Estimating Numerical Distributions under Local Differential Privacy
Zitao Li, Tianhao Wang, Milan Lopuhaä-Zwakenberg +2
When collecting information, local differential privacy (LDP) relieves the concern of privacy leakage from users' perspective, as user's private information is randomized before se…
Improving Frequency Estimation under Local Differential Privacy
Milan Lopuhaä-Zwakenberg, Zitao Li, Boris Škorić +1
Local Differential Privacy protocols are stochastic protocols used in data aggregation when individual users do not trust the data aggregator with their private data. In such proto…
Information-theoretic metrics for Local Differential Privacy protocols
Milan Lopuhaä-Zwakenberg, Boris Škorić, Ninghui Li
Local Differential Privacy (LDP) protocols allow an aggregator to obtain population statistics about sensitive data of a userbase, while protecting the privacy of the individual us…
Single-Component Privacy Guarantees in Helper Data Systems and Sparse Coding with Ambiguation
Behrooz Razeghi, Taras Stanko, Boris Škorić +1
We investigate the privacy of two approaches to (biometric) template protection: Helper Data Systems and Sparse Ternary Coding with Ambiguization. In particular, we focus on a priv…
Locally Differentially Private Frequency Estimation with Consistency
Tianhao Wang, Milan Lopuhaä-Zwakenberg, Zitao Li +2
Local Differential Privacy (LDP) protects user privacy from the data collector. LDP protocols have been increasingly deployed in the industry. A basic building block is frequency o…
