PVN has the ability to authenticate the source of the data transmission it will receive. PVN can inspect incoming data and access information from its source, then the address of the source data will be approved if the authentication process succeeds, so the VPN can guarantee all data sent as well as received from sources that really it should, no information or data sent by the other party and the data being falsified.
