While the announcement of identity information in an initial mechanism relied on the fact that it could be hidden inside data exchanges with portals (steganography, etc), the mechanism proposed here does not require to be resistant to filtering at all. Instead, this new mechanism executes a polling operation to well-known portals in order to check whether a channel exists to these portals. The polling is done in such a way that it cannot be distinguished from a regular HTTP request, therefore it can only be filtered out at the expense of disturbing normal user operations at the same time. A more detailed description of the announcement of identity information in this context is given on Fig. 1: 1 2
