Advanced Biometric Vehicle Access System (SMART-AKK) for Enhanced Security

The SMART-AKK project aims to develop a secure vehicle access system utilizing biometrics and encrypted communication to protect against security vulnerabilities, such as lost/stolen keys and eavesdropping. It features a Tiny Encryption Algorithm for data encryption, an ARA-ME-01 biometric module for fingerprint authentication, and XBee wireless communication over a 10-meter range. The system operates through master fingerprint enrollment, additional fingerprint tracking, and executes commands such as locking/unlocking doors and starting the engine.
