Shouldn’t it be impossible for them to even be able to hand over your notifications in the first damn place.
There’s no reason I can think off that they should even have this info.
it’s up to individual app developers to encrypt the data in their push notifications. as for the data about the notifications (the metadata stored on Apple’s/Google’s servers), that could end up being potentially useless if it were just a block of timestamped and encrypted data sitting on Apple’s or Google’s servers. Presently, that data often also includes the full notification contents, unencrypted.
But when those companies get a court order/subpoena, they have no choice but to cooperate.
edit: for clarity
The metadata is actually quite important.
Sure, chances are it’s a “pending WhatsApp message” notification, but not the actual contents of the message.
However, with enough metadata and by surveying traffic from WhatsApp data centers, someone could see User A accessed WhatsApps service, which generated a WhatsApp notification for User B.
That might just be a coincidence, but with enough data and time, the probability that User A is talking to User B can be increased.
If it also shows that Users C, D and E also get notifications at the same time, it is likely that all those users are in a group chat together.
It’s called a timing attack.
And perhaps it isn’t enough evidence to stand up in court, it can help build the profile of the users, and guide investigations to other possible accomplices.I realize that sometimes metadata can be aggregated in nefarious ways. sometimes, however, it’s useless. currently, however, it contains all of the unencrypted contents of the notification itself, not just the metadata, and my point is that’s it’s better to take the step of encrypting the notifications themselves to at least protect that data.
But why would a copy of the notification history exist outside of the phone itself? I can’t think of a reason why notifications should be collected at all.
Imagine you have 20 apps that can send receive notifications from remote (messaging apps, offers, updates…). That would require each app to be active in the background and pulling updates. That’s a massive battery drain.
Instead, the apps send the notifications to Apple/Google, and the OS checks for all of the apps. The apps don’t need to be awake (the OS could show the notification or wake the app) and there’s only one service checking for the ml notifications.
It’s a massive oversimplifying and probably I made some mistakes, but that’s my understanding. Hopefully somebody can correct me.
Apparently that’s how it works.
I’d imagine a notification service on the phone that can receive or pull from all the various sources on behalf of the apps installed. That way the app servers don’t need to hand the data to Apple/Google servers. It just seems like an extra step.
On Apple, there’s only one notification service. All notifications get pushed through https://en.m.wikipedia.org/wiki/Apple_Push_Notification_service which go through Apple’s servers
By doing it that way, you are all the sudden generating tens, if not hundreds of requests per minute to grab notifications for every platform and service, rather than just the one. With a unified approach, the phone can wake up in the background every 5 minutes and ping Google to ask for notifications. If everyone did it individually, your phone would never be able to go to sleep, and would CONSTANTLY be sending out requests to random servers. That also brings up security concerns, since you can get a vague idea of location data from a request, any app that can send notifs can soft track users. They would also open the door for one to be compromised, and send malicious info much easier than it would be to do thru Google. All around, its just a worse solution to the problem with one very small benefit.
Well, the problem is that every would need to have their own server with notifications waiting to be pulled (imagine your phone goes offline) and they need to be beefy enough to answer potentially thousands of requests per second. Almost impossible for small devs.
There’s also additional battery need, as it’s many calls and payloads, and if a server is slow it can affect all the other notifications. Plus more area of attack.
Not impossible, but I don’t think it’s the direction things will go.
there’s a lot of different reasons why it might exist, depending on how the app or service work. some might have no data history, some might have a lot with a long footprint. some apps/services may benefit from rethinking how their app/services handles/routes this data.
it’s complicated.
That makes some sense for an individual app collecting its own history.
Apple or Google collecting all notifications seems like data collection for its own sake, with no real useful purpose.
oh, I se the misunderstanding— you’re confusing simple on-device app notifications with notifications using the Push service, which actually requires being sent through Apple’s or Google’s servers and may originate outside or your device from a service on a 3rd-party server.
Oh! I didn’t realize they actually went through Google or Apple servers. Not sure why that’s a necessary step, but at least it explains why they would have the data at all.
Thanks
Yeah, not all notifications originate from apps on your device. If, say, Amazon, updates, your delivery status, a push notification gets sent to your Amazon app from Amazon, then you get a notification on your device. That push notification goes through either googles servers or apples servers before it gets to you, that way, they know what device to send it to. That device ID is registered the app on your device with either Apple or Google on their servers. 
would end up being mostly useless if it were just a block of timestamped and encrypted data sitting on Apple’s or Google’s servers
If you are only interested in the data, sure.
But metadata is also very powerful, specially when aggregatedBut metadata is also very powerful, specially when aggregated
it can be, depending on the context and what metadata you get. it can also be useless or of very limited value, even in aggregate. it’s really a roll of the dice, depending on the case. while I agree that no data access would be preferable to a little, my point is that encrypting the notification contents (a step which app devs can and should take) provides far better protection than what the cops get now, which is all.
The article is incorrect in equating Apple’s stance to Google’s. As far as I can tell Google does not require a warrant, only a subpoena (which doesn’t require a judge’s review), while Apple’s change does require a court order or a warrant, both of which require a judge to sign off.

Requests from US government agencies in civil, administrative, and criminal cases
The Fourth Amendment to the US Constitution and the Electronic Communications Privacy Act (ECPA) restrict the government’s ability to force a provider to disclose user information. US authorities must at least do the following:
In all cases: Issue a subpoena to compel disclosure of basic subscriber registration information and certain IP addresses
In criminal cases Get a court order to compel disclosure of non-content records, such as the To, From, CC, BCC, and Timestamp fields in emails Get a search warrant to compel disclosure of the content of communications, such as email messages, documents, and photos

Thank you for the facts.
A good step, but seems like spilled milk after the previous news.

