Decentralized communication against surveillance and privacy violation

摘要

The Internet is one of the main communication platforms of our society. In many countries, communication contents and patterns are surveilled aiming to identify, punish or block undesired ideas. I focus with my research on fully decentralized and secure communication platforms which cannot be surveilled or switched off, on Android-based wireless mesh networks which support local communication that do not pass through the Internet, as well as on concepts for Internet-based democracy. My contributions aim for a practical usability in form of prototypes and software provided to potential users.
