Model Fingerprinting

Definition

Model Fingerprinting is a technique used to embed a unique, verifiable signature into a machine learning model, allowing its creator to assert ownership and detect unauthorized use or distribution. This “fingerprint” can be subtle and imperceptible during normal model operation but detectable through specific analysis. Its purpose is to protect intellectual property, track model usage, and deter illicit replication of proprietary AI algorithms. It provides a mechanism for proving provenance and controlling distribution.
