Description

  The present invention relates to a portable terminal device, an IC card authentication control method, and a program that have an IC card authentication function and can register one or more IC cards that permit the authentication.

Conventionally, in a mobile phone device, in order to achieve the objectives such as “user data protection” and “ensure security of the entire device”, input of a personal identification number has been required in a corresponding scene.
However, the PIN number has characteristics such as “the initial values are all the same” and “often associated with personal data of each person”, and there is a weakness that it is easy to guess and easily disturbed by others. It was.

  Therefore, a function for authenticating an IC card has appeared as an alternative means for inputting a personal identification number (see, for example, Patent Documents 1 to 3). This is because an IC card (a plurality of) to be used for authentication is registered in the mobile phone device in advance, and can be used as an alternative means for inputting a personal identification number. By being able to register multiple, it was possible for the user to use it properly. For example, the use of an employee ID card (with an IC chip) and a boarding ticket (with an IC card) depending on weekdays and holidays.

Although this IC card authentication function compensates for the weak point that a personal identification number is estimated, there are a plurality of means for establishing authentication at the same time, which is not desirable in terms of security. This is because few people carry their employee ID cards on weekdays, and it is not necessary to authorize authentication.

For example, multiple IC cards that are registered in conjunction with time data but that are not used at the same time are allowed to authenticate, permit the first IC card, and disallow the second IC card. Convenience and security are improved by performing control to switch to.

  The third feature is that a function for notifying the user at the timing of the switching is provided to make it easy to use. For example, it is easy to use by providing a function of notifying only by the user by switching the standby screen.

The present invention improves the above-described problems of the prior art and further provides convenience to the user. In other words, it is linked to functions and data in the mobile phone device, so that an authenticable IC card does not exist at the same time, but can be switched and used.
In the following, with regard to function linkage, data linkage, and notification functions, their solving means will be described using specific examples. Note that each of the above functions is realized by control of a program read into the mobile phone device.

[Function interlocking]
The function linkage is to switch an IC card that can be authenticated in conjunction with various functions in the cellular phone device, for example, a schedule management function, an alarm function, a GPS (location providing) function, and the like.

Here, the linkage with the schedule management function will be described as a specific example.
First, the schedule management function is a function for managing a user's schedule by filling in the user's schedule or notifying it with an alarm mainly using a calendar or the like. These functions also include a function for the user himself to set holidays, holidays, and anniversaries.

In the present invention, within this schedule management function,
[1] Authenticated IC cards are switched in conjunction with weekdays, holidays, holidays, and anniversary settings [2] Authenticated IC cards can be switched in conjunction with individual schedules set by the user ing.

As a more specific example,
[1] Employee ID on weekdays, tickets on holidays, and electronic tickets on anniversaries can be authenticated In some cases, it can be set as a one-time key to enhance security.

[Data linkage]
Data linkage refers to switching IC cards that can be authenticated in conjunction with various data in the apparatus, such as time data and battery level data (remaining battery level).

Here, the linkage with time data will be described as a specific example.
This function is a function linked with the time data held in the mobile phone device so that it can be switched to a fixed time without setting an alarm or the like.

As a more specific example,
[1] From 8:30 to 17:30, employee ID cards are used. Of course, it can also be used in combination with the functions in this apparatus. For example, it can be used in combination with the previous schedule management function, such as “this time on weekdays” and “this time on holidays”.

[User notification function]
The user notification function enables notification of “now an IC card that can be authenticated” by a method that is known only to the user when an IC card that can be authenticated is switched or temporarily disabled. Yes.

As a specific example,
[1] At the timing of switching, the standby screen, icons, etc. are changed to those associated in advance by the user. Of course, higher security is required and it is possible not to use this function.

  Thus, even if there are a plurality of authenticable IC cards, the presently known IC card is notified by a method that can be understood only by the user, thus providing ease of use.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration of main apparatuses in the present invention.

  In the present invention, first, it is necessary that the contactless IC card 14 that permits authentication instead of the password is registered in the IC card storage unit 7 (part of the storage unit 6). Under the circumstances, the present invention is effective in a case where the contactless IC card 14 is authenticated through the reader / writer 13 instead of the password input.

