NICT have developed a scary system that allows them to track files being exchanged along peer-to-peer networks.
They first locate the supernode and from there get information about smaller node groupings. The system lets you search for files and refine movements of data down to IP address and exact time. It can even trace files that have been altered and re-sent, and ones that are exchanged from one network to another. The oldest node in the chain is the person who originally uploaded the file…and potentially committed piracy.
NICT is currently only “investigating” files being exchanged inside Japan but surely it’s simply just a matter of time before governments and corporations start using the system. You have been warned!

Well, I suppose this was bound to happen sooner or later…
Ha, interesting system.. now the next thing would be to warn the pirates..
Interesting concept, isn’t this already being used for credit card fraud? if not it should. What about all thoses scam email we get! We should be looking at getting those guys first instead of sharing files.
Also with the software, what happen if I were to use an IP spoofer? will this continue to work? and also what happens if we are downloading a file from a country that has no copyright law, like Pakistan? can we still be sued for it?
