Peer-to-Peer VoIP (voice over IP) networks, exemplified by Skype, are becoming increasingly popular due to their significant cost advantage and richer call forwarding features than traditional public switched telephone networks. One of the most important features of a VoIP network is privacy (for VoIP clients). Unfortunately, most peer-to-peer VoIP networks neither provide personalization nor guarantee a quantifiable privacy level. In this project a novel flow analysis attacks to demonstrate the vulnerabilities of peer-to-peer VoIP networks and a method to overcome these attacks have been proposed. There are two important challenges in the design privacyaware VoIP networks: Can provide personalized privacy guarantees for VoIP clients that allow them to select privacy requirements on a per-call basis and how to design VoIP protocols to support customizable privacy guaranteed This project can propose a practical solutions to address these challenges using a quantifiable k-anonymity metric and a privacy-aware of VoIP route setup and to route maintenance protocols. A detailed experimental evaluation that demonstrates the performance and scalability of the proposed has been implemented in this paper.
