The present invention relates to a message authentication method using a one time incoming number. The message authentication method using a one time incoming number, wherein the method is implemented by a server linked with a user terminal and a message server, comprises: checking a user phone number assigned to the communications terminal of a user; selecting a one time incoming number, which is used only to receive messages transmitted from the user′s communications terminal, from a plurality of phone numbers actually assigned to enable individual line connection to the message server or to the server, or checking a pre-selected one time incoming number; mapping the one time incoming number onto the user phone number and storing the numbers; displaying the one time incoming number as a user dedicated message receiving number on the user terminal checking message reception for the one time incoming number within a predetermined time out by being linked with the message server; checking the outgoing number of a received message when the message reception is confirmed; checking a user phone number onto which the message receiving one time incoming number is mapped, comparing the checked outgoing number with the user phone number, and authenticating whether these two numbers match; determining that the user is authenticated if the user phone number matches the outgoing number; and retrieving the one time incoming number mapped onto the user phone number for message authentication using the communications terminal of another user. |
