Online social networks are major hubs of communications that are used to share information by societies worldwide. However, the ability to freely communicate on these platforms is increasingly restricted in countries across the globe and existing technological solutions do not fully address the needs of affected communities. In this paper we explore the design process of SecurePost, a novel tool that allows verified group anonymity to those communicating publicly on online social networks. We present survey-based research and ethnographic interviews of communities vulnerable to censorship conducted in Zambia, Turkey, and Mongolia between 2013 to 2016. We use analysis of this data to ground our work. We explore needs and requirements of users such as modes of censorship, resistance to network disruption, and appropriate platform consideration. We outline our technological solution and expand on how on-the-ground research of user communities guides technological requirements.

用户驱动的免费语音应用程序，用于匿名和经过验证的在线，公共团体讨论

在线社交网络是主要的通讯枢纽，全世界的社会都用来共享信息。但是，在全球范围内的国家/地区，在这些平台上进行自由通信的能力越来越受到限制，现有的技术解决方案无法完全满足受影响社区的需求。在本文中，我们探讨了SecurePost的设计过程，SecurePost是一种新颖的工具，可让经过验证的团体匿名性与那些在在线社交网络上公开交流的人保持匿名。我们介绍了2013年至2016年之间在赞比亚，土耳其和蒙古开展的针对易受审查制度影响的社区的基于调查的研究和人种学访谈。我们使用对这些数据的分析作为我们工作的基础。我们探索用户的需求和要求，例如审查模式，对网络中断的抵抗力以及适当的平台考虑因素。
