Abstract: A method for authentication data transmission and a system thereof are provided. The method is operated in a computer system that is connected to a biometric device, and a secure channel is established there-between according to a security protocol. The computer system can receive encrypted biometric feature data from the biometric device based on a request. In a secure environment built in the computer system, the biometric feature data is decrypted and biometric features can be extracted. A comparison result is generated after comparing the biometric features with feature data in a database. The comparison result can be transmitted to the biometric device. The comparison result is then encrypted in the biometric device according to the security protocol. The biometric device can therefore transmit the encrypted comparison result to the computer system via the secure channel.
