SYSTEM FOR AUTHENTICATION A RECIPIENT BASED AUTHENTICATION CONTENTS

摘要

Disclosed is an authentication system capable of recipient authentication. The system includes: a sending terminal which sends a signal requesting a call; a receiving terminal which receives the signal from the sending terminal; and an authentication server which authenticates if the receiving terminal is a valid recipient (called as recipient authentication). When the receiving terminal receives the signal from the sending terminal, the receiving terminal sends a calling attempt notification that the sending terminal is trying to make a call to the receiving terminal to the authentication server. The sending terminal sends the signal and requests the authentication server to authenticate if the receiving terminal is a valid recipient. The authentication server performs authentication.
