BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a system for acquiring a data field in an integrated circuit card (IC
card) for multiple services. The system according to the present invention discriminates whether or not a service for which a data field area is acquired is provided by an authorized source, and controls the acquisition of the data field area within an allowable range.
2. Description of the Related Art In an IC card for multiple services, all the services to be provided are not always determined upon card issuance. The IC card often has vacant areas.
When the IC card has vacant areas, some services may be additionally provided to the vacant areas in the card after card issuance.
The source which additionally provides a service must not be an arbitrary third party, but one of several limited companies, organizations, company groups, organization groups, or the like. ~lso, the data field area used must be limited. If a given service supplier is allowed to use any size of area, another would find it difficult to additionally provide a service. Therefore, it is desired that each service supplier be allowed to use only up to a predetermined size of area.
In a conventional system for acquiring a data field area, the data field area is additionally acquired based on the area size demand input from a terminal apparatus to an IC card and the data field information already formed in the IC card.
In the conventional system, data field formation demand input from a terminal apparatus can be accepted regardless of the demander, and the data field area, corresponding to the demanded area size is acquired in so far as there is a vacant data field area in the IC
card. In the conventional system~ therefore, there are problems that, if only a former of a data field obtains a right and approval for forming an area, a data field may be formed in the IC card by an unauthorized source, or the data field area in the IC card may be exclusively occupied by a specific service supplier, and there may be a disadvantage that, if an attempt is made to add an additional service to the IC card, there is no area vacant for such an additional service.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved system for data field area acquisition wherein a plurality of area user identifications and authentication codes and usable area size data are stored in an IC card upon issuance of the IC card. A
data field formation demand by a person other than an authenticated area user or a data field formation demand for an area larger than a predetermined size is rPjected, so the IC card can be protected from illegal data field formation.
According to the present invention, there is provided a system for data field area acquisition in an IC card for multiple services, the system including: a plurality of data fields for storing data; an ar~a user identification input unit; an area user authentication code input unit; an area size demand input unit; an area user authentication unit; an area size calculating unit for calculating a remainder area for an authenticated area user; a table storage unit for storing table for data field control; and a data field area acquiring unit. The calculation of a remainder area for user authenticated by said area user authentication unit is carried out based on an input area size demand and information stored in the tble storage unit. Based on the cumulati~e result of the area user authentication and the calculation of the remainder area for the authenticated area user, acquisition of an additional data field area is carried out within a limit of usable area size.

DESCRIPTION OF THE PREFERRED EMBODIMEN~
Prior to a description o~ a preferred em~odiment of the present invention, an IC card as used both in the system of the present invention and a conventional system will be described. Figures 1 and 2 are for explaining an IC card. As shown in Fig. 1, an IC card has contacts, an integrated circuit module arranged beneath the contacts, and an area to be em~ossed.
Figure 2 shows a terminal apparatus electrically connected to the IC card, a program portion for requesting formation of a data field, and a transmission path through which an area user identification and an authentication code (AC code) designated by the program r - -and an-area--size~demand are transmitted to the IC card.
The IC card includes a CPU as a data processor, a memory, such as EPROM and/OR EEPROM, for storing input information, control information, and data fields, and a ROM for storing control programs. In addition, a plurality of metal ~ontacts for electrically contacting an external apparatus are provided on the surface or back of the car~.
Figure 3 shows an example of a conventional system for acquiring a data field area~ In Fig. 3, reference numeral 13' denotes a portion for inputting an area size demand; 81, 82, and 83, data fields already formed in an IC card; 80, an additionally acquired data field; and 4', a portion for acquiring data field data.
In the conventional system shown in Fig. 3, a data field formation demand sent from a terminal apparatus is accepted regardless of the requester when the requester is authenticated by general authentication such as a personal identification number and an authentication code for an IC card. Thus, a data field area corre-sponding to an area size demand is acquired by the portion 4' as long as the IC card has a vacant area. ~n this manner, a data field is additionally formed.
A system for data field area acquisition in an IC
card for plural services according to an embodiment of the present invention will now be described with reference to Figs. 4 and S. Figure 4 shows a system according to an embodiment of the present invention.
