摘要： 大多数BT流量识别是一种粗粒度的识别方法，为提高BT流量的识别效率，提出一种面向BT的特定信息传播的细粒度监测方法。根据监测的目标文件，按BT协议的格式提取文件特征，建立样本特征库。利用客户端之间的数据传输的特征字串来识别传输的BT文件，并提取特征信息，再与样本特征库进行匹配判断，以达到对特定信息传播的监测。实验结果表明，该方法可以对特定信息进行识别，提高识别的准确性。

Abstract: Presently, many of discriminating methods are coarse-grained. In order to advance the efficiency, this paper introduces a method to indentify the specific files by fine-grained. It builds the samples according to character of the aim-files, picks up the character of BitTorrent(BT) downloading, and compares them. Experiment shows this method can indentify the specific files, and at the same time, enhance the accuracy of the identification.
