AI0-001 AI Security Practice Question
A data science team needs to implement privacy-preserving ML for a healthcare model. They require that individual patient records cannot be distinguished in the training output. Which technique should be applied?
⚠ Common exam trap
The AI0-001 exam often tests the misconception that federated learning alone provides privacy, but without differential privacy, federated learning can still leak individual patient data through model inversion or membership inference attacks.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Differential privacy
Differential privacy is the correct technique because it adds calibrated noise to the training process or query outputs, ensuring that the inclusion or exclusion of any single patient record does not significantly affect the model's output. This provides a formal mathematical guarantee that individual records cannot be distinguished, which directly meets the requirement for privacy-preserving ML in healthcare.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Differential privacy
Why this is correct
Correct. Differential privacy provides formal guarantees against membership inference.
- ✗
Homomorphic encryption
Why it's wrong here
Homomorphic encryption protects data in use but does not prevent membership inference.
- ✗
Model pruning
Why it's wrong here
Pruning reduces model size, not privacy.
- ✗
Federated learning
Why it's wrong here
Federated learning keeps data local but does not guarantee indistinguishability.
