they must also be using some device identifier that is preshared with the various trusted devices, otherwise each device would broadcast the same public keys on the same interval.

Obviously if everyone's devices were all broadcasting the same public keys at the same time it would be stupidly easy for apple to deanonymize the data.

in the future, 90% of bluetooth bandwidth will be apple devices endlessly confirming their own location to each other

mystes posted:Maybe "contains the same private key" just meant that all of your devices have copies of all of your other devices private keys, not that they all share the same private key? yeah that makes sense

Also I was half joking about making cheap third party devices that would take advantage of this system, but based on the way it works they could probably easily allow you to find small bluetooth-only devices like airpods with it or even launch their own tile clones to allow people to buy tags for their keys or whatever. It would actually work a lot better then tile because every iphone in the world would be looking for your keys, rather than just people running the tile app.

Also incentivizes Apple to make their products even more expensive. If you lose your gadget it doesn't need to be an immediate sunk cost. And maybe avoid being hassled by the US govt. CmdrRiker fucked around with this message at 22:53 on Jun 6, 2019 |

yeah it would be increased battery and data usage on every device and then a shitload of storage on apples side. another thought is that the reporting time period would need to be randomized somewhat. if its the same for everyone then your servers need to handle bursts of data. if its spread out and not randomized, them maybe you could identify someone by their beacon interval.

Would those other devices need a way to locate themselves or can they just act as beacons and broadcast themselves to other GPS enabled iPhones?

mystes posted:The description posted earlier made it sound like other phones would add the location (encrypted by the public key) so if that's correct the devices being located wouldn't need a way to locate themselves. could probably use less it by doing less if you see more iPhones nearby and not broadcasting if you’ve been unlocked recently, or are talking to a currently-worn watch

if someone steals ur phone and figures out your super secure password of 000000 you probably don't want it to stop broadcasting

Sam's Club theoretically has one that works like that (which seemed like a brilliant idea) but it wouldn't let me check out the one time I tried it yeah they have you add a credit card to save with the store and pay from there,though you can also just scan through the app and then put in your card physically at a pos at the checkout area

You can monitor that other iOS devices in your proximity are beaconing, but the ids are encrypted and rotate so you’re probably not going to get much out of it the same way that they beacon forged MAC addresses when polling for wifi

Volmarias posted:It also doesn't address the issue with getting anyone in a position of authority to reclaim your device to give a poo poo about it. also my first thought old: serve a production order on apple to compel them to tell me where your device was last week, which isn't enough to form grounds to believe that's where your device is right now new: look at your screen and listen to a story about unverifiable information only you have, and take it on faith that the thing i'm seeing on your screen is really real, which roughly 0% of patrolmen are going to do and about that same number of detectives are going to have time for if apple were serious about it, there'd be a law-enforcement-only version called "find that guy's iphone" but just loving lol out loud at any sensible person ever agreeing to give the police a means to track them

I bet it takes up less space than whatever fraction of their web logs they hold.

We bought some of those canaries from Thinkst and they have bluetooth functionality. Unfortunately it's only used for setup because it'd be kinda cool to have btle honeypots

Is there anything to stop large scale aggregate pulling of all points? Wondering if you could pull a bunch and aggregate where people go in military installations or whatever like people did with fitness trackers.

The devices transmitting the data are cellphones which are being located all the time anyway even without this new system.
