Privacy in future computing environments

这项研究的目标是开发软件技术，以提高那些希望从管理或利用个人信息的新兴服务中受益的个人的隐私。最近已经引入了许多收集和提供关于个人的个人信息的服务。例如，基于Web的电子邮件或搜索服务（如Google提供的服务）存储用户的电子邮件和搜索行为。 在线画廊，如雅虎！的“flickr”服务，保存一个人的照片。加拿大贝尔公司提供了一项“寻找和查找”服务，该服务跟踪装有GPS的手机，以便人们可以找到他们的朋友。 隐私是此类服务的主要关注点。也就是说，由服务存储的关于个人的信息不应该被发布给第三方实体，除非个人定义了允许这种发布的隐私偏好。对这些新服务的另一个与隐私相关的担忧是，它们可能被侵入。例如，一个入侵者进入手机运营商T-Mobile的网络，在七个月内阅读了数百名客户的电子邮件和个人文件。 在这项研究中，我们调查的软件技术，限制个人信息的数量，服务（和任何入侵者进入服务）在规范和执行个人的隐私偏好学习。我们的最终目标是让公众意识到围绕新兴服务的隐私问题，并为人们提供技术，使他们能够从这些服务中受益，而不会损害他们的隐私。

The goal of this research is to develop software techniques for increasing the privacy of individuals who want to benefit from emerging services that manage or exploit personal information. Many services that gather and provide personal information about individuals have been introduced recently. For instance, Web-based email or search services, such as those provided by Google, store a user's emails and search behavior.  Online galleries, such as Yahoo!'s "flickr" service, keep a person's pictures. Bell Canada offers a "Seek & Find" service, which tracks GPS-equipped cellphones so that, for example, people can locate their friends.  Privacy is a major concern for such services. Namely, the information stored by a service about an individual should not be released to third entities, unless the individual defines privacy preferences allowing this release. Another privacy-related concern for these new services is that they can be broken into. For instance, an intruder into the network of cellphone carrier T-Mobile read emails and personal files of hundreds of customers over seven months.   In this research, we investigate software techniques that limit the amount of personal information that a service (and any intruders into the service) learns during the specification and enforcement of an individual's privacy preferences. Our ultimate goals are to make the public aware of privacy issues surrounding emerging services and to give people technologies that allow them to benefit from these services without compromising their privacy.
