METHOD AND APPARATUS FOR AUTHENTICATING ELECTRONIC COMMUNICATION
First Claim
1. A method of authenticating an electronic communication, the method including:
- parsing a header of the electronic communication to identify actual domain name data included in the header at a server receiving the electronic communication from a communication client;
parsing the header to obtain purported sender data included in the header of the electronic communication;
comparing the actual domain name data and purported sender data; and
generating in response to the comparison an authenticity indicator, to provide a recipient of the electronic communication with an indication of the likelihood that the electronic communication was sent from a purported sender of the electronic communication.
