Abstract
A system for differential privacy is provided. In some implementations, the system performs operations comprising receiving a plurality of indices for a plurality of perturbed data points, which are anonymized versions of a plurality of unperturbed data points, wherein the plurality of indices indicate that the plurality of unperturbed data points are identified as presumed outliers. The plurality of perturbed data points can lie around a first center point and the plurality of unperturbed data points can lie around a second center point. The operations can further comprise classifying a portion of the presumed outliers as true positives and another portion of the presumed outliers as false positives, based upon differences in distances to the respective first and second center points for the perturbed and corresponding (e.g., same index) unperturbed data points. Related systems, methods, and articles of manufacture are also described.
