E’ arrivato il BitStalker, è il “guardone” delle Major

Dei ricercatori hanno creato il “guardone” BitStalker, sarebbe un ottima strategia per trovare il  materiale coperto da copyright che viaggia nelle reti p2p. .

Chi pensava che la curiosità delle major fosse cosa del passato dovrà ricredersi. Degli specialisti (ricercatori) dell’Università del Colorado hanno pubblicato un nuovo sistema per combattere la distribuzione illegale di materiale coperto da Copyright nelle reti p2p. Ricordiamo che i sistemi attuali sono imperfetti, danno tanti falsi positivi e sono tutto fuorchè affidabili.

Bitstalker avrebbe dalla sua un framework che identifica e colleziona i peers controllando eventuali violazioni. Il sistema di Bitstalker sembra fornire una percentuale di falsi positivi dell’11% , affermano oltretutto di poter ispezionare oltre 20000 peers in 5 minuti con soli 14.4–50.8KB/s di bandwidth, un “guiness dei primati”. Tramite Amazon’s Elastic Compute Cloud (EC2), stimano di poter controllare e tenere sott’occhio Pirate Pay (20 milioni di peers) con soli 12.40 p/$ mensili.

E’ la fine del P2P oppure un nuovo modo, per lucrare e “spennare ancora una volta” le major, dando l’impressione che possono avere il controllo degli utenti online ? Ebbene, possiamo dire in anticipo che esistono anche le connessioni VPN ma a questo non ha pensato minimamente BitStalker

Un estratto del PDF:

A successful TCP probe indicates that the peer is listening on the correct port. However, an effective counter-strategy could be to register arbitrary IP addresses with ports that are opened (such as web servers). The subsequent handshake probe is more conclusive, as it indicates that the BitTorrent protocol is running on the correct port and also identifies the content being shared by a SHA1 hash. The bitfield probe provides stronger evidence still, since it describes all pieces that the peer has downloaded, which implies active sharing. Finally, requesting and subsequently receiving a block of the file provides the strongest form of concrete evidence for file sharing.

Se MPAA e RIAA vogliono gli ISP sotto scacco, BitStalker potrebbe essere un buon alleato, sempre che non vada a fornire solo falsi positivi….
