Private Data Warehouse Query

信息和通信技术(ICT)极大地改变了世界的社会和经济格局。“从数据到知识”是澳大利亚国家信息和通信技术公司认识到的优先挑战之一。然而，对隐私的担忧可能会阻碍这一目标的实现。这个项目的目的是在不侵犯用户对数据仓库的查询隐私的情况下，实现从数据到知识的转变。本项目的研究成果将为私有数据仓库查询的研究开辟新的方向，并适用于证券交易所数据仓库和医药数据仓库中用户不愿向数据仓库运营商透露其查询的情况。

Information and Communications Technology (ICT) has dramatically altered the world's social and economic landscape. 'From data to knowledge' is one of priority challenges recognized by National ICT Australia. However, privacy concern may prevent it from realisation. This project aims to fulfil 'from data to knowledge' without breaching privacy of user's queries to a data warehouse. The outcomes of this project will create new directions in the research of private data warehouse query, and are applicable to stock exchange data warehouses and pharmaceutical data warehouses, where the user is reluctant to reveal his query to the data warehouse operator.
