A display 31b notifying that there has not been displayed is displayed.

The input determination unit C12 includes a capacitance change detection unit C12A, and determines whether or not an input to the authentication input units 21d and 31a has been performed.
The capacitance change detection means C12A detects a change in the capacitance of the touch panel 2 when an input is made to the authentication input units 21d and 31a. Therefore, when the electrode member 13 of the input device 11 comes into contact, the identification information of the input device 11 can be received from the change in capacitance. When the finger or the like touches, the capacitance does not change. Identification information is not received. In the first embodiment, the capacitance change detection unit C12A determines that the input device 11 or a finger has touched the area of the authentication input units 21d and 31a (the capacitance has changed). If so, detection of a change in capacitance is started.

The identification information receiving unit C13 receives the identification information from the input device 11 based on the detection result of the capacitance change detection unit C12A. Specifically, the identification information of the input device 11 is acquired from the detection result of the capacitance change detection means C12A.

  The transmission stop signal transmitting means C15 transmits a signal for stopping transmission of information by the electrode member 13 of the input device 11. As an example of the transmission stop signal, the transmission stop signal transmission means C15 of the first embodiment receives an input to the authentication input units 21d and 31a and is authenticated in the area of the authentication input units 21d and 31a. Let black and white blink at intervals for 2 seconds. That is, the black and white blinking images at 100 ms intervals are transmitted to the input device 11 as transmission stop signals via the image display means C11. Note that the transmission stop signal is not limited to a black and white blinking image, and any image set in advance, such as a black image (light-out image) or a pattern image of a specific color, can be used.

(Operation of Example 1)
In the input system S of the first embodiment having the above configuration, when the processing software AP1 is activated and the input device 11 is brought into contact with the authentication input unit 21d of the initial image 21, the electrode member 13 of the input device 11 is pressed. It becomes a state. Therefore, the capacitance of the authentication input unit 21d with which the electrode member 13 contacts via the relay circuit D1 changes according to the identification information. The change in capacitance is detected by the capacitance change detection means C12a, and authentication processing is performed by the authentication means C14. When authenticated by the authentication means C14, the menu image 22 shown in FIGS. 4D and 4E is displayed according to the usage authority stored in association with the authentication information storage means C14A. When a function is selected on the menu image 22, an image 31 of each function is displayed as shown in FIG. 5A. In the image 31 of each function, identification information is transmitted from the electrode member 13 when the input device 11 is brought into contact with the authentication input unit 31a when executing the function. When authentication is performed and the function is executed, a transmission stop signal is output from the authentication input unit 31 a to the input device 11.

Therefore, when authentication is required, such as login and settlement of commercial transactions via the Internet, and execution of login and transfer in the Internet bank, the ID (identification information) or Even if the password (password information) is not input, authentication can be performed simply by placing the input device 11 on the touch panel 2. Therefore, it is possible to use the input device 11 instead of a so-called one-time password (password information valid only for a short period).
Further, in the first embodiment, the identification information for authentication is transmitted through a single electrode member 13 while changing the capacitance. As an example, the identification information of Example 1 can transmit 10 bits (1024 types) of information in one second. Compared to the techniques described in Patent Documents 1 and 2, the total number of identifiable individuals can be calculated. It can be increased easily. The total number of identifiable individuals can be increased or decreased by increasing or decreasing the number of bits, for example, and the transmission time can also be shortened by making the time taken for 1 bit shorter than 100 ms. In addition, for example, it is possible to transmit 20 bits in one second by increasing the number of electrode members 13 to two, and by transmitting the number of electrode members 13, information on identification information that can be transmitted It is possible to increase the amount. That is, the number of electrode members 13 is not limited to one, and can be increased or decreased according to the application and purpose.

In particular, each input device 11 can share other configurations by changing only the identification information stored in the identification information storage means C1. Therefore, as compared with the case where the position of the contact is changed as in the techniques described in Patent Documents 1 and 2, mass production is easy and a reduction in manufacturing cost can be expected.
In the input device 11 according to the first embodiment, the photosensor 14 can receive a transmission stop signal from the touch panel 2. That is, the input device 11 is configured to be capable of bidirectional communication with the tablet terminal 1. And the input device 11 of Example 1 stops transmission of the information by the electrode member 13, when the photo sensor 14 receives a transmission stop signal. Therefore, compared with the case where the transmission stop signal is not transmitted, the relay circuit D1 suppresses power consumption when switching the electrostatic capacity, reduces battery consumption of the electrode member 13, and saves energy.

