*Anything* in image form.
Got it…and that’s what I thought (and others have “implied”

)
Next question, how does THIS, now, stop them or ever stopped them from ever doing this before or in the future? Where was the outrage when Apple added hashed comparisons years ago?
Some will argue that those were for the user benefit and not “policing” us, BUT you specifically state you are worried about someone (government or other entity) MAKING Apple look for other “stuff”.
They could ALWAYS have done that (hell, maybe they are already doing that or have done it).
What about this specific way of comparing picture hashes so that ONLY those pics or tagged if being uploaded to iCloud has everyone so up in arms when this is already being done?
They could “tag” ANY pics they want to today without you knowing. No one disagrees with that. The question from me is why are people so concerned now and not with the fact that they have had this capability for years? They CAN scan every pic one uploads to iCloud to look for ANYTHING (you have actually give them that right by using iCloud).
They CAN put it in iOS to scan for ANYTHING on your device if they wanted to…yes, illegally in most countries, but they COULD.
The disagreement here seems to be that their efforts here are to NOT scan photos in iCloud. To NOT compare ANY pics on your device if you do not have iCloud sharing turned on (you don’t have to believe it, but until it is proven to the contrary, I choose to believe what they are saying). To only “compare” hashed database images and mark them so that IF AND WHEN they are uploaded to iCloud, Apple could know about that once it is already in iCloud and NOT every single image you might upload.
I’ve said it before, I can’t make anyone believe what Apple is saying is true, but this specific addition to iOS doesn’t change anything else in my opinion as to what they are saying or breaks any laws (particularly in the US).
If Apple chooses to drop this “on-device” method of marking photos that are being upload to iCloud, they will just actually scan every single photo in iCloud. The outcome will be the same, but now they will have be accessing every single thing I upload to iCloud, or for the conspiracy theorists out there, giving “someone” the ability to alter that scan to “see” anything they want. Versus Apple’s way which at least has them with a much tighter toll gate with iOS versus iCloud.
iCloud - Easy to break into with a password for any hacker to view or even upload images as well as access a ton of other data. They can do that today.
Hard coded on iOS - Unless using a super advanced Trojan horse link that you accidentally click on opening the door or someone within Apple accessing the data, hackers have extremely limited capability to get into your phone unless they actually have it as well as access to unlock it.
I prefer the on phone comparison method for my own protection. Doesn’t make iCloud anymore secure, but adding this type of ”check” to iCloud is much more open to abuse by anyone than on phone analysis.
