VoIP and collaboration Internet applications are a driving force for the use and expansion of the Internet. Current applications usually require end user registration in a central user database, which in turn provides directory services to the users of the relevant system; in addition they use either two bridged client-server connections between the end users and the server or they allow direct client connections. In this paper we propose a new architecture that leverage security for user communications carried over the Internet. Our proposal ensures end-to-end security through the implementation of the biometric based procedures followed by the VoIPSec (Voice Interactive Personalized Security) protocol. Our approach alleviates the need of a trusted third party authentication authority. We present the architecture of a novel application with enhanced security. We also identify implementation fundamentals and provide experimental results for the overhead on the data exchange path and on the end users' devices. © 2007 IEEE.
