Behavioral Fingerprinting

← all concepts

Definition

Behavioral fingerprinting is the use of distinctive response patterns to identify which model produced an output — useful for attribution and forensics, useful for adversaries trying to confirm what they’re talking to. Fingerprints can come from word choice, refusal patterns, calibration quirks, or deliberately embedded signals.
