Abstract

The invention discloses a passive load information monitoring method based on BitTorrent, which is used for monitoring and analyzing P2P network customizing information spreading and audiences thereof based on the BitTorrent. The method comprises the steps of: downloading required files into a local hard disk by using BitTorrent software; generating information of file samples according to existed file information; carrying out Hash processing on the information of file samples, carrying out Hash processing in load information; comparing the film samples subjected to the Hash processing with the load information subjected to the Hash encryption; comparing the load information with the load samples by adopting a character string matching method for judging; and extracting and processing obtained audience information. Because of adopting the way of carrying out the Hash encryption on the captured load data, the mode matching is carried out on the data subjected to the Hash encryption without recovering original content of the files or considering the format of a transmitted file, a plenty of computer processing time is saved.

Description

technical field

[0001] The invention belongs to the field of network security and relates to an information monitoring method, in particular to a BitTorrent-based passive load information monitoring method, which is used for monitoring and analyzing the BitTorrent-based P2P network specific information dissemination and its audience. Background technique

[0002] The document "Ho Gyun Lee, Taek yong Nam, Jong Soo Jang. The Method of P2P Traffic Detecting for P2P Harmful Contents Prevention [C]. ICACT2005. Feb 21-23, 2005, Phoenix Park, Korea" discloses a content recovery based The specific content monitoring method of the P2P file sharing system, the method firstly identifies the P2P data flow, and divides the P2P data flow into text, image and video data according to the type of transmission content. For text-type data content, the method of dictionary comparison is adopted, and the keywords carried in the text are compared with the bad information dictionary library establ...
