Description

  The present invention relates to a portable terminal having a non-contact IC card function.

The non-contact IC card can exchange information without bringing the card and the reading device into contact with each other by wireless communication means. Therefore, the non-contact IC card has no obstacle caused by electrical contact and has a higher durability of the reading device than the conventional contact type IC card. There is an advantage. In addition, since the amount of information that can be handled is large compared to conventional magnetic cards and various information can be stored, it has recently been put into practical use as electronic money, commuter passes, tickets, etc., and this non-contact IC card is used in portable terminals such as mobile phones. Implementation of itself or its function is also performed.
Conventionally, when a non-contact IC card is used as electronic money, a commuter pass, a ticket, etc., the user is not confirmed at the time of use. Therefore, when a non-owner acquires a contactless IC card due to loss or theft, the acquirer uses the card function illegally, for example, consumes the remaining amount of electronic money stored in the contactless IC card. There was a problem that it was possible to do.
In order to prevent such unauthorized use, when a mobile terminal handling electronic money is lost, the mobile terminal is contacted from outside the lost mobile terminal and the electronic money function of the mobile terminal is stopped. And a technique for collecting the remaining amount of electronic money in an electronic money management server is disclosed (for example, see Patent Document 1).

In addition, when using the function of a non-contact IC card built in a portable terminal, a means for storing a personal identification number / password known only to the original user is provided in the portable terminal, so that a person who tries to use it can use it. A technique is also disclosed in which a non-contact IC card can be used only when the personal identification number / password is input and the personal identification number / password matches a previously stored personal identification number / password (see, for example, Patent Document 2).

  However, the problem of the method disclosed in Patent Document 1 is that when a mobile terminal is in an environment where radio waves do not reach, the electronic money function cannot be stopped and the value of the electronic money cannot be collected, and unauthorized use cannot be prevented. In the point. Because there may be many environments where radio waves do not reach the mobile terminal, such as underground or in buildings, unauthorized users should turn off the mobile terminal and avoid radio waves reaching where radio waves can reach. It was still possible to activate the mobile terminal only when in the place and illegally consume the value of electronic money at that place.

  Moreover, although the method disclosed in Patent Document 2 solves the above-described problems, there is a problem that the time and effort required when a legitimate owner uses electronic money also increases. As an advantage when using a non-contact IC card as electronic money, since the time required for payment may be shortened, it is not desirable to increase the effort and time required for payment in this way.

  Therefore, in view of the above problems, the present invention provides a portable terminal that prevents unauthorized use by performing user authentication with a simple method without increasing time and effort even in an environment where radio waves do not reach. The purpose is to do.

<First Embodiment>
(Configuration of mobile terminal)
As shown in FIG. 1, the mobile terminal 100 according to the first embodiment includes a control unit 101, an authentication processing unit 102, a non-contact IC card function unit 103, and an input unit 107.

  The control unit 101 controls the operation of the mobile terminal 100 as a whole, and includes a CPU, a program that operates on the CPU, and a memory that stores the program.

  After receiving the authentication information 110 from the input unit 107, the authentication processing unit 102 authenticates whether the user is a valid user, and transmits the authentication result to the non-contact IC card function unit 103 as an authentication determination signal 111. In the first embodiment, the authentication determination signal 111 is 1 if the authentication result is correct and 0 if it is not correct.

  The non-contact IC card function unit 103 includes a CPU 104, a memory 105, and a transmission / reception unit 106. The contactless IC card function unit 103 communicates with the outside of the portable terminal through the internal transmission / reception unit 106 when it is determined by the determination unit 311 described later that it matches, that is, when the authentication determination signal 111 is received. And the value of the internal memory 105 are calculated by the CPU 104 to provide a function as a non-contact IC card.

There are various specific methods of using the non-contact IC card function. In the first embodiment, the use as electronic money is assumed. At this time, for example, when the amount of money B is consumed via the transmission / reception unit 106 from the remaining amount A stored in the memory IC, the non-contact IC card function unit 103 sends A, B, etc. to the control unit 101 as a settlement signal 112. You may be notified.
The input unit 107 receives an operation instruction from a user of the portable terminal 100 and uses, for example, a keyboard or a pointing device. However, the input unit 107 and the authentication processing unit 102 are not necessarily configured to be physically independent. For example, as illustrated in FIG. 2, the input unit and the authentication processing unit can be shared.

  The input unit / authentication processing unit 300 includes nine buttons from the button 301 to the button 309 and a conversion unit 310 that converts simultaneously pressed signals of the nine input buttons into serial signals (signals transmitted to the CPU). And a determination unit 311 for comparing the serial signal and the simultaneously pressed pattern of the input buttons (user specifying information 113). This pre-stored input button simultaneous pressing pattern can be arbitrarily changed by the user.

  Here, a case where a simultaneous pressing pattern of a plurality of buttons 301 to 309 included in the mobile terminal 100 is used as a user authentication method will be described.

  In the first embodiment, the button used for detecting the simultaneous pressing pattern may be a button dedicated to detecting the simultaneous pressing pattern, or may be used in combination with an existing button for realizing a mobile phone function or a camera function. Although not limited to the number or shape, the first embodiment shows an example in which the number of existing buttons is nine and four of them are used together for authentication by a simultaneous pressing pattern.

