摘要

The present invention relates to a technique for authenticating a user by using junk data which is randomly generated by a random key when a password is input. According to the present invention, the password is received from the user and stored, and user authentication can be successfully processed when the password matched to an original password stored in a memory exists among the junk data and the password which are input together in a user authentication step. Security can be enhanced by processing authentication only when the junk data is not matched to the junk data which is input by the user and stored in the memory in the previous authentication process.;COPYRIGHT KIPO 2017