The system of Fig. 4 includes an area user identification inputting portion 11, an authentication code inputting portion 12, a portion 13 for inputting an area size demand, area user identifications 51, area user authentication codes 52, usable area sizes 53, and a storage 5 for a table for data field control, con-stituted by the plurality of area user identifications51, the authentication codes 52, and the usable area sizes 53.
~ _ s ~~ - - -The system of Fig. 4 also includes memories for area user identifications 61, 62, and 63 corresponding to the data fields, area size information 71, 72, and 73 corresponding to the data fields, data fields 81, 82, and 83, an area user identification 60 corresponding to 9~
a data field 80 to be additionally acquired, an area size information 7~ of the data field to be additionally acquired, and an additionally acquired data field 80.
- The system of Fig. 4 further includes an area user authentication portion ~, a portion 3 for calculating a remainder area for an authenticated area user; and a portion 4 for additionally acquiring a data field area.
The operation of the system shown in Fig. 4 will now be described. The authenticating portion 2 compares an input area user identification from the portion 11 and an input authentication code from the portion 12 with a corresponding area user identification and an authentication code stored in the table storage 5. An authentication code corresponding to an area user identification in the table storage 5 which coincides with the area user identification is validated with regard to the input authentication code, thereby authenticating an area user.
When an area user is authenticated, a sum of area sizes of already formed data fields is subtracted from a corresponding usable area size in the table storage 5, thereby calculating a remainder usable area of the corresponding area user.
When the remainder usable area size is equal to or larger than the demanded area size, the data field area acquiring portion 4 is operated.
When the vacant area in the IC card is equal to or larger than the demanded area size, the data field area acquiring portion 4 acquires an area in the vacant area, and thus additionally forms a data field.
Figure 5 is a flow chart for explaining the operation of the system shown in Fig. 4.
A_memory data field formation demand, a user identification, an authentication code, and an area size demand for the IC card are received from a terminal apparatus.
The CPU searches for an area user identification ~z9~
corresponding to the input area user identification in the table storage 5 (step Sl).
When no coincident identification i5 found, it is determined that a demander is not an authenticated area user, and an error indication is made.
For example, a non-response state is established for an external apparatus, or information indicating that registration is not permitted is indicated as a response signal.
If a coincident identification is found, an authentication code in the table storage corresponding to the identification is validated with regard to the input authentication code (step S2).
If the validation result is noncoincidence, it is determined that a demander is not an authenticated area user, and an error indication is made. However, when coincidence is established, it is determined that a demander is an authenticated area user, and the control advances to authentication of the area size (step S3).
Area user identifications in data fields in the IC
card are compared with the input area user identification so as to find a coincident data field (step S4).
Then, the CPU sums the area sizes of these data fields and derives the sum as a used area size with respect to the area user identification (step S5).
If the area has not been used, the sum is zero.
Next, the used area size is subtracted from a usable area size in the table storage corresponding to the area user identification, and the difference is compared with the input area size demand.
If the difference is smaller than the area size demand in the above comparison step, an error indication _: _ _ m is made since a vacant area-is not available (step S6).
If the difference is equal ~o or larger than the area size demand, the area size demand is compared with the area size of the vacant area in the IC card. If the area size demand is larger than the vacant area, an ~g~2~
error indication is made since the vacant area is not available (step S7).
If the area size demand is ~ual to or smaller than the vacant area size, a new data field area is acquired from the vacant area of the IC card, an area user identification and an area size are set, and a data field is additionally formed. Thus, the processing is ended ~step S8~.
As the area user identification, an identification of a service supplier or that for a group of service suppliers is used.
Figure 6 is a block diagram for supplementarily explaining the system of the present invention. That is, from another point of view, the system shown in Fi~. 4 can be considered as one having an arrangement shown in Fig. 6.
A unit for usin~ a memory accesses a use area registered in a unit for registration based on a demand for processing various services supplied from a contact.
A table storage stores an area size of a data field that can be assigned to a memory with respect to processing of various services, e.g., the number of bytes. ~he memory has a plurality of data fields. The memory has data fields corresponding to an area user who has already provided a service using this IC card or corresponding to the types of service processing.
Even if a given service is registered in advance in the table storage, if it has not been actually used yet, that is, if a card user does not wish to register the given service and does not register in a service company, no data field corresponding to the service is formed.
In a unit for permission, an area size demand of --new service-processing-supplied from an external apparatus through the contact is compared with a usable area size read out from the information storage table.
