This tracabilite and of resurgence of flux pseudonymous on arrays of communication, and advantages of the flow of information, capable of to secure the traffic of clinical and its addressees

摘要

A network includes communication media transmitting streams to addressees, and a method includes: step of allocation of a cryptonymic identity to communication media by a first instance, the streams transmitted by a medium bearing a mark, as a function of its cryptonym, the cryptonymic identity of a medium being distinct from its real identity; step of reading and of analyzing the streams by a second instance, the analysis including a phase of identifying streams to their communication media by searching for similarity between the mark of the streams and the cryptonymic identity of the media, with the aid of a table listing the cryptonyms, and a phase of logging observable characteristics of the streams through the network. A behavior defined by a set of characteristics is declared typical or atypical by comparison with a given set of criteria, the table of cryptonymic identities having no link with the real identities. The invention is applied notably for combating illegal downloads, the sending of material that is unsolicited or likely to cover up identifiable malicious intentions.
