Grading based identity negotiation in P2P Services

The increasing popularity of P2P IP Services introduces a new challenge with respect to the identity of users as the lack of incremental tariff on these services removes the incentive to properly identify users before allowing them to register. We analyze multiple scenarios in future networks to demonstrate problems arising out of self assigned user identities in P2P services, and in particular P2P VoIP services. Our analysis establishes the need for a simple mechanism of negotiating `grade of identity´ as an important tool for successful adoption of such services.
