Problems solved by technology

The method based on transaction association analysis can usually only obtain the relationship between addresses, but cannot directly obtain the user's identity information to achieve the purpose of traceability
Moreover, the accuracy of this method can be significantly affected once users adopt one-time address strategies or transaction obfuscation strategies
[0005] In the digital currency based on blockchain technology, it is difficult to combine the wallet address with the user's identity, which is not conducive to guessing the user's identity information, and it is more difficult to verify the validity and authenticity of the information

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0031] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0032] In one technical solution, the analysis method of multi-channel data fusion includes:

[0033] According to the malicious digital currency address as the seed, the transaction data is crawled from the dark web, and the transaction data includes the transaction address and transaction content;

[0034] Merge the transaction contents of transaction addresses with the same identity;

[0035] Combined with blockchain transaction flow analysis and clear network data analysis, the identity of the transaction address is supplemented with information.

[0036] In the above technic...

Abstract

The invention discloses a multichannel data fusion analysis method. The method comprises the following steps: crawling transaction data from a dark network by taking a malicious digital currency address as a seed, the transaction data comprising a transaction address and transaction content; combining the transaction contents of the transaction addresses with the same identity identifier; and in combination with blockchain transaction flow analysis and open network data analysis, performing information supplementation on the identity identifier of the transaction address. The invention also provides a multichannel data fusion analysis device. According to the invention, association analysis is carried out on the Internet and dark network information, so that the problems of active and passive analysis methods can be effectively solved.

Description

technical field [0001] The invention relates to network content association analysis technology. More specifically, the present invention relates to an analysis method and device for multi-channel data fusion of blockchain-based digital currency in open cyberspace and related hidden environments. Background technique [0002] Bitcoin originated from an article under the pseudonym Satoshi Nakamoto. It is a globally shared distributed and decentralized ledger system. It is one of the most successful applications of blockchain technology at present. Blockchain-based digital currencies emerge in endlessly, and they are highly concealed, making it difficult to effectively manage digital currencies. At present, there are relatively few researches on digital currency management at home and abroad. The existing researches are mainly divided into two categories: active detection and passive analysis. [0003] In terms of active detection, it is mainly the network layer traceability...
