Utility-optimized Local Differential Privacy Joint Distribution Estimation Mechanisms [PDF]

Jisuanji kexue, 2023
Compared with traditional centralized differential privacy,local differential privacy(LDP) has the advantage of not re-lying on trusted third parties,but it also has the problem of low data utility.The utility-optimized local differential privacy(ULDP ...

Fldp: Flexible Strategy For Local Differential Privacy

ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022
Local differential privacy (LDP), a technique applying unbiased statistical estimations instead of real data, is often adopted in data collection. In particular, this technique is used with frequency oracles (FO) because it can protect each user's privacy and prevent leakage of sensitive information.

Edge Local Differential Privacy for Dynamic Graphs

, 2023
AbstractHuge amounts of data are generated and shared in social networks and other network topologies. This raises privacy concerns when such data is not protected from leaking sensitive or personal information. Network topologies are commonly modeled through static graphs.

Estimating Numerical Distributions under Local Differential Privacy [PDF]

Proceedings of the 2020 ACM SIGMOD International Conference on Management of Data, 2020
When collecting information, local differential privacy (LDP) relieves the concern of privacy leakage from users' perspective, as user's private information is randomized before sent to the aggregator. We study the problem of recovering the distribution over a numerical domain while satisfying LDP.

Answering range queries under local differential privacy [PDF]

Proceedings of the VLDB Endowment, 2019
Counting the fraction of a population having an input within a specified interval i.e. a range query, is a fundamental data analysis primitive. Range queries can also be used to compute other core statistics such as quantiles, and to build prediction models.
