A VoIP Privacy Mechanism and its Application in VoIP Peering for Voice Service Provider Topology and Identity Hiding

TL;DR

This paper introduces a unified privacy mechanism for VoIP that protects both users and service providers during peering, with a case study demonstrating its application in hiding identity and topology.

Contribution

It extends existing VoIP privacy solutions to include service provider privacy and demonstrates its practical use in VoIP peering scenarios.

Findings

Proposes a unified privacy mechanism for VoIP providers and users.

Shows how VSPs can hide identity and topology in peering.

Provides a case study illustrating the mechanism's application.

Abstract

Voice Service Providers (VSPs) participating in VoIP peering frequently want to withhold their identity and related privacy-sensitive information from other parties during the VoIP communication. A number of existing documents on VoIP privacy exist, but most of them focus on end user privacy. By summarizing and extending existing work, we present a unified privacy mechanism for both VoIP users and service providers. We also show a case study on how VSPs can use this mechanism for identity and topology hiding in VoIP peering.
