Technical Field

The invention provides a method for analyzing block chain asset transaction risk, and belongs to the technical field of network payment.

Background

A blockchain asset is a digital encryption asset based on a peer-to-peer network and encryption algorithms. The core features of a blockchain asset are mainly embodied in three aspects: (1) since blockchain assets have no issuing agent from some open algorithm, no one or organization can control its issuance; (2) the total amount of the block chain assets is fixed due to the fact that the number of the algorithm solutions is determined, and therefore the possibility of expansion of the currency caused by the block chain assets being abused is fundamentally eliminated; (3) since the transaction process requires approval by various nodes in the network, the transaction of the blockchain asset cannot be altered once completed. The transaction of the blockchain assets is disclosed in the blockchain account book, and any operating blockchain node can acquire the disclosed blockchain account book through the peer-to-peer network.

The transaction of the blockchain assets is usually carried out between two or more digital wallets, the digital wallets have the characteristics of no need of registration, unlimited quantity creation, anonymity and the like, criminals and malicious attackers often utilize the characteristics of the digital wallets to carry out frequent and deep splitting, transferring and cleaning on illegally obtained blockchain assets, then common traders are searched from the open market, and the cleaned illegal blockchain assets are transferred to the digital wallets of other people.

Disclosure of Invention

The method for analyzing the risk of the block chain asset transaction provided by the invention has a simple structure and can solve the problem of unsafe asset transaction.

In order to solve the above problems, the present invention provides the following technical solutions: a method for analyzing block chain asset transaction risk comprises an illegal asset control wallet address acquisition module, a block chain asset transaction risk studying and judging module and an illegal asset transfer link monitoring module, and the main operation method comprises the following steps:

the illegal asset control wallet address acquisition module is mainly used for acquiring and extracting abnormal digital wallets related to the block chain assets from various social platforms, media information platforms and personal blog platforms on the Internet through a text crawler program and constructing an abnormal digital wallet database;

the block chain asset transaction risk studying and judging module extracts the characteristics of historical transaction times, historical transaction time, historical transaction amount and the like of digital wallets of both parties of the abnormal transaction by relying on an abnormal digital wallet database, extracts abnormal block chain asset transaction contents from a block chain account book, and trains an abnormal block chain asset transaction characteristic model by utilizing data statistics, mathematical modeling and artificial intelligence technologies;

the illegal asset transfer link monitoring module is mainly responsible for monitoring the asset transfer behavior of the illegal asset control wallet address in real time, intelligently identifying and marking whether the receiving address is an abnormal digital wallet or not by combining the risk studying and judging module, and continuously importing the abnormal digital wallet into the abnormal digital wallet database.

The invention has the beneficial effects that: the invention designs a set of system to analyze the transaction risk of the blockchain asset, performs characteristic analysis and mathematical modeling on the known risky blockchain asset transaction through transaction book data disclosed by the blockchain and threat information data disclosed on the Internet, outputs an analysis pre-judgment model of the blockchain asset risk transaction, provides safety guarantee for the blockchain asset transaction, constructs a set of risk filtering function for the blockchain asset transaction process, blocks abnormal risk transaction in advance, and avoids the invasion of illegal assets.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

According to the illustration of FIG. 1: the invention provides a method for analyzing block chain asset transaction risk, which comprises the following steps: the system comprises an illegal asset control wallet address acquisition module, a block chain asset transaction risk study and judgment module and an illegal asset transfer link monitoring module, and the main operation method comprises the following steps that the illegal asset control wallet address acquisition module acquires and extracts abnormal digital wallets related to block chain assets from various social platforms, media information platforms and personal blog platforms on the Internet mainly through a text crawler program, and an abnormal digital wallet database is constructed; the block chain asset transaction risk studying and judging module extracts the characteristics of historical transaction times, historical transaction time, historical transaction amount and the like of digital wallets of both parties of the abnormal transaction by relying on an abnormal digital wallet database, extracts abnormal block chain asset transaction contents from a block chain account book, and trains an abnormal block chain asset transaction characteristic model by utilizing data statistics, mathematical modeling and artificial intelligence technologies; the illegal asset transfer link monitoring module is mainly responsible for monitoring the asset transfer behavior of the illegal asset control wallet address in real time, intelligently identifying and marking whether the receiving address is an abnormal digital wallet or not by combining the risk studying and judging module, and continuously importing the abnormal digital wallet into the abnormal digital wallet database.

Principle of the invention

The illegal asset control wallet address acquisition module can continuously and dynamically provide an input information source for a crawler program by depending on a keyword extraction technology and a natural language processing technology, the acquisition module can cover malicious behaviors of illegal acquisition block chain assets such as asset theft, phishing fraud, expense transfer fraud, money rolling running and the like, when the block chain asset transaction risk research and judgment module is used subsequently, the module can be loaded to intelligently analyze and judge whether digital wallets of two transaction parties are abnormal or not, the illegal asset transfer link monitoring module is mainly responsible for monitoring the asset transfer behavior of illegal asset control wallet addresses in real time, and is combined with the risk research and judgment module to intelligently identify and mark whether receiving addresses are abnormal digital wallets or not, and the illegal asset control wallet addresses are continuously led into an abnormal digital wallet database. The invention has simple structure and can solve the problem of unsafe asset transaction.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
