[Prior art]

 2. Description of the Related Art Conventionally, various authentications for ensuring security have been performed between a higher-level information processing device (hereinafter, referred to as a server) and a communication terminal device. In particular, in fields such as finance and medical care, stricter authentication is required, and various authentication systems have been proposed to meet the demand. For example, the security method described in Japanese Patent Application Laid-Open No. 1-205290 discloses a data collation device that performs personal authentication by collating data from a key input device with data from a card reading device, and further includes an electronic key device. In addition to the data from the key input means and the data from the card reading means, the matching is performed in consideration of the data from the electronic key device.

[0003] As described above, when security is to be stricter, the easiest method is to add new keys one after another and prevent access to the server unless all keys are released. It is. However, if such keys are increased, it is necessary to perform operations many times before accessing the server, which is difficult for the user to use. In particular, in a recent communication terminal device in which operability is emphasized, such a method of simply increasing the number of keys is not always preferable.

[0004] On the other hand, recently, communication terminal devices that improve operability while considering security have been provided. This communication terminal device has two types of IC cards, and a system in which one card is used as an ID card for authentication and the other card is used as a service card for accessing a specific home page. It has become. As a result, a user can automatically access a specific homepage simply by inserting an ID card to perform authentication with a server and then inserting a service card.

[0005]

[Problems to be solved by the invention]

 However, such a communication terminal device having two types of IC cards has a problem that security is not sufficient because only authentication with a server using an ID card is performed. In particular, when this communication terminal device is used as a communication terminal device for electronic money or electronic transactions, it can be said that security is insufficient.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a communication terminal device in which security is enhanced by performing authentication between two types of IC cards. To provide an authentication system.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram schematically illustrating an authentication system for a communication terminal device according to the present invention. That is, the server 1 and the communication terminal device (internet terminal) 2 according to the present invention are connected through the communication line 3, and when two types of IC cards 4 and 5 are inserted into the communication terminal device 2, the server 1 In addition to the authentication performed between the IC card 4 and the server 1 for authentication, the authentication is also performed between the IC cards 4 and 5.

FIG. 2 is a block diagram showing an electrical configuration of the authentication part of the communication terminal device 2, and corresponds to claims 1 and 2. Since this communication terminal device 2 has two types of IC cards 4 and 5, two IC card reading units 21 and 22 for reading data written in these IC cards 4 and 5 are provided. Have.

On the other hand, in the memory of the IC card 4 for authentication with the server 1, data for server-to-server verification and data for card-to-card verification are stored. In the memory No. 5, data for inter-card collation is stored. The data for server-to-server verification and the data for card-to-card verification are naturally different data in consideration of security.

The inter-card collation data read from the IC cards 4 and 5 by the IC card readers 21 and 22 is guided to the inter-card collation unit 23, and the output of the inter-card collation unit 23 is output. , And a main control unit 24 including a collation data output unit. In addition, data for server-to-server verification read from the IC card 4 by the IC card reading unit 21 is guided to the main control unit 24. In the communication terminal device 2 having such a configuration, the authentication operation with the server 1 is performed as follows. Hereinafter, the authentication operation will be described with reference to the flowchart shown in FIG.

When the user inserts the two types of IC cards 4 and 5 into the IC card reading units 21 and 22, respectively (when it is determined Yes in step S1), the IC card reading units 21 and 22 are inserted. The inter-card collation data is read from the IC cards 4 and 5, and is input to the inter-card collation unit 23 (step S2). Further, the IC card reading section 21 reads data for server-to-server comparison from the IC card 4 and inputs the data to the main control section 24. The main controller 24 temporarily stores the input data for server-to-server comparison in a buffer (not shown) (step S3).

On the other hand, the inter-card collation unit 23 compares the input data with each other to determine whether or not both data match (step S 4). That is, the first authentication is performed. If the two data do not match, an error signal is sent from the inter-card matching unit 23 to the main control unit 24 (step S5). Based on this error signal, the main control unit 24 cancels the server-to-server collation data stored in the buffer, displays an error on a display unit (not shown), and ends the connection process thereafter (step S6).

On the other hand, when the two data match (Yes in step S4), a match confirmation signal is sent from the inter-card matching unit 23 to the main control unit 24 (step S7). The main control unit 24 transmits the server-to-server collation data stored in the buffer to the server 1 via the communication line 3 based on the coincidence confirmation signal (step S8). Thereafter, verification (second authentication) is performed by the server 1 using the transmitted server-to-server verification data, and when the card is authenticated, the communication line between the server 1 and the communication terminal device 2 is established. Is established, and the subsequent processing is performed.

That is, according to the authentication system of the communication terminal device of the present invention, the connection with the server 1 cannot be established without the two types of IC cards 4 and 5. Therefore, for example, even if one IC card 4 is lost, if the other IC card 5 is at hand, there is no fear that the lost IC card 4 is misused. In the case of a conventional communication terminal device, authentication is not performed between the IC cards 4 and 5, so that authentication can be performed with the server 1 if only the IC card 4 is provided, and the other IC card 5 is provided. Although the lost IC card 4 may be misused, such a problem does not occur in the communication terminal device of the present invention. In other words, the system is more secure. In addition, since the user only needs to insert two types of IC cards and does not need to enter a password or a password, the operability is far superior to the conventional one.

