❱ ❱ Other biometrics such as eye gaze and second order biometrics such as cognitive load could help in determining handover capability for autonomous vehicles

❱ ❱ Fingertip control requires multi-spectral biometric fingerprint sensor for reliable operation

For car security, the population is unknown and the consequences of false acceptance are unacceptable so the system needs to be tuned for higher security, which has the potential to provide a poor user experience caused by frequent false rejections.

FINGERTIP CONTROL AT HYUNDAI Hyundai has introduced smart fingerprint technology into its Santa Fe model that is to be released in select markets in the first quarter of 2019. To unlock the vehicle, the driver needs to place a finger on the sensor located on the door handle. The encrypted fingerprint information will be identified and delivered to the fingerprint controller inside the vehicle. The driver can also easily start the vehicle by touching the ignition that is also equipped with a fingerprint scanning sensor. Matching information of driver

preference with fingerprint data, the vehicle automatically adjusts seating positions, connected car features and side-view mirror angles according to the identified driver. Using state-of-the-art capacitance based recognition technology, which detects differentials in the electricity level in various parts of the finger tip,

the fingerprint technology efficiently prevents forgeries and faked fingerprints. The technology’s chance of false acceptance is 1 in 50,000 making it five times more effective than conventional vehicle keys, including smart keys. Moreover, through real-time learning of fingerprints supported by a dynamic update system, the fingerprint system can continually improve its success rate.

TOOL OR TOY Consumer electronics biometrics always have backup access facilities. If you can’t access your smartphone with your fingertip after five attempts, you’re asked to enter your PIN – a practice that completely destroys the security advantage of using biometrics and thus reduces it to gimmickry. The provision of backup access through passwords, PINs, smart cards or keys has prevented biometrics from becoming mainstream and has kept it in the domain of recognition and detection applications. It’s yet to be seen whether the new Santa Fe will be supplied with a backup set of keys but Hyundai’s step into biometric car control is nonetheless a step forward in vehicle security and one that will ultimately result in completely keyless vehicle access.


reating conditional autonomous cars, often referred to as Level 3

autonomous cars, is the next logical step in future mobility progression. These have the ability to manage most aspects of driving by themselves, but only if certain conditions are met and if not, they would require the human to take over. The biggest challenge with these vehicles is managing the hand-over: the situation where the car must transfer control back to the driver once limitations are met. In order to ensure this happens seamlessly, Harman has developed an advanced Cabin Monitoring System which uses monitoring sensors to capture the most important first-order biometric features of a driver, such as eye gaze, head position, and pupil diameter among others. The system can also analyse the auditory content and heart or breathing rates of occupants using proprietary and patented algorithms to provide second-order biometric signals such as emotional activity and cognitive load. While capable of working in lower levels of autonomy, this system will be critical to the success of semi- autonomous vehicles in the future.
