In this paper we propose a distortion-less information hiding scheme with maximum embedding capacity based on the P2P (peer-to-peer) streaming video protocol called R 2 (Random push with Random network coding). Specifically, we use the encoding vectors attached in the headers containing the coefficients used to encode the packets as our covert channel, in which we hide secret messages. We give the embedding capacities of the scheme and compare it with state-of-the-art schemes performances.
