Abstract

The invention relates to a multi-standard collaborative fraud detection method based on credit accumulation, and is used for discovering collaborative fraud organizations and identifying the members thereof. The method comprises the following steps that 1) a single suspicious user node is detected and marked in a social network, and the set of all the suspicious user nodes is acquired by using a credit accumulation model; 2) the suspicious relation of the suspicious users in the set delta is judged, and the collaborative fraud organization models to which all the suspicious users belong in the set delta are classified; and 3) the organizers in the classified collaborative fraud organization models are monitored and identified. Compared with the methods in the prior art, the multi-standard collaborative fraud detection method based on credit accumulation has the advantages of being wide in detection objects, advanced in algorithm and comprehensive in assessment.