IMHO, they have much more to lose if they decide to start getting shady around privacy and security stuff in western nations. They’ve sunk too much money into building a brand around privacy and security.

I mean, of course, yeah. By mainstream I mean what your average consumer would purchase and use. They almost certainly will not be rooting a device
I am the family tech support and I certainly will not be rooting a device.
And I would almost certainly recommend Apple to my family for the “mainstream privacy”
Nobody would define that as mainstream.

Rooted, degoogled AOSP is definitively not “mainstream”. Mainstream to me means something you can but off the shelf and start using without having to modify it.
Are you kidding man? The options are things you can buy off the shelf and turn on.
If you are rooting, configuring etc you are off the mainstream

Well, we know they’re not, but the people that eat up all the ads Apple makes about their shallow privacy features you have to manually turn on don’t.
How do people read giz? I block the ads, but still there’s a sticky video overlay, and “related” links everywhere… unreadable
I’m using pihole for DNS and ublock for Firefox on android and I get no adverts.
Saaaame and the stupid video still follows me.
Lotta white space.
I can see why these web sites are dying.
Gawker media was sued into the ground by a billionaire quite a few years back for posting an article about him being gay and now it just exists to make as much money from adverts as possible until it dies.
It used to be quite a good group of sites for tech news and such.
Gawker was godawful and deserved to be killed. They had a service called (not kidding) gawker stalker which gave live updates on celebrities locations, an actual stalkers wet dream
Would it be possible for Apple to just encrypt this data or, not keep this data? Then there would be nothing to give law enforcement or government. (Forgive my ignorance, I have no idea how all this works.)
The developer of the app sends the push notification through Apple’s service. Developers have always been able to encrypt it, at which point it can be decrypted only by their app, but not all developers do this. There’s also still limited metadata about the fact that a notification was sent, even if the contents are encrypted.
Would it not make more sense to remove metadata and not even collect it? Maybe have an encrypted protocol for push notifications all developers use regardless of the app?
Your phone has to be informed somehow, from the internet, that it has data to present as a notification. The fact that you got a notification at 3:32 and then again at 3:35 is trackable data, pretty much no matter what anyone does with it, encrypted or not. Doubly so if someone has MITM attacked your data stream. They may not know what the notification contains or even what app it was sent to, but the act of transmitting and then receiving this data packet over cell network or internet is a trackable event. And I don’t really know what Apple could even do about that beyond attempting to build Internet 2 solely for the purposes of keeping the cops out of it, which is unlikely at best.
Honestly I think developers should just use push notifications to tell the app to directly fetch the notification contents from their server, rather than sending the contents of the notification using push, where it is stored by Apple/Google.
Or do what Element and Syncthing do, which is bypass that entire Google push infrastructure (FCM, formerly GCM?) and connect directly to their own ones instead - at the expense of some additional battery consumption, particularly when there’s poor cell service. Due to iOS restrictions on background apps, this probably isn’t possible on that platform?

Why not chuck the data when it’s no longer being used, though?
They do. Apple is sending literally trillions of push notifications per year and certainly doesn’t want to save them longer than necessary (a useless expense), but the government can also ask that information for a targeted user be retained, going forward from the request, even though it would normally be purged.
Because protecting user privacy is not a priority.
It’s possible that they could encrypt and anonymize this data with yet another set of tokenization, but that would be quite an effort on their part. As for not keeping the data, the metadata, itself, it’s necessary in order to coordinate the sending and delivery of push notifications between apps, services, and your devices. It needs to exist.
This is the best summary I could come up with:
Senator Ron Wyden wrote a letter to the Department of Justice last week accusing foreign governments of spying on Americans through push notification data.
Senator Wyden says Apple was “doing the right thing by matching Google and requiring a court order to hand over push notification-related data,” in a statement to Reuters Tuesday.
This metadata flows through Google and Apple’s servers and could be used by law enforcement to expose the true identities of anonymous online users.
If a government wants information to associate an APN token with your Apple ID, those “records may be obtained with an order under 18 USC 3703(d) or a search warrant.” Both of these provisions require a judge’s consent to hand over this data but call into question how easy it was for law enforcement to access it in the past.
As Wyden calls out in his statement today, Apple’s update matches Google’s language in its Privacy and Terms, which also requires a subpoena or court order to hand over metadata about users.
Google was the first to publish a transparency report detailing how many government requests the company receives for disclosing user information.

I have zero Google services on my phone only microG. Does police still have access to my push notifications if they ask for it?
It’s not the services, it’s the push notification itself. It’s like a book, where the push notification is the cover, and the app is the pages. The government can’t open the book, but they are able to look at the cover all they want.
This is apples move towards putting a cover on top of the books cover… kinda. The metaphor breaks down when you get into what Apple is doing here to be honest.
Your move googs
Read the article. Google already requires a warrant before handing out this data.
Google only requires a subpoena.
That’s the problem, I don’t want Google to have my messages. It should in fact be in my phone.
So don’t use cloud backups. Same with iOS. If you want it local, keep it local. No one is forcing you to host your data in someone’s cloud.

Google doesn’t require a warrant, Apple does.
Since google wasn’t requiring a court order before this (like Apple), I’m not sure how this makes them better. From this statement, both Google and Apple will be moving forward with a legal requirement to access this metadata in the future. They seem to be doing this together.
it seems they were both caught giving up data without a court order before and are now both doing the right thing.
