METHOD FOR PROVIDING MULTI-CHANNEL AUTHENTICATION BY USING ONE TIME CODE

摘要

The present invention relates to a method for providing a multi-channel authentication by using one time code. The method for providing a multi-channel authentication by using one time code according to the present invention is capable of communicating with a user terminal through a first channel, and provides a multi-channel authentication by using one time code executed by a server communicating with the user terminal through an extra second channel which is different from the first channel. The method comprises the steps of: a first step of receiving authentication request information requesting a multi-channel authentication through a designated route including a first channel; a second step of checking a user′s wireless terminal capable of communication through the second channel based on the authentication request information; a third step of receiving the one time code dynamically produced by the user′s wireless terminal through the second channel; a fourth step of checking the authentication result of the one time code; and a fifth step of providing the authentication result through the designated route.
