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.

该项目开发了为公民提供有关技术信息的信息的信息，以提供信息的访问。互联网用户需要客观，独立的第三方服务，以帮助他们确定其互联网服务提供商或政府是否限制了对内容，特定协议或以其他方式退化服务的访问。为了实现这一目标，我们（1）监视试图阻止或操纵Internet内容和通信的尝试； （2）评估现实部署中各种审查机制的规避机制}。该项目开发了一个大规模的测量和监视服务，可测量网络的可达性和性能，从各种访问网络到各种互联网服务；注入ISP或政府正在限制或以其他方式进行对各种应用程序和服务的访问；并检测试图篡改向用户提供的信息进行篡改。该项目还研究了互联网用户可用的有关审查制度和信息篡改信息的信息的政策后果。它将提供有关世界各国的审查制度和信息篡改程度的最新信息，以及国家用来实施审查制度和阻止审查制度规避工具的信息。通过实时门户以及定期的书面报告和学术出版物来传播发现。
