Absolutely. In order to have that happen, the proxy person, or whoever, would have to physically be in the residence in order to have the IP address that it is sent from and known ahead of time to be received from. That validates, at least from a physical perspective, that where that IP address is located is at their home. Then you would have them confirm via a phone call, using their own voice, within a specific window of time. You know their phone number. Their number can't theoretically be spoofed. That's illegal, I would assume, in Canada as it is in the U.S. So, you not only have voice, phone number and specific IP address, you can add in other identifiers that are specific and unique.