  When the number of simultaneously pressed buttons is N, in order to check whether or not all the buttons are pressed, a signal line is required from each button, but many signal lines are prepared inside the portable terminal. In general, as shown in the example of FIG. 2, the buttons are arranged at the intersections of the wirings prepared on the grid, and the conversion unit 310 serially positions the position information of the vertical and horizontal signal lines of the pressed buttons. Generally, it is converted into a signal and transmitted. For example, in the example of FIG. 2, when only the button 301 is pressed, the signal lines 321 to 326 are 1, 0, 0, 1, 0, 0, respectively, and the button 301 and the button 306 are pressed simultaneously. In this case, it becomes 1, 1, 0, 1, 0, 1. The conversion unit 310 transmits the information thus converted to the control unit 101 as the input signal 114.

  Normally, the control unit that has received the converted signal determines which button has been pressed based on this input signal. However, when only one button is pressed at the same time, the button pressed from the input signal can be uniquely determined, but when a plurality of buttons are pressed at the same time, it may not be determined from the input signal. For example, the buttons that give input signals 1, 1, 0, 1, 0, 1 are pressed when the number of pressed buttons is three (button 301, button 303, button 304), and (button 301, button 301). 303, button 306), (button 301, button 304, button 306), (button 303, button 304, button 306), and four cases, one of (button 301, button 303, button 304, button 306) There are streets that cannot be judged from the input signal alone.

  In the first embodiment, regarding the buttons used for simultaneous pressing, that is, the button 302, the button 303, the button 305, and the button 306, separate signal lines 327, 328, 329, and 330 are prepared for the determination unit 311. It is assumed that the simultaneous pressing is detected by this signal line. However, the arrangement of the physical buttons or on the grid so that the conversion unit 310 can determine the simultaneous pressing pattern only by the value converted in series and transmitted. Allocation may be considered.

(Operation of mobile terminal)
Next, the operation of the mobile terminal according to the first embodiment will be described with reference to FIG. When the user intends to use the function of the non-contact IC card, the user inputs a predetermined button simultaneous pressing pattern, for example, simultaneously presses the button 302, the button 303, the button 305, and the button 306.

  First, in step S101, the control unit 101 initializes the authentication determination signal 111 to off.

  Next, in step S <b> 102, the control unit 101 periodically checks whether new authentication information 110 is input from the input unit 107 and waits until the authentication information 110 is input. Meanwhile, in step S108, the value of the authentication determination signal is turned off.

  Next, in step S103, when the authentication information 110 is input, the control unit 101 gives the authentication processing unit 102, and the user identification information 113 stored in the control unit 101 in advance is also sent to the authentication processing unit 102 at the same time. give. At this time, the pressed states of the four buttons are input to the determination unit 311 as signal lines 327, 328, 329, and 330, respectively, and are arranged in that order, and are handled as the authentication information 110 inside the determination unit 311. In addition, as the user identification information 113, how to press the buttons 302, 303, 305, and 306 is determined in advance, and is stored in the memory of the control unit 101 as the user identification information 113.

  In addition, although various information can be used for the authentication information 110 and the user identification information 113, for example, when authenticating using visual information such as an iris or a fingerprint, it is expressed as image information, that is, a bit pattern. Can do. Further, the confirmation of the coincidence between the authentication information 110 and the user specifying information 113 may be performed by extracting feature amounts from the images and comparing them.

In step S104, the authentication processing unit 102 determines whether or not the authentication is correct based on whether or not they match.
If the authentication result is correct, the authentication processing unit 102 turns on the authentication determination signal 111 in step S105. If not, the authentication processing unit 102 turns off the authentication determination signal 111 in step S106.

  In step S107, the non-contact IC card function unit 103 provides the function of the non-contact IC card function while the authentication determination signal 111 is on, and communicates with the outside through the transmission / reception unit. During this time, necessary information is transmitted to the control unit 101 as a settlement signal 112 as appropriate.

  On the other hand, when the authentication determination signal 111 is off, the non-contact IC card function unit 103 does not provide the function and waits until the authentication determination signal 111 is turned on. The control unit 101 repeatedly performs the authentication process while the authentication information 110 is provided from the outside. When the authentication information 110 is not provided, the control unit 101 turns off the authentication determination signal 111 to stop the non-contact IC card function. (S108).

  In the first embodiment, the simultaneous pressing pattern of a plurality of buttons is used as the authentication information. However, the authentication information may include time intervals when one or more buttons are pressed. Further, the present invention is not limited to button press information, and can be realized by using other information that the user can give to the terminal, such as built-in acceleration sensor, camera lid, and opening / closing information of the main body liquid crystal unit.

(Action and effect)
According to the mobile terminal 100 according to the first embodiment, user authentication is performed by simultaneously pressing the input buttons 301 to 309. In this way, since a user can be instantly authenticated by a simple method at the time of use, wireless radio waves can be generated without increasing the time and effort when a legitimate user uses a non-contact IC card. Unauthorized use can be prevented even in places that do not reach.

  In addition, in the mobile terminal 100 according to the first embodiment, the simultaneous pressing pattern of the input buttons stored in advance can be arbitrarily changed. For this reason, it is possible to periodically change the simultaneous pressing pattern and perform safer user authentication.
