Perosonalized Differentially Private Location Collection Method with Adaptive GPS Discretization
[chapter]
2020
Communications in Computer and Information Science
Preserved Fulltext
To protect user privacy, researchers have adopted local differential privacy in data collection process. ...
Thus, we further improve the optimized binary local hash method, based on personalized differential privacy, to collect user visit frequency of each discretized region. ...
In 2018, a frequent item set discovery framework, called PrivTrie [11] , based on prefix trees was proposed. ...

To achieve this, we revisit distributed differential privacy based on recent results in secure multiparty computation, and we design a scalable and adaptive distributed differential privacy approach for ...
It aims to ensure differential privacy before data becomes visible to a service provider while maintaining high data accuracy and minimizing resource consumption on users' devices. ...
More broadly, we note that there is a rich body of theoretical work on distribution learning, frequent sequence mining, and heavy-hitter discovery both in the central and local models of DP [1, 8, 10, ...

Applying Generation Matrix to differential privacy hierarchical tree release, we propose a Generation Matrix-based optimally consistent release algorithm (GMC). ...
Starting from the local structures to study hierarchical trees is a common research method. ...
In the differentially private frequent term discovery problem studied by Ning et al. [14] , the hierarchical tree is arbitrary. Therefore, it is impossible to apply Boosting. ...
