Question
Ahbed wants to employ privacy controls before his model is deployed.
Which of the following should he use?
Select the two that apply.
A. Data anonymization
B. Data minimization
C. Model anonymization
D. Differential privacy
Answer
C. Model anonymization
D. Differential privacy
Explanation
Model Anonymization (C)
This technique ensures that the AI model itself does not reveal sensitive information about the training data. By anonymizing the model, it becomes resistant to attacks like model inversion or membership inference, where adversaries attempt to extract details about individuals from the model’s outputs or parameters.
For example, anonymized models obscure sensitive patterns or identifiers that could inadvertently reveal private data used during training.
Differential Privacy (D)
Differential privacy is a mathematically rigorous framework that adds carefully calibrated noise to the data or model outputs. This ensures that the inclusion or exclusion of any single individual in the dataset does not significantly affect the results, thereby protecting individual privacy.
It is particularly effective in preventing re-identification attacks and maintaining privacy while allowing meaningful analysis of aggregated data. For instance, during training, noise can be added to gradients or outputs to ensure no specific individual’s data is memorized by the model1324.
Why Not A or B?
A. Data Anonymization: While data anonymization is a valuable technique for protecting sensitive information, it is typically applied before training the model, not as a control during deployment. It focuses on removing personally identifiable information (PII) from datasets rather than addressing risks associated with the trained model itself.
B. Data Minimization: Data minimization involves collecting and retaining only the necessary data for a specific purpose, aligning with principles like GDPR compliance316. However, this principle is more relevant during data collection and preprocessing stages rather than as a deployment control.
Key Takeaways
- Model anonymization and differential privacy are critical for ensuring that an AI model does not expose sensitive information after deployment.
- These techniques safeguard against attacks targeting both the training data and the deployed model’s outputs.
- Data anonymization and minimization are important but are typically applied earlier in the AI development lifecycle.
By implementing these advanced privacy controls, Ahbed can ensure his AI system adheres to ethical standards and regulatory requirements while maintaining user trust.