"When interlocking with functions in the device"
For example, a schedule function, an alarm function, etc. operate | move according to the value stored in the control part 8 with reference to the memory | storage part 6. FIG. At the same time, the contents are notified to the user together with the sound processing unit 3, the image processing unit 4, and the display unit 10.

  At this time, the control unit 8 refers to the IC card storage unit 7, and if the operation performed immediately before and switching of the IC card are associated with each other, the IC card that can be authenticated is switched or invalidated accordingly. Or

  Further, at this time, if the user notification function is ON, the control unit 8 controls the audio processing unit 3, the image processing unit 4, the display unit 10, and the like accordingly to notify the user.

"Other cases"
For example, if the association of IC card switching is outgoing / incoming, power ON / OFF, or position information by GPS, the switching is performed in conjunction with the wireless processing unit 2, the power unit 12, and the GPS 9, respectively.

  Among the above, the control unit 8 performs switching of the IC card and determination of notification to the user, but the criterion of the determination is that of FIG. 3 stored in the IC card storage unit 7 The file has the structure shown in FIGS.

  The file in FIG. 3 is a summary of a list registered as IC cards that can be authenticated in the apparatus and a notification method at that time. This file is updated every time an IC card is registered.

  The file in FIG. 4 associates functions and data in the apparatus with an IC card that is to be enabled (to be authenticated) at that time. Further, whether or not to notify the user at the timing of switching is also associated. This file is updated mainly by user's own operation.

  The file in FIG. 5 shows an IC card that can be currently authenticated. This file is updated every time an authenticable IC card is switched based on the association shown in FIG.

The operation of the embodiment of the present invention will be described.
The flow from the activation of a certain function in the device to the switching of an IC card that can be authenticated in conjunction with the function and notification to the user will be described with reference to the flowchart of FIG. 2 and FIGS. To go.

First, each process and conditional branch in the flowchart of FIG. 2 will be described.
When an arbitrary function in the apparatus is activated (step S1), it is determined whether or not the function is associated with IC card switching (step S2). If the IC card switching registration has not been performed (step S2 / NO), the process ends. When the IC card switching registration is performed (step S2 / YES), the IC card is switched according to the association (step S3). An authenticable IC card is updated (step S4). At the time of switching the IC card, it is determined whether or not to notify the user (step S5). The user is notified according to the association (step S6).

  The above is the overall flow, and when performing conditional branch determination (steps S2 and S5) and processing associated therewith, the determination is made with reference to FIGS.

Next, the process of referring to FIGS. 3 to 5 from the overall flow will be described with specific examples.
As preconditions, FIG. 3 shows a list of IC cards currently registered in the apparatus, FIG. 4 shows the relationship between IC cards defined by the user and functions in the apparatus, and FIG. 2 and the function activated in step S1 in the flowchart of FIG. 2 is assumed to be a schedule function at the time of ◯ / □, xx set in FIG.

  First, in the process of step S1, the schedule function in the apparatus is activated at the time of ◯ / □, XX.

  Then, the apparatus refers to the file (association list file) shown in FIG. 4 and determines whether the previously activated function is associated to switch an authenticable IC card (step S2). In this case, according to FIG. 4, it can be determined that the schedule function at the time of ◯ / □, xx is related to switch the authenticable IC card to No2. By the way, No2 can be read as a ticket from FIG.

  After switching the IC card in step S3, the content in FIG. 5 is updated to the content in FIG. 6 in step S4.

  Thereafter, the apparatus similarly refers to the file shown in FIG. 4 and determines whether to notify the user (step S5). In this case, according to FIG. 4, since the notification function is ON, notification is performed according to the notification method of FIG. Specifically, in this case, the battery icon is switched to ΔΔ (step S6).

As described above, the present invention has the following effects.
The first effect is that the security is improved by switching to one or temporarily disabling a plurality of authenticable IC cards at the same time.
The second effect is that the timing of the switching is linked to the function and data in the apparatus, so that it is in line with the user's schedule and location, and the convenience is enhanced.
The third effect is that the “IC card that can be authenticated” is notified by a method that can be understood only by the user at the timing of the switching, and thus provides ease of use.

  In the description of the above embodiment, “function interlocking” and “data interlocking” have been described to operate separately. However, the function and data are combined to control the switchable IC card. Also good.
