Claim 13:
14. The method of claim 2, wherein clustering the first sensitive data instance and the second sensitive data instance into the first cluster based on similarities between the first image representation and the second image representation further comprises:
determining a list of distances, wherein each distance in the list of distances characterizes a distance between a first test image representation and a second test image representation, wherein the list of distances is sorted by distance, and wherein the first set of image representations comprises the first test image representation and the second test image representation;
determining, based on the list of distances, a density threshold parameter, wherein the density threshold parameter indicates a point of maximum curvature corresponding to a distance within the list of distances; and
determining, based on the list of distances and the density threshold parameter, a set of clusters, wherein each cluster of the set of clusters comprises a corresponding plurality of image representations of the first set of image representations.
