Problems solved by technology

[0006] However, in the above process, it has not been proved that the authentication system terminal requiring a password is valid for the user
[0007] More specifically, in the case of modifying an unauthorized terminal so as to appear to be legally authenticated, the user cannot determine that the terminal is an unauthorized terminal
As a result, users are always at risk of misusing or having their passwords stolen through fake authentication system terminals

[0107] (The structure of the authorization system)

[0108] figure 1 It is a schematic diagram showing the structure of an authentication system using an IC card as the first embodiment of the present invention. figure 1 The illustrated authentication system using an IC card includes an IC card 10, an authentication system terminal 20, a portable inspection device 30, and a communication line 40 connecting the authentication system terminal 20 and the portable inspection device 30. The IC card 10 is used as an information processing card having an information processing function.

[0109] The communication line 40 is a telephone line, the Internet, a radio wave connection (wireless communication), or the like.

[0110] When receiving various services using the IC card, the user inserts the IC card 10 into the authentication system terminal 20, and inputs a password (equivalent to authentication information) through the keypad of the authentication system terminal 20.

[0216] Next, a second embodiment of the present invention will be described with reference to the drawings.

[0217] Picture 9 It is a schematic diagram of the structure of an authentication system using an IC card according to the second embodiment. Picture 9 The illustrated authentication system using an IC card includes an IC card 10a, an authentication system terminal 20a, and a portable inspection device 30a.

[0218]In order to receive various services through the IC card 10a, the user inserts the IC card 10a into the authentication system terminal 20a. After the IC card 10a is returned from the authentication system terminal 20a, the user inserts the IC card 10a into the portable inspection device 30a. In accordance with the information displayed on the portable inspection device 30a, the user inputs a password (or authentication information) through the keypad of the authentication system terminal 20a.

[0219] Using the entered password, the authentication system termi...

Abstract

Even in the case a user mistakenly inputs authentication information to a counterfeit authentication system, the authentication information is certainly prevented from leaking out. [MEANS FOR SOLVING PROBLEMS] A legitimacy confirming system is provided with an information processing card, an authentication system for carrying out a mutual authentication with the information processing card and a confirming device. The information processing card is comprised of a legitimacy authenticating means for authenticating the legitimacy of the authentication system, and a masquerade prevention means for carrying out a masquerade prevention processing for a result authenticated by the legitimacy authenticating means. The confirming device is comprised of a verifying means for verifying a result of an authentication that is output from the information processing card and that is subjected to the masquerade prevention processing, and a verified result output means for outputting the result verified by the verifying means in a user perceivable state. The verifying means is not provided in the confirming device but may be alternatively provided in the verifying device.

Description

Technical field [0001] The present invention relates to a validity checking system, a validity checking method, an information processing card, checking equipment and authentication equipment. For example, the present invention will be applied to the following validity checking system, validity checking method, IC card, checking device, and authentication device: it prevents the leakage of authentication information about the user due to impersonation in the authentication system using the IC card, and realizes Secure computer system. This patent application is based on an earlier Japanese patent application No. 2006-254365 filed on September 20, 2006, and claims the priority of the patent application, and all contents of the patent application are incorporated herein by reference. Background technique [0002] As disclosed in Patent Document 1, in an authentication system for a computer system using an IC (Integrated Circuit) card, identity authentication must be performed to co...
