A data processing system comprising: a memory having stored thereon a shipment location tracking and security utility (SLTSU); a display device that visually presents at least one graphical user interface generated by the SLTSU; at least one network interface device that enables the data processing system to receive and transmit information via one or more communication networks; at least one processor coupled to the memory, the display device, and the at least one NID, and which executes the SLTSU to configure the data processing system to: receive, via the at least one NID, a plurality of location tracking signals indicating a location of multiple shipment-related entities that are being tracked concurrently as a shipment group; associate the location tracking signals as the shipment group and assigning a unique shipment tracking identifier (STID) to the shipment group to track movement of the location tracking signals relative to each other; present, on the display device, the shipment group as a plurality of co-located visual affordances on a shipment tracking user interface, wherein each received location tracking signal is represented by one visual affordance from among the plurality of co-located visual affordances; present, on the display device within the shipment tracking UI, movement of the plurality of location tracking signals associated with the shipment group; monitor, by analyzing the movement of the plurality of location tracking signals of the shipment group, to detect any unscheduled deviations in at least one of an expected co-location and an expected geo-location of received updates to the location tracking signals within the shipment group; and in response to detecting an unscheduled deviation: identify a specific type of the unscheduled deviation; and trigger a series of responsive actions based on the specific type of the unscheduled deviation, the responsive actions comprising presenting at least one of an audible and a visible alert notification. a memory having stored thereon a shipment location tracking and security utility (SLTSU);
