Patent ID: 8639922

Claim:
A security system comprising: an input/output device connected to an in-band communications device in an in-band channel network for receiving at the input/output device an instruction to accept or deny a request for a location certificate to verify that at least one in-band request for an action or a transaction received at an application server was initiated by a human operator from a pre-designated location authorized to make the request to the application server via the in-band communications device; at least one electric power meter associated with the pre-designated location for receiving the accepted request and transmitting the same over at least one electrical power conductor line of an electric power distribution network, wherein the at least one conductor line is used as an out-of-band communications channel network that is separate from the in-band communication channel network; and wherein the input/output device outputs information about an event indicating information about (i) attempts that are or have been made to tamper with the input/output device or (ii) whether the input/output device has been successfully tampered with, as soon as one or both events are detected, during a pre-determined monitoring period, or when the input/output device performs a forensic audit.
