  • Method of tracing and of resurgence of pseudonymized streams on communication networks, and method of sending informative streams able to secure the data traffic and its addressees
    Patent number: 9225618
    Abstract: 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.
