CAREER: A Comprehensive Framework for Disappearing Data

许多技术和环境力量正在增加数据隐私对企业和个人的重要性。 这些力量包括将数据迁移到Web服务，服务和ISP对大量数据和通信进行永久存档，以及迫使个人和组织披露私有（甚至加密）数据的法律的行动。 在这种情况下，传统的加密是不够的解决方案，从而在日益互联的数字世界中保护我们的数字隐私带来了新的挑战。 该项目通过创建一个原则性的框架来解决这些挑战，该框架用于保护过去数据的隐私-例如电子邮件提供商维护的电子邮件副本-以防意外，恶意和法律的披露，甚至是可以访问解密密钥的实体。 该框架由底层技术机制和原型应用程序组成;这些机制和原型应用程序协同开发，以确保整个框架的最广泛适用性。 这些原型应用程序本身也直接解决了广泛类别的个人的隐私需求，从希望增强其电子邮件通信的隐私的家庭用户到希望改善电子投票审计日志的隐私的投票机制造商。

Numerous technical and environmental forces are increasing the importance of data privacy for businesses and individuals alike. These forces include the migration of data to Web services, the permanent archiving of large volumes of data and communications by services and ISPs, and legal actions that are forcing individuals and organizations to reveal private (and even encrypted) data. Traditional encryption is an insufficient solution under these conditions, thereby creating new challenges to preserving our digital privacy in an increasingly inter-connected and digital world. This project tackles these challenges through the creation of a principled framework for protecting the privacy of past data -- such as copies of emails maintained by an email provider -- against accidental, malicious, and legal disclosure, even to entities who have access to the decryption keys. This framework consists of both underlying technical mechanisms and prototype applications; these mechanisms and prototype applications are developed in concert to ensure the broadest applicability of the overall framework. These prototype applications, by themselves, also directly address the privacy needs of broad classes of individuals, ranging from home users wishing to enhance the privacy of their email communications to voting machine manufacturers wishing to improve the privacy of electronic voting audit logs.
