An ambitious software project for blocking copyrighted song-swapping over peer-to-peer (P2P) networks is nearly ready, though technical problems have forced its developers to limit their plans.
For much of the last year, the University of Wyoming and a company called Audible Magic tested technology that looked inside students' file swaps for copyrighted music, with an eye toward ultimately blocking the transfer of such material.
The job turned out to be harder than Audible Magic expected. On Wednesday, the company said it had given up on part of its network-spying technology and had instead teamed up with an established network-security company. The identify-and-block product still will be offered, but it will now be a joint venture between Audible Magic and security company Palisade Systems, the companies said.
"We recognised that we would have challenges trying to work with the type of bandwidth we were looking for, (such as) inside an ISP," said Audible Magic chief executive Vance Ikezoye.
The product is one of the most ambitious among those being designed to rein in unauthorised trades of copyrighted works online, and it carries with it some of the most potentially serious privacy concerns. Most other services, such as Packeteer, work by blocking or controlling the amount of bandwidth available to file-trading applications, rather than by looking inside the transmissions themselves.
Audible Magic's own technology specialises in identifying songs by their digital "fingerprints", or acoustic characteristics.
But combined with Palisade's network-security technology, it could become a powerful monitoring tool for network administrators or copyright holders. The joint product is designed to intercept all traffic on a network, make a copy of it, and then make a running examination of that copy for items such as Kazaa or Gnutella traffic.
When it finds digital packets originating from file-swapping software packages, it will compare the contents against Audible Magic's database of fingerprints. If it finds a match to a copyrighted song, it will stop the transmission of a song in progress, even if some of the file has already been transferred.
"The nice thing about content -- if you've only got half of a song, it's worthless," Ikezoye said. "I think in general it's about a third of the way in that we ID and block" an average song.
Analysts say the product is likely to be well received by universities and companies. ISPs, which are typically protective of their subscribers' privacy, might be a more difficult sell, however.
"I don't think Comcast or Verizon would voluntarily put this kind of monitoring in place," said Forrester Research analyst Josh Bernoff. "Users would consider it intrusive."
Talkback
Erm if this software is intercepting network traffic and making a copy to analyse for copyrighted material not gonna be violateing the copyright themselves. I understaand that maybe it will get a license for the stuff the RIAA want blocked thus avoiding the copyright issue o it's works but what about everything else it intercepts that there will not be a copy license for ?
I think there should be an international referrendum on copyright and intreasted corporate bodies should be banded for campaigning unless an equal amount of cash is provided to the opposing view that copyright should be reduced if not disbanded!
Information is power but how do we know who's it is. Let it all be free and we'll just have to sort out other ways of making money. I very much doubt that people will give up and go back to living in caves and telling stories. Other revenue streams will be found!
How are they going to diffentiate between non-copyrighted songs and those that are protected by a copyright?
If I am downloading a song from the public domain, they certainly don't have the righ to stop me..
The ability to copy music has been going on since the days of the wire recorder.. 78's, 33's, 45's, 8-track, VCR's, CD's, DVD's, radio and television have all been sources of copying music.
If an artist paints a picture, it is copyrighted and illegal to make a copy and SELL it. If another artist paints a similar picture, copies it and sells copies that is not illegal, as long as the buyer knows it is a copy..
MP3's are not the original music found on a music CD.. It is compressed, usually at 128bit and not the higher quality of the CD..
The RIAAA is wrong, particularly when they sue and fine a 12 year old girl who lives in Public Housing $12,000.00 and a 76 year old Grandfather who had no knowledge that his Grandson and some friends had downloaded some MP3's..
Best thing to do is boycott the record industry through this Holiday Season to let them know how you feel..
