Embodiment Construction

[0046] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0047] The present invention provides a service that ensures the security of, for example, the exchange of value information using the anti-tampering and authentication functions of an IC card. More specifically, the present invention reduces the card issuance workload of a service provider by allowing multiple services to share a single memory space inside an IC card. Furthermore, the present invention reduces the number of cards that users carry and manage.

[0048] Wherein, when multiple service providers share a single storage area and some service providers are allowed to access the storage space of other providers, the value information set by each service provider may be accessed by other unauthorized service providers.

[0049] According to the present invention, file systems for a plurality of service providers are allocated in a single...

Abstract

File systems for respective service providers are assigned to a single memory area, and a single information storage medium is shared among the plurality of providers. In the initial state, an IC card issuer manages the whole memory area. If another provider is to divide the memory area to make a new file system, it requested to acquire both a right of dividing the memory area and an authentication of the IC card issuer. After the file division, an access to the file system needs to acquire an authentication of the provider that made the file division. When utilizing any service, the user can easily use the IC card as if the IC card were issued by the corresponding provider itself.

Description

technical field [0001] The present invention relates to a data communication device including a relatively large-capacity memory, and a method for managing the memory of the data communication device, in particular, to a method for storing electronic value information in a storage area and transmitting information including A data communication device for security information of electronic payment information, and a method for managing a memory of the data communication device. [0002] More specifically, the present invention relates to a data communication device for allocating a file system for a service provider in a storage area and managing information related to services provided by the service provider using the file system , and a method for managing a storage area of ​​the data communication device, in particular, to a data communication device for distributing files for each of a plurality of service providers in a single storage area A system allowing said plurali...
