Abstract: Money laundering activities have evolved from a traditional model of Underground Bank to the new model such as "Fourth-Party Payment", along with the rising of the emerging digital currency, which has brought huge challenges to crime investigations, and also caused damage to the social financial system. In view of lack of supervision on the application installation of the digital currency system, lack of supervision on the digital currency transactions, as well as the anonymity of digital currency transactions, we put forward the key channels to solve the problems. This article describes the realization of obtaining real-name of digital wallet addresses, identifying digital exchange addresses, and how to establish evidence of digital currency transactions. In order to figure out the data visualization and address tagging display in the process of digital currency trading, provide clear flow tracking graphics of digital currency trading process for staff in case handling, identify the digital currency exchange, determine if it is able to retrieve evidence from that digital currency exchange, which will significantly improve work efficiency on money laundering crime investigation.

Key words: digital currency, money laundering, wallet address, digital currency exchange, anonymity, evidence retrieval

摘要: 洗钱活动从传统的地下钱庄模式演化为第四方支付模式,以及当前兴起的数字货币模式,给侦查办案带来了巨大的挑战,也给社会金融体系产生了破坏.针对当前数字货币软件应用安装缺乏监管,数据货币交易缺乏监管,以及数据货币交易匿名性等问题,提出解决问题的关键渠道.分别从个人钱包地址实名化标签实现、数据货币交易所地址实名化标签实现、建立交易所电子数据调证通道等角度进行描述.最终实现数字货币交易过程数据可视化和地址标签化展示,为工作人员在办案中提供数据货币交易过程的清晰流向追踪图形,展示哪个节点是交易所,是否调证,以及哪个节点是可以查询实名的钱包地址,从而有效地提高工作效率。
