Patent Searching and Data


Title:
通信ネットワーク上の仮名にされたストリームの追跡および復活方法、およびデータトラフィックおよびそのアドレスを安全に保護することができる情報ストリームの送信方法
Document Type and Number:
Japanese Patent JP2011522336
Kind Code:
A
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. The invention is applied notably for combating illegal downloads, the sending of material that is unsolicited or likely to cover up identifiable malicious intentions.
