WebThe algorithm is built on top of the celebrated Flajolet-Martin (FM) sketch. They show that FM-sketch is differentially private as is, as long as there are ln(1/delta)/(epsilon gamma ) distinct elements in the data set. Finally, experiments show that algorithms achieve strong utility while providing strong privacy guarantee.