FIG. 4 is a block diagram showing another embodiment of the authentication part of the communication terminal device 2 according to the present invention, and corresponds to claim 3. That is, the configuration is the same as that shown in FIG. 2 except that a password collating unit 25 is added. The output of the IC card reading unit 22 is guided to the password collating unit 25, and the output of the password collating unit 25 is The configuration is guided to the inter-card matching unit 23 and the main control unit 24. It should be noted that a password input by a user from a keyboard or the like (not shown) is guided to the password collating unit 25. In addition, in the memory of the IC card 5, in addition to an area for storing inter-card collation data, an area for writing a password is secured. In this area, a password input by the user in advance is written. It is to be absorbed. That is, the authentication system of the communication terminal device 2 has a configuration in which security is further enhanced.

In the communication terminal device 2 having such a configuration, an authentication operation is performed with the server 1 as follows. Hereinafter, the authentication operation will be described with reference to the flowchart shown in FIG. When the user inserts the two types of IC cards 4 and 5 into the IC card reading units 21 and 22, respectively (when Yes is determined in step S11), the IC card reading units 21 and 22 The data for inter-card collation is read from 4, 5 and inputted to the inter-card collation unit 23 (step S12). Further, the IC card reading section 22 reads the personal identification number from the IC card 5 and inputs this to the personal identification number collating section 25 (step S13).

The IC card reading section 21 reads data for server-to-server verification from the IC card 4 and inputs the data to the main control section 24. The main control unit 24 temporarily stores the input inter-server collation data in a buffer (not shown) (step S14). Thereafter, when the user inputs a personal identification number from a keyboard (not shown) or the like, the personal identification number is input to the personal identification number collating unit 25, and is collated with the personal identification number read from the IC card 5 (step S15). If the passwords do not match, an error signal is sent from the password collating unit 25 to the main control unit 24 (step S18). Based on this error signal, the main control unit 24 cancels the server-to-server collation data stored in the buffer, displays an error on a display unit (not shown), and ends the subsequent connection processing (step S19).

On the other hand, when both passwords match (in the case of Yes in step S15), a match confirmation signal is sent from the password matching unit 25 to the inter-card matching unit 23 (step S16). The inter-card collating unit 23 compares the inter-card collating data input from the two IC card reading units 21 and 22 based on the coincidence confirmation signal, and determines whether or not both data coincide (step S1). S17). If the two data do not match, an error signal is sent from the inter-card matching unit 23 to the main control unit 24 (step S18). The main control unit 24 cancels the server-to-server collation data stored in the buffer based on the error signal, displays an error on a display unit (not shown), and ends the subsequent connection processing (step S19).

On the other hand, if the two data match (Yes in step S17), a match confirmation signal is sent from the inter-card matching unit 23 to the main control unit 24 (step S20). The main control unit 24 transmits the server-to-server collation data stored in the buffer to the server 1 via the communication line 3 based on the coincidence confirmation signal (step S21). Thereafter, verification (second authentication) is performed by the server 1 using the transmitted server-to-server verification data, and when the card is authenticated, the communication line between the server 1 and the communication terminal device 2 is established. Is established, and the subsequent processing is performed.

That is, according to the authentication system for a communication terminal device of the present invention, even if there are two types of IC cards 4 and 5, connection with the server 1 cannot be performed unless the user inputs a correct password. It has a configuration. Therefore, for example, even if both the IC cards 4 and 5 are stolen, the situation that the two types of the IC cards 4 and 5 are abused immediately is avoided, and the necessary procedure during that time is avoided. Can be taken. In this embodiment, in addition to inserting two types of IC cards, the user needs to input a personal identification number. However, the operability is not inferior to the conventional one, and rather, security is improved. Considering the degree of reinforcement, it is much better than the conventional one.

In the above-described embodiment, an area for writing a password is secured in only one IC card 5 and a password input by a user in advance is written, but the other IC card 4 is also written in the other IC card 4. Similarly, an area for writing a password may be secured, and a password input by the user in advance may be written. In this case, the collation of the personal identification number in step S15 is also performed on the IC card 4, and the operation proceeds to step S16 only when the personal identification numbers of both the IC cards 4 and 5 match, and the inter-card collating unit 23 Then, a match confirmation signal may be transmitted.

In each of the above-described embodiments, the two types of IC cards 4 and 5 are used only for authentication. For example, the IC card 4 is used as an ID card for authentication, and the other IC card 5 is used for authentication. It is possible to use a service card that serves both as a service and for accessing a homepage. A service card is a card that has a specific homepage address (URL address) and is set to automatically access that specific homepage address simply by inserting it into the communication terminal device. is there.

In this case, for example, as indicated by a broken line in FIG. 2, the output of the IC card reading unit 22 is connected to the main control unit 24 and the data for accessing the home page read from the IC card 5 (the home page address). ) May be output to the communication line 3 through the main control unit 24.
