SECRET KEY OF PASSWORD GENERATING SYSTEM AND METHOD USING 2 DIMENSIONAL BARCODE

摘要

PURPOSE: A system and method for generating a secret key for a password using a two-dimensional barcode is provided to generate the secret key for the password by mutually combining issued unique two-dimensional bar codes. CONSTITUTION: A secret key generating system for a password using two-dimensional bar codes for user authentication performs financial transaction between a bank server(140) and a user terminal(120). The user terminal receives the password and the two-dimensional bar code for a public key certificate from a user. The user terminal generates the secret key about the password by combining a random number sequence which is obtained from the password and the two-dimensional bar code. The user terminal receives the password and the two-dimensional bar code from the user. [Reference numerals] (AA) Password; (BB) Identifying a user through a public key certificate
