基于多域情报驱动的虚拟货币犯罪资金流链上溯源研究OACHSSCD

[Purpose]The decentralized anonymous trading of virtual currencies has become the internal driving mechanism for criminal gangs to turn their criminal income onto the chain for circulation from"black to white".In this regard,it is necessary to integrate investi-gation resources by leveraging the ubiquitous cross-domain intelligence information of the digital society to solve the tracking problems such as the complex circulation paths,multiple transaction outlets,and inflow into the"black box"of transactions of the involved virtual currencies.[Method]In the face of the multiple logics of criminal gangs using cross-chain,mixed-coin,and smart contract technologies to divide the involved funds,it is necessary to bypass the fund ports that are concealed and controlled by anti-tracking technologies.Based on the occurrence links of chain crimes such as traffic diversion,communication,and networks,the personnel information and involved as-sets in anonymous transactions can be precisely located through the mutual complementarity and cross-verification of fund data and non-fund data.[Result/Conclusion]In practical tracking,multi-domain intelligence should be utilized to conduct"aggregation"and"chain formation"analysis of involved addresses.By enhancing the stickiness of embedding criminal behavior patterns into the capital flow rela-tionship graph,the matching degree and information value-added space between transaction addresses and criminal intelligence should be strengthened,and the matching and locking of on-chain address accounts with off-chain real identities should be completed.
