Privacy concerns can prevent constructing a centralized data warehouse to support data mining. For example, the Centers for Disease Control (CDC) may want to mine insurance companies' data to identify trends and patterns in disease outbreaks, such as understanding and predicting the progression of a flu epidemic. Gathering all patient data into a single warehouse increases opportunities for privacy breaches and misuse. We propose an alternative: secure collaborative computing between the parties holding the data that produce the desired data mining results, while provably preventing disclosure of private data.This project will enable knowledge discovery under the following assumptions:1. data are distributed across multiple sources, with security/privacy concerns that limit data sharing, and2. if data were gathered into a centralized warehouse, data mining tools could identify patterns or relationships that give beneficial knowledge.Developed techniques will replicate or approximate the results of centralized data mining, with quantifiable limits on the disclosure of data from each site. The goal is to develop a toolkit of privacy-preserving distributed computation techniques that can be assembled to solve specific real-world problems. By simplifying component assembly so it becomes development rather than research, widespread use of privacy-preserving distributed data mining will become feasible.

隐私问题可能会阻碍构建一个集中的数据仓库来支持数据挖掘。 例如，疾病控制中心（CDC）可能希望挖掘保险公司的数据，以确定疾病爆发的趋势和模式，例如了解和预测流感疫情的进展。 将所有患者数据收集到一个单一的数据仓库中，增加了隐私泄露和滥用的机会。 我们提出一个替代方案：安全的合作计算之间的各方持有的数据，产生所需的数据挖掘结果，同时可证明防止私人数据的披露。数据分布在多个源上，安全/隐私问题限制了数据共享;如果数据被收集到一个集中的仓库，数据挖掘工具可以识别模式或关系，提供有益的知识。开发的技术将复制或近似集中数据挖掘的结果，对每个站点的数据披露有可量化的限制。 我们的目标是开发一个隐私保护分布式计算技术的工具包，可以组装来解决特定的现实世界的问题。 通过简化组件组装，使其成为开发而不是研究，隐私保护分布式数据挖掘的广泛使用将变得可行。
