PANDA: Policy-aware Location Privacy for Epidemic Surveillance
Yang Cao, Shun Takagi, Yonghui Xiao +2
In this demonstration, we present a privacy-preserving epidemic surveillance system. Recently, many countries that suffer from coronavirus crises attempt to access citizen's locati…
Toward a view-based data cleaning architecture
Toshiyuki Shimizu, Hiroki Omori, Masatoshi Yoshikawa
Big data analysis has become an active area of study with the growth of machine learning techniques. To properly analyze data, it is important to maintain high-quality data. Thus,…
Protecting Spatiotemporal Event Privacy in Continuous Location-Based Services
Yang Cao, Yonghui Xiao, Li Xiong +2
Location privacy-preserving mechanisms (LPPMs) have been extensively studied for protecting users' location privacy by releasing a perturbed location to third parties such as locat…
When and where do you want to hide? Recommendation of location privacy preferences with local differential privacy
Maho Asada, Masatoshi Yoshikawa, Yang Cao
In recent years, it has become easy to obtain location information quite precisely. However, the acquisition of such information has risks such as individual identification and lea…
Making View Update Strategies Programmable - Toward Controlling and Sharing Distributed Data -
Yasuhito Asano, Soichiro Hidaka, Zhenjiang Hu +10
Views are known mechanisms for controlling access of data and for sharing data of different schemas. Despite long and intensive research on views in both the database community and…
A View-based Programmable Architecture for Controlling and Integrating Decentralized Data
Yasuhito Asano, Soichiro Hidaka, Zhenjiang Hu +9
The view and the view update are known mechanism for controlling access of data and for integrating data of different schemas. Despite intensive and long research on them in both t…
Quantifying Differential Privacy in Continuous Data Release under Temporal Correlations
Yang Cao, Masatoshi Yoshikawa, Yonghui Xiao +1
Differential Privacy (DP) has received increasing attention as a rigorous privacy framework. Many existing studies employ traditional DP mechanisms (e.g., the Laplace mechanism) as…
