Abstract: A method, computer program product, and computing system for performing an assessment of initial input information, concerning a communication from a caller, to define an initial fraud-threat-level; if the initial fraud-threat-level is below a defined threat threshold, providing the communication to a recipient so that a conversation may occur between the recipient and the caller; performing an assessment of subsequent input information, concerning the conversation, to define a subsequent fraud-threat-level; and effectuating a targeted response based, at least in part, upon the subsequent fraud-threat-level, wherein the targeted response is intended to refine the subsequent fraud-threat-level.

Abstract: Proxy accounting for a home agent is implemented. Packets are monitored on a home network. A registration request sent from a mobile node connected to a foreign network to a home agent residing on the home network is detected among the packets, corresponding to a registration sought by the mobile node on the foreign network. A registration reply sent from the home agent to the mobile node is detected among the packets, indicating that the home agent approves the registration. It is determined that the registration is new. An accounting-start indication is caused to be recorded for the registration. A registration-termination request sent to the home agent is detected among the packets, seeking termination of the registration. A registration-termination reply sent from the home agent is detected among the packets, acknowledging termination of the registration. An accounting-stop indication is caused to be recorded for the registration.
