You can control what push notifications you see, but you can’t stop governments using them for survelillance
A senator’s open letter making it public that iPhone push notifications can be used to track users has let Apple publish a warning about the topic.
On Wednesday, Senator Wyden made a seemingly wild accusation that governments could use push notifications on iPhones and Android to spy on people. Apple immediately revealed that not only is this true, but also that the government had mandated that it not be revealed.
“When users allow an application they have installed to procure push notifications, an Apple Push Notification Service (APNs) token is generated and registered to that developer and device,” says Apple under the new heading, “Apple Push Notification Service (APNs).”
“Some apps may have multiple APNs tokens for one account on one device to differentiate between messages and multi-media,” it continues. “The Apple ID associated with a registered APNs token may be obtained with a subpoena or greater legal process.”
