## Title
Using pass code verification to organize a vehicle caravan

## Abstract

A reference pass code is received from a first user. Location information of a vehicle of the first user is received from a first computer. A pass code is received from a second user. Location information of a vehicle of the second user is received from a second computer. One or more computer processors verify that the pass code received from the second user matches the reference pass code. Based on verification of the pass code received from the second user, the location information of the vehicle of the first user is transmitted to the second computer and the location information of the vehicle of the second user is transmitted to the first computer.

## Background
FIELD OF THE INVENTION
The present invention relates generally to organization of a caravan, and more particularly to the verification of a pass code for the purpose of organizing a caravan.
BACKGROUND
Navigation systems have become more and more sophisticated over the last few years. Prior to the technology boom, it was normal to draw out your desired route on a paper map and keep the map open in the car for reference. However, now GPS (global positioning system) navigation systems are able to determine directions, display your location on a digital display and even suggest alternate routes in case of traffic or an emergency. This has simplified the driving experience and helped drivers stay on course with ease. In addition, some unique navigation systems monitor the locations of their subscribers and, in some cases, even publicize the locations of their subscribers for all other subscribers to see.
SUMMARY
Embodiments of the present invention provide a system, method, and program product for verifying a pass code for the purpose of organizing a caravan. A reference pass code is received from a first user. Location information of a vehicle of the first user is received from a first computer. A pass code is received from a second user. Location information of a vehicle of the second user is received from a second computer. One or more computer processors verify that the pass code received from the second user matches the reference pass code. Based on verification of the pass code received from the second user, the location information of the vehicle of the first user is transmitted to the second computer and the location information of the vehicle of the second user is transmitted to the first computer.

Server 110 is described in more detail with reference to FIG. 3.
Caravan program 112 is a software application capable of receiving a pass code from driver application 122 and/or driver application 132 via network 130 and determining if the received pass code matches a previously stored reference pass code. In the exemplary embodiment, caravan program 112 is also capable of receiving and transmitting location information to computing device 120 and/or computing device 140 via network 130. The operation of caravan program 112 is described in further detail below with reference to FIG. 2.
GPS satellite 150 is a hardware device capable of receiving and transmitting location information to GPS modules such as GPS module 128 and GPS module 118.
FIG. 2 is a flowchart illustrating the operations of caravan program 112 in verifying a pass code in order to determine if a vehicle can join a caravan, in accordance with an exemplary embodiment of the invention. In an exemplary embodiment, caravan program 112 receives a reference pass code from driver application 122 via network 130 and stores the reference pass code in memory (step 202). In the exemplary embodiment, the user of computing device 120 inputs the reference pass code into driver application 122 via user interface 124. Driver application 122 then transmits the reference pass code to caravan program 112 via network 130. In other embodiments, the reference pass code can be received by a user or administrator of server 110 from the user of computing device 120, over the phone or by another means of communication, and then input into caravan program 112 via a user interface by the user or administrator of server 110. Caravan program 112 then saves the reference pass code in memory. In further embodiments, caravan program 112 may use voice recognition software to receive the reference pass code from the user of computing device 120 over the phone or by another means of communication Overall, a pass code may comprise of written components, such as, numbers, symbols, shapes, etc., auditory or visual components or any other communicative expression. In addition, in the exemplary embodiment, when caravan program 112 receives the reference pass code from driver application 122, caravan program 112 begins a caravan with the vehicle of the user of computing device 120 being the first member. In other embodiments, if the user of computing device 120 does not wish to begin the caravan immediately after submitting the reference pass code, caravan program 112 may require the user of computing device 120 to input the pass code, for verification purposes, via driver application 122 at a later time when the user of computing device 120 desires to begin the caravan.
Caravan program 112 then receives a user pass code from driver application 132 via network 130 (step 204). In the exemplary embodiment, the user of computing device 140 inputs the user pass code into driver application 132 via user interface 134. Driver application 132 then transmits the user pass code to caravan program 112 via network 130. As stated above, a pass code may comprise of written components, such as, numbers, symbols, shapes, etc., auditory or visual components or any other communicative expression.
Caravan program 112 then determines if the user pass code received from driver application 132 matches the reference pass code (decision 206). In the exemplary embodiment, caravan program 112 determines if the user pass code matches the reference pass code exactly, however, in other embodiments, caravan program 112 determines if the user pass code matches within a threshold percentage of the reference pass code.
If caravan program 112 determines that the user pass code does not match the reference pass code (decision 206, “NO” branch), caravan program 112 does not allow the vehicle associated with the user of computing device 140 to join the caravan.
If caravan program 112 determines that the user pass code does match the reference pass code (decision 206, “YES” branch), caravan program 112 transmits the location information of the vehicle associated with the user of computing device 140 to the computing devices associated with the other vehicles in the caravan, i.e., computing device 120 (step 208). In the exemplary embodiment, the location information is received by driver application 122 and displayed to the user of computing device 120 via user interface 124. In other embodiments, caravan program 112 may also transmit other information, such as status information, with the location information transmitted to computing device 120. For example, if the vehicle associated with computing device 140 is in an emergency situation or in need of assistance, caravan program 112 transfers this status information of the vehicle associated with computing device 140 to computing device 120.
In addition, if caravan program 112 determines that the user pass code does match the reference pass code (decision 206, “YES” branch), caravan program 112 also transmits the location information of the other vehicles associated with the caravan, i.e., computing device 120, to driver application 132 via network 130 (step 210). As stated above, in other embodiments, caravan program 112 may also transmit other information, such as status information, with the location information transmitted to driver application 132. Furthermore, the same methodology may be applied if additional vehicles desire to join the caravan.
