Which Cloud Data Loss Prevention API technique is best for tracking changes in bonus compensation without exposing individual data?

1. RedactionConfig

2. CryptoReplaceFfxFpeConfig

3. InspectConfig

4. De-identifyConfig

The correct answer is: CryptoReplaceFfxFpeConfig

The best technique for tracking changes in bonus compensation without exposing individual data is through the use of CryptoReplaceFfxFpeConfig. This approach allows you to perform format-preserving encryption (FPE), which means that the data retains its original format (e.g., numeric values for bonus amounts) while being securely encrypted. This is crucial for situations like tracking compensation where maintaining the data type and the overall statistical structure is important for analysis, such as calculating average bonuses or performing trend assessments. By using this method, sensitive information can be safeguarded, ensuring that individual records cannot be deciphered or exposed, while still permitting authorized insights into patterns and aggregate data. In a financial context where compliance and privacy are paramount, CryptoReplaceFfxFpeConfig allows organizations to adhere to regulations while still making use of the data for legitimate purposes. The other techniques serve different functionalities, such as redacting information, inspecting for sensitive data, or de-identifying data entirely, which may not align with the need to track changes accurately while keeping those changes secure and within their original context.
