Method and system for associating a license plate number with a user

A computer system for determining an association between a vehicle identifier and a user identifier, comprising:

• a processor;
• and
• a non-transitory computer-readable memory storing instructions executable by the processor for:
• obtaining, by the processor, a first plurality of identification events comprising respective identifiers of a first type of identifier and a second plurality of identification events comprising respective identifiers of a second type of identifier different from the first type, the first type and second type of identifier selected from amongst vehicle identifiers and user identifiers, wherein identification events of the first plurality and of the second plurality of identification events occur at different moments in time;
• for a particular identifier being of the first type of identifier, determining, by the processor and from the first plurality of identification events, a set of first type identification events associated therewith, the set of first type identification events comprising a plurality of first type identification events each comprising the particular identifier;
• determining, by the processor, for each first type identification event of the set of first type identification events, a respective set of second type identification events from the second plurality of identification events based on occurrence of the second type identification events within a respective time window associated with each first type identification event, each second type identification event within a given set of second type identification events comprising a respective different second type identifier;
• identifying, by the processor, a correspondence of a number of second type identification events from multiple of the sets of second type identification events, each comprising a same particular second type identifier, with respective first type identification events from the set of first type identification events and matching the particular second type identifier with the particular identifier of the first type of identifier based on said correspondence;
• and
• outputting, by the processor and via a graphical user interface (GUI) displayed on a display device, an indication that the particular second type identifier is a match for the particular identifier of the first type of identifier for presentation on the GUI.
