A method and system for automatically creating a unique driver profile for a vehicle from driving habits. A unique driver profile is created with a portable on-board diagnostic series 2 (OBD-2) apparatus and/or linked and/or standalone network device (e.g., smart phone, tablet, wearable device, etc.). The unique driver profile is created from the accepted plural signals including time and geo-location data based on driving habits of the driver. The unique driver profile information is recorded on the apparatus and/or network device, downloaded at a later time or sent in real-time to check and verify an identity of the driver. The unique driver profile helps confirm an identity of the driver of the vehicle based on unique driving habits of the driver.
