Decentralized Vehicle Legitimacy Verification for Toll Gate Using Blockchain

As we know Vehicle registration number plate plays a key role in verifying the identity of a vehicle, it is mandatory and crucial for every Automobile. On the other hand, the existing toll system does not verify the legitimacy of a car whether the number plate is original or a duplicate one. So, this paper aims to propose an innovative solution for this problem that deals with inspecting a number plate while a vehicle passes through the toll gate. We use blockchain technology which stores the transaction of a vehicle after it is proven as the legal one. Our approach follows that while registering the vehicle at the office we provide a unique code and store that unique along with the owner details and we integrate that code in the number plate as RFID, we only do this once while registering afterward it can't be tampered with. When a vehicle passes through toll we scan and retrieve the unique code and verify whether it exists in our database. If it exists, the Vehicle is legitimate. If we can't extract the unique code from the number plate, then it is a duplicate one. If it is legal the transaction will be processed as usual, and the block of transaction will be added to the existing blockchain network. To summarise this paper demonstrates a solution that is reliable, and secure and reduces fraud activities that lead to scandal.
