CC* Data: ImPACT - Infrastructure for Privacy-Assured compuTations

该项目解决了分布式计算中的一个基本问题：以安全的方式对敏感或私有数据进行计算的能力。这对于多机构和跨学科的数据共享和分析至关重要，特别是在卫生相关领域和社会科学领域。该项目建立并加强了几个网络基础设施元素，这些元素是通过其他国家科学基金会奖项开发的，已经是现有研究基础的一部分。通过开发在不同协作环境中安全共享私有数据的方法，Impact(隐私保证计算基础设施)降低了在科学协作中使用隐私受限数据的障碍。它减少了发现时间，并为研究开辟了新的途径。ImPACT支持各种研究场景，这些场景需要跨子域集成数据，其中相关数据集由不同的利益相关者持有。Impact的目标是实现利益相关者拥有的数据集之间的合作处理，同时尊重个人所有者的隐私政策，并提供一个可供其他机构随时使用的协作模式。该项目汇集了一个团队，其中包括来自北卡罗来纳大学、杜克大学和印第安纳大学的社会科学研究人员、网络基础设施专家以及分布式系统和安全专家。北卡罗来纳州达勒姆市成立的一个非营利性组织提供了该项目中使用的一些数据集。为了实现端到端的数据流，Impact建立在NSF在杜克大学和北卡罗来纳大学校园的网络基础设施计划以及全球网络创新环境(GENI)计划的先前投资的基础上，以支持各自虚拟基础设施内的直接数据传输。通过支持协作者之间的三种不同信任模型，该项目开发了在网络、数据管理、安全和隐私保护方面具有最佳实践的各种方法，以适应各种协作方案。数据访问、共享、处理和发布集成到隐私感知系统中，允许科学家使用他们自己的工具，并建立在支持网络基础设施技术的基础上，如Datverse、CyVerse和开放资源控制体系结构(ORCA)控制软件。

This project addresses one of the fundamental problems in distributed computing: the ability to compute on sensitive or private data in a secure manner. This is critically important for multi-institution and cross-disciplinary sharing and analysis of data, particularly in health-related fields and the social sciences. This project builds upon and enhances several cyberinfrastructure elements which have been developed through other NSF awards and are already part of the existing research base. By developing methods for securely sharing private data in different collaborative settings, ImPACT (Infrastructure for Privacy-Assured CompuTations) lowers the barriers to using privacy-restricted data in scientific collaborations. It reduces the time to discovery and opens new avenues for research.ImPACT enables a variety of research scenarios that require integration of data across subdomains where relevant data sets are held by different stakeholders. The goal of ImPACT is to enable cooperative processing across the stakeholder-owned datasets, while respecting the privacy policies of the individual owners, and to provide a model for collaboration that could be readily used by other institutions. The project brings together a team that includes social science researchers, cyber-infrastructure experts, and distributed systems and security experts from the University of North Carolina, Duke University, and Indiana University. A non-profit organization formed by the city of Durham, NC provides some of the data sets that are used in the project. To enable end-to-end data flows, ImPACT builds upon prior investments by the NSF Campus Cyberinfrastructure program at the Duke and UNC campuses, as well as the Global Environment for Network Innovations (GENI) program to support straightforward transfers of data within the respective virtual infrastructures. By supporting three different trust models between collaborators, the project develops diverse methodologies with best practices in networking, data management, security, and privacy preservation to accommodate a variety of collaborative scenarios. Data access, sharing, processing, and publishing are integrated into privacy-aware systems that allow scientists to use their own tools and that build upon enabling cyberinfrastructure technologies like Dataverse, CyVerse, and the Open Resource Control Architecture (ORCA) control software.
