Abstract: A computer-implemented method (CIM) that includes receiving an image including a QR code and an area surrounding the QR code, visually inspecting the image of the QR code and the surrounding area, determining whether the QR code and the surrounding area include at least one indication of tampering, and alerting a user of the mobile device to physically check the QR code, if at least one indication of tampering is determined.

Abstract: Tracking movement of a lead vehicle and following vehicles driving to a common destination to maintain a specific relationship of the lead vehicle with the following vehicle(s) traveling through traffic conditions or obstacles such as traffic lights, intersections with stop signs, merging onto other roads, and other traffic obstacles such as road construction on the route to the common destination. The specific relationship is maintained by using data regarding the following vehicles of: real-time speed of the following vehicle, the following vehicle's current location, distance from the following vehicle to the lead vehicles, presence of other vehicles between the lead vehicle and following vehicle, and presence of other vehicles in adjacent lanes to the following vehicle.
