ITR - (ASE+NHS) - (dmc+int): Privacy-Preserving Data Integration and Sharing

在数据库社区中，集成和共享来自多个来源的数据一直是一个长期的挑战。这一问题在许多情况下是至关重要的，包括企业和组织的数据整合、互联网上的数据共享、政府机构之间的合作以及科学数据的交换。许多具有国家重要性的应用，如应急准备和响应；以及许多科学领域的研究，都需要参与者之间集成和共享数据。由于无法确保隐私，数据集成严重受阻。如果没有隐私框架，消息来源不愿分享他们的数据。问题包括害怕泄露机密信息以及保护个人隐私的法规。虽然在不公开数据的情况下计算分布式数据的聚集方面已经取得了进展；例如，保护隐私的分布式数据挖掘，但它假定数据集成问题(模式匹配、记录链接)已经得到解决。因此，缺乏隐私保护的数据集成框架成为部署数据集成的关键瓶颈。该项目将开发创建和管理联合数据库所需的技术，同时控制私有数据的泄露。虽然重点将放在保护隐私的数据整合的一般技术上，但该项目将在各种但特别相关的问题领域开展工作，包括科学研究和应急准备。来自这些领域的专家参与开发和测试这些技术，将确保对国家重要领域产生影响。

Integrating and sharing data from multiple sources has been a long-standing challenge in the database community. This problem is crucial in numerous contexts, including data integration for enterprises and organizations, data sharing on the Internet, collaboration among government agencies, and the exchange of scientific data. Many applications of national importance, such as emergency preparedness and response; as well as research in many scientific domains, require integrating and sharing data among participants.Data integration is seriously hampered by an inability to ensure privacy. Without a privacy framework, sources are reluctant to share their data. Problems include fear of disclosing confidential information as well as regulations protecting individual privacy. While there has been progress in computing aggregations of distributed data without disclosing that data; e.g., privacy-preserving distributed data mining, it assumes data integration problems (schema matching, record linkage) are solved. As a consequence, the lack of a privacy-preserving data integration framework has become a key bottleneck to deploying data integration.This project will develop the technology needed to create and manage federated databases while controlling the disclosure of private data. While the emphasis will be on general techniques for data integration that preserve privacy, the project will work in the context of diverse but particularly relevant problem domains, including scientific research and emergency preparedness. Involvement of domain experts from these fields in developing and testing the techniques will ensure impact on areas of national importance.
