Embodiment Construction

[0031] The core of the present invention is to provide a dynamic financial network monitoring and analysis method. The method first establishes a dynamic financial network model based on the financial database, and calculates the attribute weights according to the suspicious transaction case database, and then analyzes the accounts and transactions in the financial network. Suspiciousness is dynamically monitored and analyzed. Finally, when new suspicious transactions appear, the attribute weights are updated; when new financial transaction data appears, the dynamic financial network model is incrementally updated.

[0032] The flow chart of the inventive method is as figure 1 shown. Note that step 4 and step 5 are a process of constantly monitoring data, as long as there is new suspicious transaction data or new financial transaction data, step 4 and step 5 will be executed. In practice, the implementation of this method will not end unless no new transaction data will ever ...

Abstract

The invention discloses a dynamic financial network monitoring analytical method, comprising the following steps especially: (1) building a dynamic financial network model, the flowing conversion process from a financial database to a directional weighted graph is included; (2) computing weight of attribute: by analyzing case database of doubtful transaction, doubtful degree weight of the attribute is obtained by statistical leaning, the weight of attribute is for short; (3) dynamically monitoring analysis of the doubtful degree of account and transaction is carried out; by comprehensively considering the common effect of multiple attributes of account and transaction, and the effect of the last time slice on the current time slice, the doubtful degree of account and transaction along with time is dynamically monitored; (4) updating the weight of attribute: when a new doubtful transaction appears, the case database of doubtful transaction and the weight of attribute are updated; (5) incremental updating the dynamic financial network model: when a new data of financial transaction appears, the financial database and the dynamic financial network model are updated.

Description

technical field [0001] The invention belongs to the field of financial informatization, and in particular relates to a dynamic financial network monitoring and analysis method. Background technique [0002] With the continuous improvement of my country's informatization and internationalization, financial crimes such as credit card fraud, e-commerce crimes, money laundering and other crimes are becoming more and more rampant. The means by which criminals carry out their crimes are diverse, and they are easily overwhelmed by the large number of financial transactions every day, making it almost impossible to manually detect these crimes. [0003] Internationally, there are many researches on anti-money laundering monitoring and analysis through information technology, and many countries have established financial intelligence agencies one after another. The country also attaches great importance to combating money laundering crimes. On April 7, 2004, a special agency for col...
