The Session Initiation Protocol (SIP) is the main protocol behind Voice over IP (VoIP). However, it does not provide authentication, which may lead to possible impersonation and eavesdropping threats. Negotiating keys using digital certificates may help secure the channel, but this method incurs extra maintenance cost. Verbal authentication utilizes the real-time nature of VoIP but it requires users to read and manually compare the authentication code. This paper proposes a session identifier framework based on the Modified Vector Quantization (MVQ) method on real-time video frames for video communication in VoIP.
