Abstract

A mobile device (10) has a noncontact IC (11). Three storage areas are preliminarily formed in the noncontact IC (11). When the mobile device (10) receives an application from a content server (20), a storage area (1) is assigned as a data area dedicated to this application. After that, the mobile device (10) rejects access from any application other than the foregoing application to the storage area (1).

Claims

1. A mobile device comprising:

storing means internally having a predetermined number of data areas;

acquiring means for acquiring an application;

assigning means for, when the acquiring means acquires an application, assigning the application to one of the data areas in the storing means; and

controlling means for performing a control to permit access from the application to said assigned data area.

2. The mobile device according to claim 1, wherein, on the occasion of making access from the application to the data area, the controlling means acquires a PIN from an application definition file of the application to enable said access.

3. The mobile device according to claim 2, wherein the application definition file is an Application Descriptor File.

4. An access control method comprising the following steps carried out by a mobile device with storing means internally having a predetermined number of data areas:

an acquiring step of acquiring an application;

an assigning step of, when an application is acquired in the acquiring step, assigning the application to one of the data areas in the storing means; and

a controlling step of performing a control to permit access from the application to said assigned data area.
