Privacy in future computing environments

这项研究的目标是开发软件技术，以增加个人的隐私，这些个人希望从管理或利用个人信息的新兴服务中受益。最近推出了许多收集和提供个人信息的服务。例如，基于web的电子邮件或搜索服务（如b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Yahoo！facebook的“flickr”服务，保存一个人的照片。加拿大贝尔公司提供“寻找”服务，可以追踪装有gps的手机，例如，人们可以找到他们的朋友。隐私是这类服务的主要关注点。也就是说，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。这些新服务的另一个与隐私相关的问题是它们可能被侵入。例如，一名入侵者侵入了手机运营商T-Mobile的网络，在7个月内读取了数百名客户的电子邮件和个人文件。在本研究中，我们研究了在规范和执行个人隐私偏好期间限制服务（以及任何进入服务的入侵者）学习的个人信息数量的软件技术。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.
