Tecnologia P2P continua a correr à frente dos esforços para controlar a pirataria

As its name suggests, the software lets computer users share large chunks of data. But unlike other popular file-sharing programs, the more people swap data on BitTorrent, the quicker it flows — and that includes such large files as feature films and computer games.
Because of its speed and effectiveness, BitTorrent steadily gained in popularity after the recording industry began cracking down last year on users of Kazaa, Morpheus, Grokster and other established file-sharing software.
The program now accounts for as much as half of all online file-sharing activity, says Andrew Parker, chief technology officer of Britain-based CacheLogic, which monitors such traffic.
"BitTorrent is more of a threat because it is probably the latest and best technological tool for transferring large files like movies," said John Malcolm, senior vice president of anti-piracy operations for the Motion Picture Association of America. "It is unusual, perhaps unique, in that the moment you start downloading you are also uploading," he added. "It's what makes it so efficient."
Cohen created BitTorrent in 2001 as a hobby after the dot-com crash left him unemployed. He says the aim was to enable computer users to easily distribute content online — not specifically copyrighted content.
"It seems pretty clear that a lot of people are actively interested in engaging in wanton piracy," said Cohen, 29, of Bellevue, Wash. "As far as I'm concerned, they're just pushing around bits, and what bits it is they're pushing around is not really a concern of mine. There's not much I can do about it."
BitTorrent has proven to be resistant to some of the countermeasures the entertainment industry has taken to sabotage file-sharing, including a process known as file-spoofing in which incomplete or decoy versions of songs or other material are uploaded to discourage piracy.
"Spoofing is very difficult on BitTorrent, if at all possible," said Mark Ishikawa, chief executive of online tracking firm BayTSP Inc. "There's no defense for this one."
Programs such as Kazaa and Morpheus allow users to link their PCs to computer networks and then query a search engine for the file or title they're seeking. The software then churns out a list of other computers sharing the file.
The process is simple and straightforward, which makes it relatively easy to corrupt with spoofed files.
With BitTorrent, however, users don't find whole files. The program seeks out torrent files, also known as seed files, that are hosted by a number of Web sites.
The files on the Web sites are not songs or movies but serve as markers that point the way to other users sharing a given file. BitTorrent then assembles complete files from multiple chunks of data obtained from everyone who is sharing the file.
Attempts to upload bogus files to corrupt the process fail because the BitTorrent program follows a blueprint of the original file when piecing it together.
