Development of keyless biometric authenticated vehicles ignition system

Abstract

The vehicles are started or ignited using manual keys or sensor based keys. In two wheelers after placing keys the bike is started using either button or kicking method. The other vehicles are started using key cranking or key is placed in specific sensor control area and start button is pressed. The existing method makes any one can able to operate the vehicle if they have keys. The proposed method used to operate the vehicles only they are authorized. The authorization key is available in the controller memory. The proposed method uses dactylogram scanner to access the vehicles. The scanner scans the finger, if the person is authenticated immediately it allows the person to start the vehicles. The controller is attached with the relay electronic board which controls the ignition part. The proposed method uses ATMEGA 162. The device is able to access the vehicle by 3 persons. Only the specific 3 person finger prints are enrolled in the controller. The system is enabled with GSM access. If unauthenticated person access the finger print scanner, the vehicle is not ignited. The GSM module communicates the unauthenticated access attempt to the owner of the vehicles in the form of SMS. If the device is accessed with authenticated person and the vehicle is successfully started. In the meantime unauthorized person starts access with scanner, immediately message was received in the stored GSM mobile number. The average authentication time to start the vehicle is 3.81 s.
