> Modern cameras rely on sophisticated image-processing algorithms to produce the final viewable image, so certifying that an image accurately reflects what a real camera sensor captured requires a chain of trust covering the sensor as well as the computational photography software that interpreted the capture. So if you jailbreak or root your phone what happens? Is this a trojan horse into making rooted phone camera…

Presumably you would only do this for images you plan on sharing to social media anyways, to prove that it's not AI generated. PCC is quite good, about as close to private remote compute we can get without doing HME.
If homomorphic encryption is not involved, how does Apple not have access to the raw image data being sent to PCC? (Genuine question)
> or via software-level jailbreak of the device. I’m surprised that even Apple calls jailbreaking, jailbreaking. Doesn’t that imply their own software is a jail?
This is really clever from Apple. The journalist use case is just the PR story. This will be really useful for identity verification and insurance apps, and has the potential to shift from "you need a smartphone to be able to live normally" to "you need an iPhone to be able to live normally". There are already plenty of insurances that require you to submit claims through a smartphone app that tries to essentially do…

You have it all wrong. Apple Reference Image is not an id system; it's primarily a way to attest that the pixels recorded by…
EMPs are not "alien technology", and you don't need to be a nation state either. That said, Apple's hardware security is generally very good.
Yup, you don’t even need nukes: https://en.wikipedia.org/wiki/Explosively_pumped_flux_compre...

I mean, the obvious one is that they can revoke certification of a photo despite it being real. The harder one is they can force apple to certify a fake photo. the part that would be very hard but not outside the realm of plausibility, is that gov could force apple to introduce a bug in its pcc platform to link photos to the photographer in order to track and arrest inconvenient people. Apple says there are a bunch o…
> This entire system relies on trusting apple It does indeed, and that is a fundamental flaw. but as has been discussed here, it is better than the alternative, which is no verification. During the pandemic, I outlined a scheme for using blockchain technology for image provenance and authenticity tracking. The idea was that instead of any one entity assigning authenticity that it would be done in a crowdsourced manne…

Doesn't OIS increase the size of a sensor by roughly half and thus take some significant engineering and design cost to accommodate? At least it seems that way in the phones I've taken apart and looked at. Also, OIS is a major mechanical add on (a literal motor) and even 1500usd smartphones lack it on some of their sensors, mainly because while it can have an advantage on an ultrawide, that tends to be more limited.…
> Doesn't OIS increase the size of a sensor by roughly half No, you can apply smartphone OIS-tech on any sensor, stabilization is achieved via the lens-array, not the sensor. The size of the module slightly increases but that's not a hindering factor. Cost/Benefit of OIS on ultra-wide lenses is not there, so it's usually not applied. > Your logic would lead to OEMs making SOCs without things like TEE and other things…
And despite that experience, you do not see the universal value in reliable, verifiable image attestation for any user? You cannot imagine why that may not just be very useful, but quickly become required, what the "end-user demand", "business-value" or "industry-requirements" could be?

It’s possible for Apple, as stated in the blog post (e.g. “which lets the device later produce signatures that Apple can attribute to that specific phone”).

At least for the image itself, using direct projection onto the sensor (in a way similar to a retinal projector or film recorder) would be difficult to detect I imagine?
EU wants Apple to implement digital fingerprinting to fight CSAM: overreach of power, total invigilation, nonono! Apple cannot comply! What about our privacy!
Apple implements the feature and sells it nicely wrapped in a PR material: oh, that's cool, innovative!
