Beijing Didi Wuxian Technology Development Co., Ltd., an affiliate of Didi Chuxing, recently disclosed the patent for "Fraud Detection Method and Device". This invention can obtain order information of successful transactions within a preset time period; it can be obtained based on the order information. Terminal groups with the same order-issuing UE are obtained, and the number of terminals in the terminal group and the number of terminal groups with the same order-issuing UE are obtained.
If the number of terminal groups with the same order-issuing UE is greater than the preset threshold corresponding to the number of terminals, it is determined that the UE group formed by the terminal group and the corresponding same-order UE is cheating. Groups were formed and penalties were imposed, thus achieving the purpose of preventing driver groups and passenger groups from collaborating to cheat on orders.
