基于暗网3.0的加密数字货币可追踪方法

A traceable method for cryptocurrency based on dark Web 3.0

暗网是指需要通过特定配置才能登录的特殊网络。暗网通信突出的特点是匿名性,其导致暗网中滋生大量通过加密数字货币进行的违法犯罪交易,且难以被追踪。本文针对最新的暗网3.0版本提出了一种以比特币为代表的加密数字货币可追踪方法,据此设计了集暗网页面爬取、页面信息分类、比特币地址提取、比特币地址追踪、交易信息分析为一体的系统,收集了13587个有效的比特币地址,成功对其中247个活跃的比特币地址交易进行了监视,并通过启发式方法获得了交易列表,最后结合明网获取相关关联信息,得到了35个较为准确的交易信息表。

The darknet refers to a special network that requires specific configurations to access.Anonymity is the prominent characteristic of dark web communication,which has led to a proliferation of illegal transactions using encrypted digital currency that are difficult to trace.This paper proposes a trackable method for encrypted digital currencies represented by Bitcoin for the latest version of the darknet,Darknet 3.0.Based on our method,a system was designed that integrates dark web page crawling,page information classification,Bitcoin address extraction,Bitcoin address tracking,and transaction information analysis.A total of 13587 valid Bitcoin addresses were collected,and 247 active Bitcoin addresses were successfully monitored for their transactions.A transaction list was obtained through heuristic methods,and 35 relatively accurate transaction information tables were obtained by combining relevant information from the surface web.