Furthermore, in the input device 11 of the first embodiment, when the electrode member 13 is pressed against the touch panel 2, the detection switch SW1 is pressed. Therefore, the user can perceive a feeling of pressing the input device 11 with the operation of the switch SW1. Therefore, it is easier for the user to input the touch panel 2 more reliably than when the user cannot perceive whether or not the input device 11 has touched.
Further, when the detection switch SW1 is activated, transmission of identification information to the touch panel 2 is started. Therefore, compared to the configuration in which the identification signal is always transmitted or the case where the identification information is transmitted simply by approaching the touch panel 2, the identification information is displayed in a state in which the user reliably presses the input device 11 against the touch panel 2. It can be sent. Therefore, useless power consumption and transmission of identification information not intended by the user are reduced.

  In the first embodiment, for example, when the identification information input by the authentication input unit 31a of the image 31 is different from the identification information authenticated by the authentication input unit 21d of the initial image 21, it is determined that the image 31 cannot be authenticated. It is also possible to determine. In this case, when performing a process that requires authority, it is possible to prevent another person from performing the process from the middle, and to improve security.

Further, if the authentication information (password) is input every time each operation is performed on a public terminal or a shared terminal, the input becomes complicated for the user. Therefore, at present, a shared terminal or the like often adopts a configuration in which once authenticated, the user enters a login state and thereafter can operate without inputting authentication information. However, in this case, when the user finishes the operation, the user may forget to log out and leave the terminal, which may cause another person to operate the logged-in terminal. .
On the other hand, in the first embodiment, authentication information can be input with a simple operation compared to password input in which a stamp is pressed with the input device 11. Therefore, even if authentication information is input every time an operation requiring authority is performed, the burden on the user is small. Then, for example, after the user approves the document data shown in FIG. 6A, the user authenticates (logs in) with the initial image 21, and then releases the tablet terminal 1 from the hand without performing an operation corresponding to logout. Even if a person different from the user attempts to approve another document data when he / she sits down, the process cannot be executed because there is no input device 11 for the user. Therefore, it is possible to avoid a security risk caused by forgetting to log out.

  In addition, the authentication input unit 21d of the initial image 21 can be authenticated by many people's input devices 11, and a menu image 26 that can use all functions is displayed. The input unit 31a may be configured such that only the input device 11 of a user who has a certain authorization authority can authenticate. In this case, for example, when authentication by the input device 11 of the supervisor who is the authorizer is required, the subordinate logs in with his input device 11 and displays the image of the approval, and the authentication input unit of the image of the approval In 21d and 31a, it is possible that the boss stamps with the input device 11 of the boss. Therefore, when the boss is busy, even if the boss does not operate until the login or approval image is displayed, the subordinate will assist and the boss will stamp in a short time to make the approval process smooth. Is also possible.

Therefore, by making the electrode member 13 of the input device 11 contact the positions of the input units 41a and 41b, it is possible to authenticate whether or not the user has the authority to approve or reject. When authentication is performed, as shown in FIG. 6B, the stamp image 41c is displayed on the approval / rejection input units 41a and 41b, so that the user can confirm the contents input by the user.

(Modification 3 of Example 1)
FIG. 8 is an explanatory diagram of a third modification of the first embodiment of the present invention.

It is possible to authenticate by touching. In this case, when the input units 51a to 51f and the input device 11 at the station match, authentication passes and the stamp image 51g can be attached. The place where the input device 11 is installed is not limited to a railway station, but can be installed at any place such as a road station, amusement facility, a park checkpoint, a cafeteria, or reception of attractions in a theme park. .
Therefore, in the third modification of the first embodiment, the action of pressing the stamp is similar to a physical stamp and intuitively easy to understand compared to the conventional method such as photographing a QR code (registered trademark). Further, unlike a physical stamp, information on which user visited when and where can be collected through the input device 11. Therefore, marketing, advertisement, etc. are also possible using the collected information.

Then, when the input device 11 is in contact with each of the input units 56a to 56c in order and authentication is performed for three persons, a text image 56d of the confidential document is displayed as shown in FIG. 9D. . Therefore, the present invention can be applied to a configuration in which confidentiality is maintained by authentication of a plurality of persons.
It should be noted that in a state where authentication for the number of persons is not performed, the confidential document data is encrypted, and when authentication is performed for the number of persons, it can be applied to an encryption technique called so-called secret sharing. At this time, it is possible to have a configuration in which all of the persons (M) necessary for decryption input by the input device 11. For example, M out of N (> M) persons input by the input device 11. In such a case, it is possible to adopt a configuration for decoding. Thus, for example, when the board of directors consists of five people, it is possible to create a ciphertext that can be decrypted only by three or more stamps.

