Authentication of vehicles in preparation for V2V communication includes vehicle A taking a picture of vehicle B and vehicle B taking a picture of vehicle A, and sending that picture to vehicle A. Vehicle A determines the relative location of vehicle B indicated in either picture. If they agree, then vehicle B is authenticated, using a method such as Diffie-Hellman key exchange. The relative location of either vehicle may be measured by determining the distance and angle from one vehicle to the other. The vehicles may be identified in the pictures using their number plates, and the vehicles exchange license plate numbers prior to taking the pictures. Image spoofing may be prevented by taking both forward and rearward facing pictures by both vehicles. Objects in pictures facing the same direction may be identified to verify that the pictures were taken nearly simultaneously.
