Abstract

The embodiment of the invention provides a suspicious transaction account identification method and a device, a storage medium and a server. The method comprises the steps of determining an associatedaccount matched with a determined suspicious transaction account according to a fund relationship chain of the determined suspicious transaction account; calculating a role distance score between theassociated account and a plurality of different suspicious transaction member roles according to at least two parameter proportion values corresponding to the plurality of different suspicious transaction member roles; and according to the plurality of role distance scores, identifying whether the associated account is a suspicious transaction account. According to the method of the invention, the suspicious transaction account is identified through the calculated role distance score, so that the accuracy of identifying the suspicious transaction account is improved.
