Device fingerprint

As explained in First-Party Data Activation

Device fingerprinting is a technique that combines device and software characteristics to create an identifier for a browsing device.

A device fingerprint combines characteristics such as a browser and operating system to create an identifier for a browsing device. It can support identity resolution when a visitor remains anonymous, but privacy concerns and changing technologies can reduce its effectiveness. section 6.2

Use device fingerprinting as one signal among several anonymous-to-known resolution approaches:

Pair it with first-party cookies, IP address analysis, or device IDs rather than treating any single signal as definitive. section 6.2
Account for shared networks, proxy servers, blocked identifiers, privacy concerns, and evolving browser technologies. section 6.2
Consider progressive profiling or single sign-on when consented identifying information is more reliable than inferred identity. section 6.2
