An anonymous reader writes: NBC Universal has been granted a patent, titled "Early detection of high volume peer-to-peer networks in real-time," to try and restrict piracy of its copyrighted content. "Early detection of high volume swarms in a peer-to-peer network, including a data feed of peer-to-peer swarm activity, and an analytics engine processing the data feed and identifying the high volume swarms that have parameters that exceed a threshold. The system can include a pre-processing section for conditioning the swarm data for the analytics section. There can also be a verification section that confirms that the peer download file matches the target file," notes the patent document issued by USPTO (United States Patent and Trademark Office). "The early detection provides for enhanced anti-piracy efforts, improved allocation of network resources, and better business decision-making," it adds. NBC Universal says that the "P2P infrastructure has many advantages" but it has also led to abuses. Piracy is estimated to cost content owners billions of dollars annually. "These costs are typically passed along to the consuming public in terms of increased costs for legitimate purchased works and higher charges for increased deterrents to the piracy," NBC Universal added. The patent NBC Universal received was applied for back in 2009, but only granted last week.
