In this paper, we developed speaker verification system for m-commerce (mobile commerce) via wireless internet and WAP. We implemented the system as client-server architecture. The clients are mobile phone simulator and PDA. As the needs for wireless Internet service is increasing, the needs for secure m-commerce is also increasing. Conventional security technique are reinforced by biometric security technique. This paper utilized the voice as biometric security techniques. The verification results are obtained by integrating the mVprotek system with SK Telecom's CDMA system. Utilizing F-Ratio and Virtual cohort model normalization showed much better performance than conventional background model normalization technique.
