It’s been about a year since Apple rolled out new mobile settings that prohibit apps from tracking iPhone users without their explicit consent.
Specifically, Apple prohibited developers from accessing devices’ Identifier for Advertisers — an alphanumeric string that can be used to track people from app to app.
While the company’s move appears to have curtailed cross-app tracking, the new settings are hardly foolproof. On the contrary, some app developers deploy a workaround that allows them to continue tracking mobile users from app to app. That’s according to a recent paper by University of Oxford researchers.
