Method and device for transmitting or exchanging anonymous information within a trusted network

Abstract

A device and a method for the anonymous transmission of information, the transmission being a point-to-multipoint communication or a multipoint-to-multipoint communication between members of one and the same trusted network, a trusted network being predefined by a plurality of members and a plurality of independent proxies, the communication within a trusted network taking place on an anonymization network platform that masks the IP addresses of the members of the trusted network, the method being computer-implemented and comprising steps of: a member of a trusted network, comprising N' members and N proxies, generating a plurality N of complementary data fragments, from an initial data packet, such that recombining the N complementary fragments makes it possible to reconstruct the initial data packet; the sending member transmitting, via the anonymization network platform, each generated complementary fragment to an independent proxy from among the N proxies, respectively; each independent proxy retransmitting, via the anonymization network platform, the complementary fragment received from the sending member to the plurality N′ of members of the trusted network; and each receiving member of the trusted network recombining the plurality N of received complementary fragments in order to reconstruct the initial data packet.
