Why Tiny Encryption Algorithm?

AKV Data Packet : 64-bits

AKK/AKV VIN Key : 128-bits(used to encrypt data packet)

Example AKV Data Packet:

Biometric Verification

• Scanning & Matching up to 120 unique fingerprints• 1 Master fingerprint to erase & enroll fingerprints• Enrolled fingerprints are able to control AKV• < 3 seconds fingerprint matching
