Which AI workload mitigation strategy best addresses model inversion attacks that threaten data confidentiality?

Differential privacy is a strategy designed to protect data confidentiality by ensuring that the output of a machine learning model does not expose sensitive information about individual data points. In the context of model inversion attacks, where attackers try to infer confidential data from the model, differential privacy introduces noise into the model’s output in a way that prevents attackers from accurately reconstructing the input data. This helps safeguard against attacks that threaten the privacy of the data used to train the model.

Secure multi-party computation is useful for enabling collaborative computation on encrypted data but does not specifically address model inversion attacks. Encryption is important for securing data at rest or in transit but does not directly protect against model inversion attacks. Model hardening refers to general measures to make models more robust to adversarial attacks, but it does not directly mitigate the specific risk of model inversion attacks related to data confidentiality.
