a problem with it.
I am concerned what doors this opens in the future for privacy invasion. However I think the only comprehensive way to address this concern is with laws which guard digital privacy. Otherwise policy is up to each company's leadership. And even if I believed they were doing things the "right" way for privacy now, leadership eventually changes.
I tend to agree, I've read Apple's FAQ and their approach does look focused and targeted, it's not a broad sweep big brother kind of privacy invasion thing (there's also no automatic reporting to law enforcement, which would arguably be a bridge too far).
I'd even go farther than this, I'd be fine for them to filter/flag other horrible stuff (domestic violence, animal abuse, whatever) with this hash technology if they've got reliable databases of those - but their response should be a warning to the user trying to upload that and tell them stop doing it or risk termination of their iCloud service.
And of course state all of this clearly in their user agreements.
More than happy with ways for them to stop horrible stuff being stored on their cloud (well yeah, it's their cloud alright).
Hold on, can you substantiate the claim that Google's apps are spyware, or are they rather just collecting anonymous usage data for the benefit of their advertisement business? IMO you can't just equate those two ...
In my mind companies like Apple and Microsoft with their obscene profit margins are just as "evil" (if not more) than Google - their business model is just different, which allows those two to act sanctimoniously versus Apple and Google when it comes to privacy (but Apple and MS are detestable in other ways).
Yeah maybe we should blame ourselves, but OTOH maybe most of use don't care that much ... and even if everything's open source, someone's gotta pay for hosting and running the services, or would we all suddenly go take a subscription instead of enjoying freebees? If you give people a choice then most of them will take the freebees with ads rather than a subscription.
Ben, is the statement that "Apple intends to install software on American iPhones" factually correct - is Apple planning to install software on US iPhones, or will they put systems in place to scan images stored in the iCloud by American users? Big difference if you ask me (although even then it's still a form of surveillance and "big brother").
What irks me most is that they would then go on to scan for stuff like child porn and such but not other vile imagery like domestic abuse, animal abuse and I could go on. Why take measures against one form of abuse but not the other, is there some sort of agreed-upon hierarchy of evilness or whatever? It reeks of hypocrisy and it's a slippery slope, that's why companies should refrain from this.
Yes, they are going to install software on the phones. The FAQ Apple put out as well as the rest of the released documentation is very clear that all scanning will be done on-device. See the FAQ PDF for details.
The answer to your second paragraph. On one side, Apple have hashes for CP images that already exist and both the acts depicted and the images themselves are illegal. On the other side, while the acts of domestic and animal abuse are illegal, images of those acts generally aren't illegal to posses. The supposed purpose of Apples program is to combat possession of illegal CP images, not to stop the perpetration of illegal actions, so nothing hypocritical about that aspect of it.
I do agree it's a slipper slope that no company should go down.
Thanks for clarifying, sound reasoning ... possessing those images is indeed illegal, so I think they have a pretty strong case in saying, we just don't want this stuff in our cloud, ergo we need to block it ... because well, Apple could even be held liable for storing it on their servers, and being complicit in a crime.
And with the hashing technology they arguably have the least questionable approach that you can think of. So yeah slippery slope, still, but there is something to be said for this.
(if they'd not just block it but also report perpetrators to law enforcement then I'd say "bridge too far", but that's not the case, apparently)
