Question
A data scientist wants to improve her customer satisfaction prediction reports and has some ideas to improve the model. This procedure will involve copying the customer database from production to a test environment. To ensure privacy protection of customer information, the data scientist asked the privacy engineers for guidance. Which of the following Privacy Enhancing Techniques (PETs) would be best suited to support her analysis but reduce privacy risks?
A. Use sample data.
B. Use synthetic data.
C. Use anonymized data.
D. Use pseudonymized data
Answer
B. Use synthetic data.
Explanation
When a data scientist wants to improve her customer satisfaction prediction reports by copying the customer database from production to a test environment, the best Privacy Enhancing Technique (PET) to support her analysis while reducing privacy risks is to use synthetic data (Option B).
Synthetic data is generated by algorithms that mimic the statistical properties and patterns of the original dataset without containing any real customer information. This approach allows the data scientist to work with a dataset that closely resembles the original data in terms of structure and insights, but does not pose any risk of exposing sensitive customer details.
Using sample data (Option A) may not provide a comprehensive representation of the entire customer database, potentially leading to biased or inaccurate results. Anonymized data (Option C) involves removing personally identifiable information (PII) from the dataset, but it may still be vulnerable to re-identification attacks if combined with other external data sources.
Pseudonymized data (Option D) replaces personally identifiable information with artificial identifiers, but the original data can still be linked back to specific individuals if the mapping between the pseudonyms and the original identities is compromised.
In contrast, synthetic data offers several advantages:
- Privacy protection: By generating artificial data that mimics the original dataset’s properties, synthetic data eliminates the risk of exposing real customer information.
- Data utility: Synthetic data preserves the statistical patterns and relationships present in the original data, allowing the data scientist to derive meaningful insights and improve the prediction model.
- Compliance: Using synthetic data helps organizations comply with data privacy regulations, such as GDPR or CCPA, by minimizing the processing and storage of personal data.
- Flexibility: Synthetic data can be generated on-demand, enabling the data scientist to create multiple variations of the dataset for testing and validation purposes without relying on the production environment.
In summary, using synthetic data is the best Privacy Enhancing Technique for the data scientist to improve her customer satisfaction prediction model while ensuring the privacy protection of sensitive customer information.
