The big story here is that iOS and Android are *actively* providing tracking IDs for devices and sending them to anyone who asks.https://twitter.com/feross/status/920733574688624647 …
You can add location information to your Tweets, such as your city or precise location, from the web and via third-party applications. You always have the option to delete your Tweet location history. Learn more
Googling "mobile advertising ID" yields lots of hits marketing this crap to advertisers, little technical info on mechanism/mitigation.
I dunno about Android but IIRC iOS has a semi-anonymized advertising IDs
IIRC they're unique per device&app combo
That's utterly non-anonymous. Which seems to be the point of the paper.
It's less bad than what was there before, which was unique per device and shared between apps...
Is this the one controlled by Settings -> Privacy -> Advertising? Is there any way to turn it off without manually resetting it over & over?
I dunno at all about iOS settings (the thing I'm referring to which existed before was the iOS UDID)
It’s my understanding that the iOS-provided advertising ID is the same across all apps.
Turns out you're right - the "advertisingIdentifier" is per-device. "identifierForVendor" varies per app (vendor)
