There are three ways to enter your car and start the engine, and they are mechanical key-lock system, remote keys system and keyless entry system. However, either way, the driver has to have a key for the car to recognize. At present, for the security design of car keys, encryption with radio communications is most commonly used to prevent brute-force key guessing attack, statistics attack and masquerade attack. The key that a driver carries may be stolen or picked up by someone after it is lost, creating a security breach for theft prevention. In addition, the verification with a driver’s key does not guarantee that the key holder is really the driver. Therefore it is impossible to provide the service of automatic reinstatement of a driver’s preferences.

Biometric identification provides solutions for the above problems. Biometric identification identifies by using the biological features of a driver as the basis of identification, thus reducing the risks of theft or loss of property due to driver’s negligence. In addition, the biometric features of every driver are perfect for driver identification, or even for automatic reinstatement of a driver’s preferences in the future as they are unique to the driver him/herself. So far there are many ways of biometric identification, such as fingerprint, face profile, iris, palm print, voice, vein and multi-pattern identification.

A fingerprint identification keyless entry system consists of PORTABLE TRANSPONDER, ANTENNA MODULE, DOOR HANDLE, DOOR MODULE and CAR PC. Not one can use the portable transponder without passing fingerprint identification. After the driver passes the fingerprint identification, a passive bi-directional communication of the portable transponder is activated. When the driver pulls the door handle, the onboard antenna module send out an LF signal (125 kHz) to the driver’s portable transponder. On the signal, the portable transponder is initiated and starts the security check. After the portable transponder passes the security check, the door module sends a signal to open the door and another to onboard control unit to activate the automatic reinstatement of a driver’s preferences. The portable transponder identifies the current driver by fingerprints and sends out the driver’s ID through wireless communication module for the CAR PC to call out the current driver’s preferences.

Biomsecure offers several solutions to automotive manufacturers in form of integrated modules or remote stand alone modules for keyless entry.
