Privacy Engineering

Which of the following is MOST important for helping ensure data privacy when machine learning (ML) is used to train AI models?

  • A Data shuffling techniques to protect privacy
  • B Differential privacy mechanisms to anonymize training data
  • C Data enrichment methods to enhance model performance
  • D Data validation techniques to ensure integrity
Explanation

Differential privacy introduces a formal, quantifiable privacy guarantee that limits what can be inferred about any individual training record from a model or its outputs. In contrast, data shuffling alone does not establish such a privacy guarantee, while enrichment and validation primarily address model performance and data integrity. NIST describes differential privacy as a framework for quantifying privacy loss and notes its use in privacy-preserving machine learning.
