Macrovision Applies for P2P Interdiction Patents

schmecky05 writes "From Macrovision, the folks whom recently mandated "Thou shalt delete content promptly from thy Tivo" come the following 2 USPTO patent applications for Peer to Peer interdiction methods: "Interdiction of unauthorized copying in a decentralized network" and "System and methods for communicating over the internet with geographically distributed devices of a decentralized network using transparent asymetric return paths." These patent applications describe (in pain staking detail) how Macrovision interdicts on Peer to Peer networks to prevent illegal copyrighted file sharing from many locations across the globe and avoid ban lists as well."

I actually interviewed for a position on this team, albeit in operations and not development, so I might be able to shed some light than someone completely on the outside.

My understanding is that some of the hash spoofing isn't spoofing cryptographically-strong hashes; not all networks use them.

If my interviewer's claims were correct, then this technology is v. effective at taking down certain files on certain networks. I unfortunately can't say more, because my interviewer declined to say more until I signed a NDA.