As a result of comparison, if the area size demand is equal to or smaller than the usable area size, data ~Z~c~2~8 corrssponding to an address space of a size corre-sponding to one of the area size demand and the usable area size, e.g., a start address and a byte length of a data field area, are stored in the unit for regis-tration, thus permitting the subsequent use.
When the IC card has vacant areas, some services may be additionally provided to the vacant areas in the card after card issuance.
The source which additionally provides a service must not be an arbitrary third party, but one of several limited companies, organizations, company groups, organization groups, or the like. ~lso, the data field area used must be limited. If a given service supplier is allowed to use any size of area, another would find it difficult to additionally provide a service. Therefore, it is desired that each service supplier be allowed to use only up to a predetermined size of area.
In a conventional system for acquiring a data field area, the data field area is additionally acquired based on the area size demand input from a terminal apparatus to an IC card and the data field information already formed in the IC card.
In the conventional system, data field formation demand input from a terminal apparatus can be accepted regardless of the demander, and the data field area, corresponding to the demanded area size is acquired in so far as there is a vacant data field area in the IC
card. In the conventional system~ therefore, there are problems that, if only a former of a data field obtains a right and approval for forming an area, a data field may be formed in the IC card by an unauthorized source, or the data field area in the IC card may be exclusively occupied by a specific service supplier, and there may be a disadvantage that, if an attempt is made to add an additional service to the IC card, there is no area vacant for such an additional service.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved system for data field area acquisition wherein a plurality of area user identifications and authentication codes and usable area size data are stored in an IC card upon issuance of the IC card. A
data field formation demand by a person other than an authenticated area user or a data field formation demand for an area larger than a predetermined size is rPjected, so the IC card can be protected from illegal data field formation.

The calculation of a remainder area for user authenticated by said area user authentication unit is carried out based on an input area size demand and information stored in the tble storage unit. Based on the cumulati~e result of the area user authentication and the calculation of the remainder area for the authenticated area user, acquisition of an additional data field area is carried out within a limit of usable area size.

DESCRIPTION OF THE PREFERRED EMBODIMEN~
Prior to a description o~ a preferred em~odiment of the present invention, an IC card as used both in the system of the present invention and a conventional system will be described. Figures 1 and 2 are for explaining an IC card. As shown in Fig. 1, an IC card has contacts, an integrated circuit module arranged beneath the contacts, and an area to be em~ossed.
Figure 2 shows a terminal apparatus electrically connected to the IC card, a program portion for requesting formation of a data field, and a transmission path through which an area user identification and an authentication code (AC code) designated by the program r - -and an-area--size~demand are transmitted to the IC card.
The IC card includes a CPU as a data processor, a memory, such as EPROM and/OR EEPROM, for storing input information, control information, and data fields, and a ROM for storing control programs. In addition, a plurality of metal ~ontacts for electrically contacting an external apparatus are provided on the surface or back of the car~.
Figure 3 shows an example of a conventional system for acquiring a data field area~ In Fig. 3, reference numeral 13' denotes a portion for inputting an area size demand; 81, 82, and 83, data fields already formed in an IC card; 80, an additionally acquired data field; and 4', a portion for acquiring data field data.
In the conventional system shown in Fig. 3, a data field formation demand sent from a terminal apparatus is accepted regardless of the requester when the requester is authenticated by general authentication such as a personal identification number and an authentication code for an IC card. Thus, a data field area corre-sponding to an area size demand is acquired by the portion 4' as long as the IC card has a vacant area. ~n this manner, a data field is additionally formed.
A system for data field area acquisition in an IC
card for plural services according to an embodiment of the present invention will now be described with reference to Figs. 4 and S. Figure 4 shows a system according to an embodiment of the present invention.
The system of Fig. 4 includes an area user identification inputting portion 11, an authentication code inputting portion 12, a portion 13 for inputting an area size demand, area user identifications 51, area user authentication codes 52, usable area sizes 53, and a storage 5 for a table for data field control, con-stituted by the plurality of area user identifications51, the authentication codes 52, and the usable area sizes 53.
