We study data integrity verification in peer-to-peer media streaming for content distribution. Challenges include the timing constraint of streaming as well as the untrustworthiness of peers. We show the inadequacy of existing data integrity verification protocols, and propose Block-Oriented Probabilistic Verification (BOPV), an efficient protocol utilizing message digest and probabilistic verification. We then propose Treebased Forward Digest Protocol (TFDP) to further reduce the communication… CONTINUE READING
