Starting a platform for digital whistleblowing is far from simple. More and more international media are gearing up to provide an anonymous and interactive web "letterbox" with which journalistic sources can communicate securely, from simple messages to large numbers of files (data leaks). We will learn how to "set up" a system of digital whistleblowing, what to consider in terms of organizational, technical, legal and security issues as well as communication requirements. There will also be a demonstration of the anonymous whistleblowing Globaleaks software and the necessary knowledge to plan and implement a system of whistleblowing will be acquired. The Hermes Centre will provide, to all present and interested, a "hosted" Globaleaks system with which to gain experience.