Means C6 and encoded value transmission means C7.
The random value receiving means C4B receives the random value r when the photo sensor 14 detects black and white blinking different from the transmission stop signal based on the random value r generated by the touch panel 2 of the tablet terminal 1. As an example, the random value transmission method is the same as in the case of the change in capacitance, when the random value r is “101010”, when the random number r is “1”, white light is emitted, and when “0” is black, the random value is black. It is possible to adopt a method such as turning off the light.

The encoding means C6 encodes (encrypts) the private key information stored in advance in the input device 11. Therefore, the random value r is encoded into the encoded value Enc (r).
The encoded value transmission unit C7 transmits the encoded value Enc (r) encoded by the encoding unit C6 to the tablet terminal 1. The encoded value transmitting unit C7 according to the first exemplary embodiment transmits the encoded value Enc (r) to the tablet terminal 1 by changing the electrostatic capacity via the electrostatic capacity changing unit C3.

In FIG. 10, in the control unit Cb of the tablet terminal 1 according to the second embodiment, the authentication unit C14 includes a random value generation unit C14A ′ as an example of an information generation unit and a decoding unit C14B ′ as an example of a decoding unit. .

In the method of directly transmitting the identification information, for example, when the identification information is copied by a malicious attacker while keeping an eye on the input device 11, there is a problem that the attacker can impersonate. However, it is possible to prevent spoofing by configuring challenge-response authentication that is currently widely used by using a secret key and a public key.

(Modification 1 of Example 2)
In the first modification of the second embodiment, it is also possible to create document data with an electronic signature by partially changing the configuration of the second embodiment. For example, in the tablet terminal 1, for document data before an electronic signature as an example of information to which an electronic signature is to be applied, a hash value H (as an example of unique information for authentication is used instead of the random value r in the second embodiment. x). Then, the hash value H (x) is transmitted to the input device 11, and the input device 11 encodes the hash value H (x) with a secret key. The generated encoded value Enc (H (x)) is transmitted to the tablet terminal 1 as electronic signature data. The tablet terminal 1 can create document data with an electronic signature by attaching the electronic signature data to the document data.
When the document data with the electronic certificate is received, the value Dec (Enc (H (x))) decoded using the public key paired with the private key of the input device 11 is the hash value H. It can be confirmed whether or not the owner of the private key has made an electronic signature based on whether or not it matches (x).

For example, when a pen-type input device is used and an electrode member is arranged at the tip of the pen and a sign is written on the input unit 31a with a pen, information is transmitted and received during the period when the electrode member is in contact with the touch panel. It is also possible to adopt a configuration. Therefore, it appears to the user that he / she has written and signed, and the electronic data can be digitally signed using a secret key as electronic data.

FIG. 16 is an explanatory diagram of the input system according to the fifth embodiment and corresponds to FIG. 1 according to the first embodiment.
FIG. 17 is an explanatory diagram of a bottom surface portion of the input member according to the fifth embodiment.
In the description of the fifth embodiment, components corresponding to those of the first and fourth embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.
The fifth embodiment is different from the first and fourth embodiments in the following points, but is configured in the same manner as the first and fourth embodiments in other points.
In FIG. 16, the input system S according to the fifth embodiment includes a figure-type controller 201 as an example of an input member. In the fifth embodiment, as an example, a figure-type controller 201 is used as a controller for a so-called shooting game in which an enemy aircraft is defeated by an attack bullet from the own aircraft while avoiding an attack bullet from the enemy aircraft. The case will be described.

  The figure-type controller 201 includes a columnar pedestal portion 202, similar to the figure-type controller 101 of the fourth embodiment. In FIG. 17, a pair of electrode members 203 are disposed on the bottom surface of the pedestal portion 202.

In the fifth embodiment, relay circuits D1a and D1b are arranged for the electrode members 203a and 20b, respectively.

A phototransistor 204 as an example of an information receiving member is supported between the electrode members 203.
A figure 205 as an example of a doll part is supported on the upper surface of the pedestal part 202 of the fifth embodiment. Note that, unlike the fourth embodiment, the figure 205 of the fifth embodiment is configured such that the posture cannot be changed. Therefore, the variable resistor R1 is not built in the figure 205 of the fifth embodiment.
Further, a shooting button 206 as an example of an input button is disposed on the peripheral surface of the pedestal portion 202 of the fifth embodiment. The shooting button 206 is configured by a known button that is pushed into the pedestal portion 202 when the user pushes it with a finger and projects outward when the finger is released.

