The correct answer is B. There is a high risk of exposing the actual data that is uses to generate the report.. In differential privacy, epsilon (ε) controls the privacy-accuracy trade-off. A smaller epsilon means more noise is added to the data, providing stronger privacy guarantees with less accuracy. An epsilon value greater than 1 indicates that relatively little noise has been added,

Question

You need to evaluate the potential risk of exposing personal information based on the values of epsilon and delta for differential privacy. You create a privacy report. What does an epsilon value greater than one represent?

Options

AThe privacy of data is preserved and there is limited impact on data accuracy.
BThere is a high risk of exposing the actual data that is uses to generate the report.
CThe data used in the report is very noisy.

Explanation

In differential privacy, epsilon (ε) controls the privacy-accuracy trade-off. A smaller epsilon means more noise is added to the data, providing stronger privacy guarantees with less accuracy. An epsilon value greater than 1 indicates that relatively little noise has been added, meaning the synthetic or anonymized data closely resembles the original data - which in turn means there is a high risk of exposing the actual underlying data. Option A is incorrect because low epsilon (not high) preserves privacy. Option C is incorrect because high epsilon means less noise (the data is less noisy), not more.
