PROBLEM TO BE SOLVED: To provide an authentication system capable of eliminating an authentication error resulting from erroneous input of an authentication element, leakage of the authentication element to a third party, and a process of rewriting the authentication element when the leakage occurs.SOLUTION: After executing user authentication in a terminal 1, an operator 3 selects a command 14 from a screen and executes a command conversion transmission process 5. When the command 14 is transmitted from the terminal 1 to an authentication allocation device 6, the authentication allocation device 6 searches a correspondence table 7a for a corresponding authentication element 8, buries the authentication element 8 in the command 14, and then executes a conversion process 9. In the command conversion transmission process 5, a conversion process result is transmitted to an authentication verification device 11 as a conversion command 10. The authentication verification device 11 inversely converts the conversion command 10 and acquires the command 14 and the authentication element 8. If the authentication element 8 matches an authentication element 12, the authentication verification device 11 verifies that the command 14 is a right command from a command sender. |
