Computer Science and Artificial Intelligence Laboratory WWW '24: Companion Proceedings of the ACM on Web Conference May 13–17, 2024, Singapore, Singapore In this work, we aim to manipulate and share an entire sparse dataset with a third party privately. As our first main result, we prove that any differentially private mechanism that maintains a reasonable similarity with the initial dataset is doomed to have a very weak privacy guarantee. Next, we consider a variation of k-anonymity, which we call smooth-k-anonymity, and design a simple large-scale algorithm that efficiently provides smooth-k-anonymity. We further perform an empirical evaluation and show that our algorithm improves the performance in downstream machine learning tasks on anonymized data. 2024-06-03T19:20:55Z 2024-06-03T19:20:55Z 2024-05-13 2024-06-01T07:47:38Z Article http://purl.org/eprint/type/ConferencePaper 979-8-4007-0172-6 https://hdl.handle.net/1721.1/155161 Epasto, Alessandro, Esfandiari, Hossein, Mirrokni, Vahab and Munoz Medina, Andres. 2024.
