Claim 11:
12. 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:
generating a set of centroids, wherein each centroid indicates a position in a distribution space representing image representations of sensitive data instances;
determining a plurality of distances, wherein each distance of the plurality of distances indicates a corresponding distance between a corresponding position of a corresponding image representation and each centroid of the set of centroids;
based on determining the plurality of distances, generating a first set of assignments for the set of sensitive data instances, wherein each assignment of the first set of assignments assigns an associated image representation of the first set of image representations to an associated cluster of a set of clusters; and
updating iteratively, based on the first set of assignments, the set of centroids based on generating a plurality of mean positions, wherein each mean position of the plurality of mean positions indicates a mean position of image representations associated with a given cluster of the set of clusters.
