Cross‑Device Tracking

Tracking

Tracking Device/Browser Fingerprinting Advertising ID

Identity resolution across devices and platforms.

Definition

Cross‑device tracking performs device graphing using deterministic signals (accounts, identifiers) and probabilistic matching (IP, fingerprints, behavior) to link devices.

In plain English Identity resolution across devices and platforms.

Why this matters

Why it matters: It increases linkability and undermines per-device privacy controls.

Example

Example: Device graph services matching household IP + behavioral signals.
