Smartphone based system for vehicle monitoring security

A non-transitory computer-readable medium having instructions stored thereon, wherein the instructions, when executed by a suitably programmed information-processing system, perform a method comprising:

• acquiring, into a in-vehicle computer, vehicle data that includes vehicle-diagnostic data, time data, and location data associated with a route that a particular vehicle travels;
• associating the vehicle-diagnostic data with the time data and the location data;
• securing the vehicle data while stored on the in-vehicle computer;
• processing said vehicle data according to a mathematical algorithm to generate derived diagnostic and location information that is at least in part derived from the acquired vehicle-diagnostic data, time data, and location data, and wherein the derived information has a meaning distinct from the acquired vehicle data;
• formatting the derived diagnostic information for display on an application running on a host computer device, wherein the application can provide an interface for presenting information associated with the vehicle, wherein the interface includes at least one of an icon and a data field associated with derived information indicative of the vehicle's engine performance;
• and
• wirelessly transmitting said formatted vehicle data in a communication to host computer device.

A data structure for organizing a set of vehicle data regarding a particular vehicle, wherein the set of vehicle data includes vehicle diagnostic data, time data, and location data associated with a route the particular vehicle travels, the data structure including:

• vehicle information derived from the particular vehicle's vehicle identification number (VIN) that indicates a make and model of the particular vehicle but that does not include a serial number of the particular vehicle;
• and
• a plurality of interval subsets, each interval subset associated with a particular interval of travel, and each interval subset including:
• data indicative of a start location for the particular interval,
• data indicative of an end location for the particular interval,
• data indicative of a start time for the particular interval,
• data indicative of an end time for the particular interval, and
• data indicative of a plurality of vehicle diagnostic data associated with the particular vehicle between the start location and the end location for the particular interval.
