<p>The present invention relates to an internet security system using one-time identification (OTID), which is capable of providing disposable OTID to a user in the field requiring user authentication, so that the user is no longer required to memorize any ID. An internet security system using OTID according to the present invention includes an OTID application (200) which continuously receives OTID, changed in every preset time, from an OTID management center (100); and the OTID management center (100) for transmitting the continuously changed OTID to the OTID application (200), wherein the OTID management center (100) issues a password to a registered password destination (300) when the ID input through a login display for user authentication is identical to the issued OTID, and approves a log-in when the password input through a login display for user authentication together with an ID is identical to the issued password. In addition, when at least two password destinations (300) are registered, the OTID management center (100) divides the issued password and provides the divided passwords to the at least two password destinations (300), respectively.</p> |
