BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal equipped with an IC chip that is powered and driven by wireless communication with an external device, and an IC card used in association with the portable terminal, and more particularly to an external device. The present invention relates to a portable terminal that is powered by wireless communication with a device and is driven and that has an IC chip having a memory function, a control method thereof, and an IC card having a memory function.

More specifically, the present invention relates to a portable terminal in which one or more applications are assigned to a memory area on an IC chip, a control method therefor, and a memory area having one application.
The present invention relates to an IC card allocated by the above applications, and in particular, a mobile terminal for controlling access right for each application allocated to a memory area on an IC chip and its control method, and each application allocated to a memory area. The present invention relates to an IC card for controlling access right to

2. Description of the Related Art Conventionally, various devices using personal identification numbers and passwords have been devised and put to practical use for personal identification and authentication processing. (Here, in general, "PIN" refers to a character string represented by a combination of numbers from 0 to 9, and "Password" uses general characters such as alphabets in addition to numbers. (In this specification, the personal identification number and the password are collectively referred to as a "personal identification code".)

For example, when using a cash card in a bank or other financial institution, the cash
Prompt the user to enter a personal identification number or password using a dispenser, etc. as a means of personal authentication, and after confirming that the user has entered the correct personal identification number or password, withdraw from the cash dispenser, etc. It is designed to operate.

[0005] In addition to this, application of a secret code, such as input of a retreat code of a safety box installed in an accommodation facility such as a hotel, input of a password when logging in to a computer, or for concealing information on an information terminal Examples vary.

Conventionally, in a storage medium such as a magnetic stripe arranged on one bank cash card, only a storage area usable only for the bank is provided. Therefore, the input of the personal identification number or password as described above is only an access to this single storage area. Therefore, the user needs to prepare a card for each purpose or use and properly use a plurality of cards.

Recently, non-contact type IC cards have become widespread. For example, ICs installed at cash dispensers, concert hall entrances, station ticket gates, etc.
The card reader / writer can contactlessly access the IC card held by the user. Here, the user inputs the personal identification number and password to the IC card reader side, and collates the input personal identification number and password with the personal identification number and password stored on the IC card. Identity verification or authentication processing is performed between the card reader / writer. When the identity verification or the authentication process is successful, for example, the application stored in the IC card can be used.
Here, as the application held by the IC card, for example, value information such as electronic money or electronic ticket can be cited.

[0008] Recently, IC cards having a relatively large capacity storage space have appeared and have become popular along with the improvement in miniaturization technology. Since a conventional cash card or the like carries only a single storage area, that is, a single application, it is necessary to carry a plurality of cards for each use or purpose. On the contrary,
According to such an IC card with a large-capacity memory, a plurality of applications can be stored at the same time, so that one IC card can be used for a plurality of purposes. For example, two or more applications such as electronic money for making electronic payments and electronic tickets for entering a specific concert venue are stored on one IC card, and one IC card can be used for various purposes. It can be applied to various uses.

Further, by mounting such an IC card having a large-capacity memory function (or an IC chip having an IC card function as a semiconductor chip) on a mobile terminal such as a mobile phone, a user can carry it. By possessing the terminal, electronic value information such as electronic payment can be exchanged with the outside.

Since conventional cash cards have only a single purpose (discussed above), a magnetic stripe on a cash card can manage the security of the entire card by having a single PIN or password. It was

On the other hand, in an IC card with a memory function capable of holding a plurality of applications and a mobile terminal equipped with such an IC card (or IC chip), it is necessary to control the access right for each application. There is. This is because, if access to all the applications on the IC card is opened with only one secret code, the security at the time of loss or theft is significantly lowered.

Although the degree of coupling between the antenna L _RW on the reader / writer 101 side and the loop coil L _c on the IC chip 50 side varies depending on the positional relationship with each other, it is assumed that one transformer is formed as a system. It can be captured and modeled as shown in FIG.

The reader / writer 101 modulates the current I _RW flowing through the antenna L _RW , so that the voltage VO induced in the loop coil L _c on the IC card is modulated, and the reader / writer 101 is used to do so. / Writer 101 can perform data transmission to the IC chip 50.

The personal identification code thus input is transferred to the collating section 53 in the IC chip 50 via the wired interface 52 (step S2).

Next, the collation unit 53 compares and collates the personal identification code set for each application assigned to the memory 52 with the personal identification code input via the user input device 12 (step S3). .

Then, as a result of the comparison and collation, the user is given the access right regarding the application having the matching secret code (step S4). The storage area assigned to the application to which the access right is given can be accessed from the reader / writer 101 side by wireless communication.

Of course, the collation unit 53 not only collates the personal identification code received via the wired interface 54 (that is, entered by the user on the portable terminal 10), but is also received via the RF unit 51 (that is, It is also possible to collate the personal identification code (which is input by the user on the external device 100).

Also, the reader / writer 1 after the access is permitted
When a series of transactions with 01 is completed, the control unit 55 interprets this and the wired interface 54

Alternatively, the control unit 55 controls the wired interface 5 after normal or abnormal end of the transaction.
4 or the power of the mobile terminal 10 is turned off (that is, the reader / writer 50).
Radio wave from the side is cut off and lost)).
