Censorship-Resilient Communications through Information Scattering

Abstract

The aim of this paper is to present a new idea on censorship-resilient communication Internet services, like blogs or web publishing. The motivation of this idea comes from the fact that in many situations guaranteeing this property is even matter of personal freedom. Our idea leverages: i) to split the actual content of a message and to scatter it through different points of retrieval; ii) to hide the content of a splitted message in a way that is clearly unidentifiable—hence involving encryption and steganography; iii) to allow the intended message recipient to correctly retrieve the original message. A further extension on this idea allows the recipient of the message to retrieve the message even if: i) some of the retrieval point are not available; ii) some retrieved data have been tampered with—their integrity has been violated.
