AI0-001 AI Security Practice Question
A data scientist is training a model to detect fraudulent transactions. To protect customer privacy, the team wants to ensure that the model does not inadvertently memorize and reveal sensitive information about individuals in the training set. Which technique should be applied during training?
⚠ Common exam trap
The AI0-001 exam often tests the misconception that federated learning alone guarantees privacy, when in fact it only addresses data locality and must be combined with differential privacy to prevent 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 output, ensuring that the model cannot infer whether any specific individual's data was included in the training set. This directly addresses the goal of preventing memorization and leakage of sensitive information while still allowing the model to learn useful patterns for fraud detection.
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
Differential privacy adds noise during training to bound the influence of any single data point, protecting individual privacy.
- ✗
Federated learning
Why it's wrong here
Federated learning trains across decentralized data but doesn't inherently prevent memorization; it still risks leakage from gradients.
- ✗
Homomorphic encryption
Why it's wrong here
Homomorphic encryption allows computation on encrypted data but doesn't address memorization during training.
- ✗
Model quantization
Why it's wrong here
Quantization reduces model size and speeds up inference but does not provide privacy guarantees.
