1. A method comprising:
with a computing system in communication with a plurality of detection systems, receiving a plurality of identity tokens detected by the detection systems;
with the computing system, associating each of the plurality of identity tokens with a node of a graph;
incrementing an edge between two nodes of the graph in response to determining that the two identity tokens associated with the two nodes were detected by a first detection system within a detection time window;
decrementing the edge between the two nodes in response to determining that one of the identity tokens associated with one of the two nodes is detected within the detection time window without detecting one of the identity tokens associated with the other of the two nodes; and
correlating the identity tokens associated with the two nodes based on a value of the edge.
