Abstract: Automatic Toll Collection Using Optical Code Recognition and Encryption provides an alternative to the current existing toll collections techniques and tries to overcome the drawbacks of these system. In this system, the number plate of a particular vehicle is encrypted using DES algorithm and an OCR code is generated out of it. This code is used as sticker on the car windshield. High Definition (HD) cameras capture this code and image processing is performed using Open CV functions on the code. It is then matched in the database. If matched, the tax is debited from the users account and the vehicle is allowed to pass within seconds. If the balance is insufficient then only once pass is allowed. After that the payment has to be made manually. An additional feature that supports this system is that if a vehicle is stolen and an entry is being made in the central database for the same by the police then if the vehicle passes through the toll plaza, a silent alarm would buzz which would indicate the operator at the toll booth that the vehicle is a stolen vehicle.
