The world of communications wiretaps (whether on the phone or the internet) is often not fully understood - neither how they function nor what the risks are for civil liberties, especially for those dealing with sensitive information such as journalists and their sources. Wiretappings, internet tappings, surveillance, parametric wiretapping: how they work, who makes them, how they are made, how the results are used. This workshop will provide advice on the protection of communications privacy through the application of common sense and the use of free and open cryptographic technologies.
