DIGITAL PLATFORMS, THE NEW PRIVACY CHAMPIONS? BETWEEN MYTHS AND REALITIES
summary
Platforms roll out local differential privacy for browsing and maps, trial federated learning for on-device model updates, and an exposure notification API for contact tracing while advertising shifts to permissioned ATT frameworks; claims of “privacy by design” coexist with built-in gatekeeping: app store permission architectures, Play Store privacy labels, and backend access to raw data. Technical choices favor “soft” PETs that keep platforms in control; hard crypto (MPC, homomorphic) is workable for simple aggregates but rarely deployed at scale. Regulatory fixes focus on disclosure and enforcement.
