A Layered Service Provider/Customer Approach to Call Spoofing

We are proposing a layered solution, which leverages the respective capabilities of both the service provider and a customer-managed solution. We will address spoofing and/or authentication of calls for a large number of scenarios. Our solution will reach a large number of users including mobile, government and enterprise. We will provide incremental value to "chip" away at the issue sooner rather than later. They key is to have flexible technologies, both in Verizon's network and present with in the customer/consumer network, that can exchange information in real-time, to both determine if the call is spoofed or authentic. This allows Verizon to provide information about whether or not they think the call is spoofed, merge it with information from the customer, and then let the customer make the actual call control decision. This layered solution is necessary because the customer is unlikely to ever have access to enough information to detect most types of spoofed calls. Conversely, Verizon may not have access to information such as customer lists, white lists and granular rules which control what is done with the spoofing information. Basing the proposal on the existing PolicyGuru solution, we provide a software base to build upon, a system that can be deployed in voice networks and a ready path for commercialization.
