Risk control method and device for transfer transaction

The invention provides a transfer transaction risk control method and device, which are applied to the technical field of finance, and the method comprises the steps: constructing a customer association graph, each node of the customer association graph is a customer of a bank, each edge of the customer association graph corresponds to a correlation coefficient, and each correlation coefficient corresponds to the customer of the bank; the correlation coefficient represents the correlation degree of the two customers corresponding to the edge, and the value of the correlation coefficient is between 0 and 1; when the customer transfers the account, determining an association coefficient corresponding to the account transfer according to the customer association graph; according to the correlation coefficient corresponding to the current transfer, determining a first function relationship between a transfer threshold and a risk probability corresponding to the current transfer and a second function relationship
