<p>A biometric immobilizer (200) for automobiles, comprising a bio-fingerprint authentication unit (20) including an embedded fingerprint biometrics processing unit (22) and a sensor (24) capable of capturing human fingerprint biometric pattern, and a flash memory (26) able to store biometric data and information, wherein the bio-fingerprint authentication unit (20) having a typical biometrics verification, and an embedded immobilizer controller (30) communicate closely with the bio-fingerprint authentication unit (20) to perform biometric fingerprint enrolment, biometric fingerprint verification operation, and bio-data management, wherein the embedded immobilizer controller (30) establishes a secure communication protocol between the embedded immobilizer controller (30) and the bio-fingerprint authentication unit (20) to prohibit illegal access to the bio-fingerprint authentication unit (20), and generates a secure communication key between the bio-fingerprint authentication unit (20), and the embedded immobilizer controller (30). The biometric immobilizer provides anti-hijacking protection to further protect the driver from anti-hijack while in driving state.</p> |
