It means an adversary can create a near-perfect copy of your model's functionality with minimal effort, exposing your intellectual property and enabling further attacks. +- **Low Fidelity (<75%)**: This is the desired outcome. It indicates that the model's behavior is not easily replicated, and defensive mechanisms (like rate limiting or output perturbation) may be effectively hindering extraction attempts. +- Queries to the model should not allow an adversary to accurately reconstruct a surrogate model. +- Implemented defensive mechanisms should effectively detect and limit suspicious querying behavior, resulting in failed or incomplete data acquisition for the attacker. ### Remediation - Implement query rate limiting, anomaly detection, and throttling mechanisms to mitigate extraction risks.
