Abstract

A resource transfer information detection method and apparatus are provided. In a process of performing resource transfer path search on a resource transfer relationship graph, a current search node, a reference node that points to the current search node and that is in a current resource transfer path, and a candidate node that the current search node points to and that is in the resource transfer relationship graph are determined. A first resource transfer time is obtained between the current search node and the reference node and a second resource transfer time between the current search node and the candidate node is obtained. When the first resource transfer time and the second resource transfer time satisfy a time difference condition, the candidate node is added to the current resource transfer path to detect a target resource transfer path.
