dc.description.abstract
We propose using homomorphism density vectors to obtain
graph embeddings that are both private and expressive. Homomorphism
densities are provably highly discriminative and offer a powerful tool
for distinguishing non-isomorphic graphs. By adding noise calibrated to
each density’s sensitivity, we ensure that the resulting embeddings sat-
isfy formal differential privacy guarantees. Our construction preserves
expressivity in expectation, as each private embedding remains unbiased
with respect to the true homomorphism densities. We study the trade-off
between privacy, utility, and expressivity, both theoretically and empiri-
cally, and show that our private embeddings match the accuracy of their
non-private counterparts with increased resilience to privacy attacks.
