This project develops methods to provide citizens information about technologies that obstruct, restrict, or tamper with their access to information. Internet users need an objective, independent, third-party service that helps them determine whether their Internet service provider or government is restricting access to content, specific protocols, or otherwise degrading service. Towards this goal, we are (1) monitoring attempts to block or manipulate Internet content and communications; and (2) evaluating various censorship circumvention mechanisms in real-world deployments}. The project develops a large-scale measurement and monitoring service that measures network reachability and performance from a variety of access networks to various Internet services; infers whether ISPs or governments are restricting or otherwise throttling access to various applications and services; and detects attempts to tamper with information presented to users. The project also studyies the policy ramifications of making information about censorship and information tampering available to Internet users. It will provide up-to-date information about both the extent of censorship and information tampering in countries around the world and technologies countries are using to implement censorship and thwart censorship circumvention tools. Discoveries are disseminated through real-time portals and through regular written reports and academic publications.

本项目制定方法，向公民提供有关阻碍、限制或篡改其获取信息的技术的信息。互联网用户需要一个客观、独立的第三方服务，帮助他们确定他们的互联网服务提供商或政府是否在限制访问内容、特定协议或以其他方式贬低服务。为了实现这一目标，我们正在(1)监控阻止或操纵互联网内容和通信的企图；(2)评估现实世界部署中的各种审查规避机制。该项目开发了一种大规模测量和监控服务，用于测量从各种接入网到各种互联网服务的网络可达性和性能；推断isp或政府是否限制或以其他方式限制对各种应用程序和服务的访问；并检测对呈现给用户的信息进行篡改的企图。该项目还研究了向互联网用户提供有关审查和信息篡改的信息的政策后果。它将提供有关世界各国审查和信息篡改程度的最新信息，以及各国用于实施审查和挫败审查规避工具的技术。发现通过实时门户网站和定期书面报告和学术出版物传播。
