<p>According to a method for generating a one time password (OPT) of the present invention, a method executed through an IC chip generating an OTP comprises: storing a static seed value to dynamically generate an OTP having N (N>=2) digits inside an IC chip and storing body authentication information to authenticate the body of a user inside the IC chip; receiving biometric information of the user, which is composed of a structure to be authenticated inside the IC chip through the body authentication information; authenticating the effectiveness of the biometric information by using the body authentication information; confirming a dynamic seed value to dynamically generate an OTP having N digits when the effectiveness of the biometric information is authenticated; dynamically generating the OTP having N digits by using the static seed value and the dynamic seed value as a seed value of a code generating algorithm set inside the IC chip.</p> |
