Generally, theft of many vehicles is taken place mainly in big cities. Now-a-days not only motor bikes, the big vehicles like cars, Lorries and trucks are also theft by the criminals. This is due to the lack of the security provision for the vehicles. The manual mechanical key based lock is the main drawback in the present vehicle systems. If somebody stolen the vehicle key can easily start the engine of the vehicle.
To protect our vehicles from theft, the present mechanical key based security system should be replaced with biometric fingerprint based ignition lock system. The entire circuit of this project provides an anti-theft device for vehicles. The technology used in this device is based on biometrics and embedded systems.
In this project, the biometric fingerprint based key system is accessed only by the authorized person or owner of the vehicle otherwise the vehicle won’t be start. If any authorized person tries to start the vehicle an alarm will be activated or a SMS is sent to the police and owner of the vehicle.
Technology involved in this project, is biometric fingerprint based authentication system. The fingerprint scanner module SM630 is used to scan the fingerprint of the authorized persons. The authorization of a person is verified by the 8051 program which is written in embedded C and burns it into the 89S52 microcontroller flash memory. A GSM modem (dual band GSM (900/1800) messaging system) is interfacing to 89S52 microcontroller to provide the SMS alerts when the unauthorized persons try to access the vehicle ignition lock.
