One or more data structures are received by a computing device, wherein the one or more data structures include at least one or more user credentials. The one or more user credentials are normalized by the computing device to generate a first graph. One or more nodes of the first graph and one or more nodes of at least a second graph are analyzed by the computing device, wherein analyzing includes at least identifying a logical correlation between the one or more nodes of the first graph and the one or more nodes of at least the second graph. A third graph is generated by the computing device based, at least in part, upon the analysis of the one or more nodes of the first graph and the one or more nodes of at least the second graph. An output data structure is generated by the computing device based, at least in part, upon the third graph.
