This paper presents investigations of vocal biometric person authentication over the Internet both at the protocol and authentication robustness levels. As part of this study an appropriate client-server architecture for biometrics on the Internet is proposed and implemented. It is shown that the transmission of raw biometric data in this application is likely to result in unacceptably long delays in the process. On the other hand by using data models or features the transmission time can be reduced to an acceptable level. The use of encryption decryption for enhancing the data security in the proposed client-server link and its
