System and Method for Identifying a Change in the Operator of a Vehicle

A system for identifying a change in the operator of a vehicle includes a controller configured to determine, during operation of the vehicle by a current operator of the vehicle over a period of time, a plurality of values for at least two variables associated with the current operator. The controller correlates the values for the two variables to form a plurality of data points which together form a point cloud associated with the current operator. The controller performs a comparison of the point cloud to a point cloud stored in a memory and associated with a prior operator of the vehicle and determines, responsive to the comparison, whether the current operator of the vehicle is the prior operator of the vehicle.
