Locally differentially private
Witryna22 lip 2024 · Context. Differential privacy is a promising approach to privacy-preserving data analysis. Differential privacy provides strong worst-case guarantees about the harm that a user could suffer from participating in a differentially private data analysis, but is also flexible enough to allow for a wide variety of data analyses to be performed with … WitrynaLDP protocols (such as Google’s RAPPOR) have been deployed in real-world scenarios. In these protocols, a user encodes his private information and perturbs the encoded value locally before sending it to an aggregator, who combines values that users contribute to infer statistics about the population. In this paper, we introduce a …

Witrynawhere the upper bound is obtained by a new method called Differentially Private Iterative Hard Thresholding (DP-IHT), which is interesting in its own right. 1 Introduction In the paper, we study the locally differentially private version of the high dimensional sparse linear regression problem, where each user i¸[n]holds a data record .x i;y i ... WitrynaHowever, the accuracy of existing locally differentially private frequent items mining methods decreases significantly with the increase in the dimensions of data to be collected. In this paper, we propose a new locally differentially private frequent item mining method for high-dimensional data, which decreases the dimension used for …
Witryna24 maj 2024 · The basic LDP frequent oracle (FO) protocol enables an aggregator to estimate the frequency of any value. But when each user has a set of values, one needs an additional padding and sampling step to find the frequent values and estimate their frequencies. In this paper, we formally define such padding and sample based … WitrynaTo address these concerns, we propose unstructured user-generated data, in the form of reviews, check-ins, a local differentially private mechanism that is based on perturb- photos, and videos. These provide a rich and detailed (if somewhat ing hierarchically-structured, overlapping -grams (i.e., contiguous non-uniform) description of the real ...

Specifically, we develop a locally private mechanism to perturb and compress node features, which the server can efficiently collect to approximate the GNN's neighborhood aggregation step. Furthermore, to improve the accuracy of the estimation, we prepend …
