Privacy in future computing environments

这项研究的目标是开发软件技术，以提高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。最近推出了许多收集和提供个人信息的服务。例如，基于网络的电子邮件或搜索服务，如谷歌提供的服务，存储用户的电子邮件和搜索行为。在线画廊，如雅虎！的S“flickr”服务，保存一个人的照片。Bell Canada提供了一项名为“Seek&Find”的服务，该服务可以追踪装有GPS的手机，这样人们就可以找到他们的朋友。隐私是这类服务的一个主要问题。也就是说，服务存储的有关个人的信息不应发布给第三实体，除非该个人定义了允许此发布的隐私首选项。这些新服务与隐私相关的另一个问题是，它们可能会被破解。例如，手机运营商T-Mobile网络的入侵者在七个月的时间里读取了数百名客户的电子邮件和个人文件。在这项研究中，我们调查了一些软件技术，这些技术可以限制服务(以及任何进入服务的入侵者)在指定和实施个人隐私偏好期间获取的个人信息量。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，使他们能够在不损害隐私的情况下从这些服务中受益。

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.