FIG. 18 is a functional block diagram of the input system according to the fifth embodiment, and corresponds to FIG. 3 according to the first embodiment.
In FIG. 18, the control unit Ca of the input device 201 of the fifth embodiment, unlike the first embodiment, has a shooting button input determining means C102 and a shooting information transmitting means C103, and the transmission stopping means of the first embodiment. Does not have C5. Further, the fifth embodiment does not include the electrode-off signal reception detection means C4A of the first embodiment.

The shooting button input determining means C102 determines whether or not the shooting button 206 has been input.
The shooting information transmitting means C103 transmits information on whether or not the shooting button 206 has been input. The shooting information transmitting unit C103 of the fifth embodiment uses the second electrode member 203b through the capacitance changing unit C3, and transmits the shooting information to the tablet terminal 1 by the change in capacitance.

  Note that the capacitance changing unit C3 according to the fifth embodiment transmits identification information through the first electrode member 203a when the electrode member 203 contacts the touch panel 2. After the identification information is transmitted, the capacitance changing means C3 of the fifth embodiment always keeps the first electrode member 203a in a state where the capacitance is large. In addition, the capacitance changing unit C3 of the fifth embodiment transmits the shooting information by controlling the relay circuit D1b of the second electrode member 203b after transmitting the identification information. In the fifth embodiment, for example, when the shooting button 206 is input, the shooting information is transmitted by increasing the capacitance for a period of 200 ms and decreasing the capacitance for a period of 100 ms. If not input, information is transmitted in the form of increasing the capacitance for a period of 100 ms and decreasing the capacitance for a period of 200 ms. Note that the method of transmitting information is not limited to this method.

In FIG. 18, unlike the first embodiment, the control unit Cb of the tablet terminal 1 according to the fifth embodiment does not include the authentication unit C14 or the transmission stop signal transmission unit C15, and the body type determination unit C21 and the orientation determination. Means C22, shooting discrimination means C23, and impact detection means C24 are provided. Further, the image display means C1 of Example 5 includes a shooting image display means C11B and an enemy aircraft image display means C11C.
The machine type discriminating means C21 discriminates the type of the figure 205 of the figure-type controller 201 based on the identification information received by the identification information receiving means C13. In the fifth embodiment, as a type of the figure 205, an airplane or a helicopter used as a self-machine in a so-called shooting game is registered in advance. In the fifth embodiment, identification information is assigned to each type of the figure 205, and unique identification information is not assigned to each individual of the figure-type controller 201. Therefore, for example, when the figure 205 has 32 types, 5-bit identification information is sufficient. In the fifth embodiment, the configuration in which the unique identification information is not assigned to each individual of the figure type controller 201 is illustrated. However, the present invention is not limited to this, and the unique identification information is assigned to each individual and received. It is also possible to adopt a configuration in which the model is specified by comparing the identification information and the identification information database.

The orientation determining means C22 determines the orientation of the figure type controller 201. The direction discriminating means C22 of the fifth embodiment has a position on the touch panel 2 of the first electrode member 203a that always has a large capacitance, and a touch panel 2 of the second electrode member 203b that transmits shooting information with a period of 300 ms. A line segment connecting the positions is determined as the orientation of the figure-type controller 201.
The shooting determining means C23 determines whether or not the shooting button 206 is input based on the shooting information received from the second electrode member 203b.
Based on the coordinates of an enemy aircraft image 62 and an attack bullet image 62a, which will be described later, and the position coordinates of the own aircraft (figure-type controller 201), the bullet discrimination means C24 determines whether or not the own aircraft has hit the game. Is determined.

FIG. 19 is an explanatory diagram of an example of a display image of the fifth embodiment, FIG. 19A is an explanatory diagram of a shooting state, and FIG. 19B is an explanatory diagram of a state in which the direction of the input member is inclined with respect to the state of FIG. FIG. 19C is an explanatory diagram of a state in which two different types of input members are used.
The image display means C11 according to the fifth embodiment displays a game image 61 of a so-called shooting game as shown in FIG.
The shooting image display unit C11B according to the fifth embodiment displays an attack bullet image 61a indicating an attack bullet from the own aircraft when the shooting determination unit C23 determines that the shooting button 206 is input. The attack bullet image 61a is displayed corresponding to the attack bullets fired with reference to the position of the figure-type controller 201, specifically, the intermediate position between the electrode members 203a and 203b. Therefore, when the user operates the figure type controller 201 and moves it on the touch panel 2, the reference position of the attack bullet image 61a also changes.