~ _ s ~~ - - -The system of Fig. 4 also includes memories for area user identifications 61, 62, and 63 corresponding to the data fields, area size information 71, 72, and 73 corresponding to the data fields, data fields 81, 82, and 83, an area user identification 60 corresponding to 9~
a data field 80 to be additionally acquired, an area size information 7~ of the data field to be additionally acquired, and an additionally acquired data field 80.
- The system of Fig. 4 further includes an area user authentication portion ~, a portion 3 for calculating a remainder area for an authenticated area user; and a portion 4 for additionally acquiring a data field area.
The operation of the system shown in Fig. 4 will now be described. The authenticating portion 2 compares an input area user identification from the portion 11 and an input authentication code from the portion 12 with a corresponding area user identification and an authentication code stored in the table storage 5. An authentication code corresponding to an area user identification in the table storage 5 which coincides with the area user identification is validated with regard to the input authentication code, thereby authenticating an area user.
When an area user is authenticated, a sum of area sizes of already formed data fields is subtracted from a corresponding usable area size in the table storage 5, thereby calculating a remainder usable area of the corresponding area user.
When the remainder usable area size is equal to or larger than the demanded area size, the data field area acquiring portion 4 is operated.
When the vacant area in the IC card is equal to or larger than the demanded area size, the data field area acquiring portion 4 acquires an area in the vacant area, and thus additionally forms a data field.
Figure 5 is a flow chart for explaining the operation of the system shown in Fig. 4.
A_memory data field formation demand, a user identification, an authentication code, and an area size demand for the IC card are received from a terminal apparatus.
The CPU searches for an area user identification ~z9~
corresponding to the input area user identification in the table storage 5 (step Sl).
When no coincident identification i5 found, it is determined that a demander is not an authenticated area user, and an error indication is made.
For example, a non-response state is established for an external apparatus, or information indicating that registration is not permitted is indicated as a response signal.
If a coincident identification is found, an authentication code in the table storage corresponding to the identification is validated with regard to the input authentication code (step S2).
If the validation result is noncoincidence, it is determined that a demander is not an authenticated area user, and an error indication is made. However, when coincidence is established, it is determined that a demander is an authenticated area user, and the control advances to authentication of the area size (step S3).
Area user identifications in data fields in the IC
card are compared with the input area user identification so as to find a coincident data field (step S4).
Then, the CPU sums the area sizes of these data fields and derives the sum as a used area size with respect to the area user identification (step S5).
If the area has not been used, the sum is zero.
Next, the used area size is subtracted from a usable area size in the table storage corresponding to the area user identification, and the difference is compared with the input area size demand.
If the difference is smaller than the area size demand in the above comparison step, an error indication _: _ _ m is made since a vacant area-is not available (step S6).
If the difference is equal ~o or larger than the area size demand, the area size demand is compared with the area size of the vacant area in the IC card. If the area size demand is larger than the vacant area, an ~g~2~
error indication is made since the vacant area is not available (step S7).
If the area size demand is ~ual to or smaller than the vacant area size, a new data field area is acquired from the vacant area of the IC card, an area user identification and an area size are set, and a data field is additionally formed. Thus, the processing is ended ~step S8~.
As the area user identification, an identification of a service supplier or that for a group of service suppliers is used.
Figure 6 is a block diagram for supplementarily explaining the system of the present invention. That is, from another point of view, the system shown in Fi~. 4 can be considered as one having an arrangement shown in Fig. 6.
A unit for usin~ a memory accesses a use area registered in a unit for registration based on a demand for processing various services supplied from a contact.
A table storage stores an area size of a data field that can be assigned to a memory with respect to processing of various services, e.g., the number of bytes. ~he memory has a plurality of data fields. The memory has data fields corresponding to an area user who has already provided a service using this IC card or corresponding to the types of service processing.
Even if a given service is registered in advance in the table storage, if it has not been actually used yet, that is, if a card user does not wish to register the given service and does not register in a service company, no data field corresponding to the service is formed.
In a unit for permission, an area size demand of --new service-processing-supplied from an external apparatus through the contact is compared with a usable area size read out from the information storage table.
As a result of comparison, if the area size demand is equal to or smaller than the usable area size, data ~Z~c~2~8 corrssponding to an address space of a size corre-sponding to one of the area size demand and the usable area size, e.g., a start address and a byte length of a data field area, are stored in the unit for regis-tration, thus permitting the subsequent use.
