Traditional car security systems face significant vulnerabilities—physical keys can be lost or copied, while keyless entry systems are prone to relay attacks. Many drivers also find carrying keys inconvenient. One way to address these issues could be through biometric authentication, using fingerprint recognition to unlock and operate vehicles.

How It Could Work

The system might integrate fingerprint scanners into door handles for entry and start buttons for ignition. Backup methods like PIN pads or smartphone apps could ensure access when biometrics fail. Additional features could include:

• Personalized driver profiles (seat position, climate settings)
• Multi-user support for shared vehicles
• Encryption and anti-spoofing measures to prevent fake fingerprints

Implementation could range from factory-installed options by automakers to aftermarket kits for existing vehicles or smartphone-based authentication.

Potential Benefits and Stakeholders

This approach could appeal to car owners seeking better security and convenience, fleet managers needing access control, and car-sharing services requiring keyless management. People with disabilities or parents managing teen driving access might also benefit. Automakers could differentiate their products, while insurance companies might offer discounts for enhanced security features.

Execution Considerations

A simpler version could start with aftermarket door handles featuring fingerprint sensors, integrated with a car's existing locking system. Testing might begin with fleet vehicles to evaluate reliability in different weather conditions. For broader adoption, partnerships with automakers could enable factory integration, with more robust sensors that work with gloves or wet fingers. Addressing security concerns would require measures like ultra-wideband technology to prevent relay attacks.

While challenges like sensor durability in harsh weather or user acceptance of biometrics exist, combining multiple authentication methods could provide flexibility. The system could offer a balance between the convenience of keyless entry and the security of active authentication.
