Abstract
Abstract A system for permitting access to a data field area in an IC card for multiple services using an individual card holder identification number for each of a plurality of data fields (61, 62, 63) or for each group of data fields. Data field identification information (11), a personal identification number (12), access qualification information (13), and an authentication code (14) are supplied to the IC card before an execution of an access to the data field. An authentication is made (in 32, 33) between the personal identification number and the authentication code stored in identification number and the authentication code supplied to the IC card. Based on the result of authentication, an access to the data field area (61, 62 or 63) to which access is requested is permitted within the limit of the access right stored in the IC card (memories 51, 52, 53) corresponding to the access qualification information supplied to the IC card.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
A system for permitting access to a data field area in an IC card for multiple services using an individual card holder identification number for each of a plurality of data fields or for each groups of data fields, said system comprising: a plurality of data fields in the IC card; a sequence of data field selection means, a personal identification number authentication means, an authentication code validation means, and an access right selection means; an input means for inputting data field identification information, a personal identification number, access qualification information, and an authentication code; a data field access means and access request means; and storage means for storing information for data field control; comparisons between the information stored in said storage means and the information input through said input means being carried out, for authentication, validation, and selection; and based on the cumulative result of a selection of a data field, an authentication of a personal identification number, a validation of an authentication code, and a selection of an access right, access to a data field area to which access is requested is permitted within a limit of the selected access right.
Claim 2
Independent Claim
193 words
A system for permitting access to a data field area in an IC card for multiple services using an individual card holder identification number for each of a plurality of data fields or for each groups of data fields, said system comprising: a plurality of data fields in the IC card; a sequence of data field selection means, a personal identification number authentication means, an authentication code validation means, and an access right selection means; an input means for inputting data field identification information, a personal identification number, access qualification information, and an authentication code; a data field access means and access request means; and storage means for storing information for data field control; comparisons between the information stored in said storage means and the information input through said input means being carried out, for authentication, validation, and selection; and based on the cumulative result of a selection of a data field, an authentication of a personal identification number, a validation of an authentication code, and a selection of an access right, access to a data field area to which access is requested is permitted within a limit of the selected access right.
Claim 3
Dependent Claim
34 words
A system according to claim 1 wherein each memory for data field control stores data field identification information, a personal identification number, a plurality of authentication codes, and a plurality of access rights information.
Claim 4
Dependent Claim
28 words
A system according to claim 1, wherein the access qualification information input by said input means is an information for selecting an authentication code and an access right.
Claim 5
Dependent Claim
38 words
A system according to claim 1, wherein the access right information stored in the memories for data field control selected by the access qualification information is represented by one of the processes of reading, writing, deleting, and re-writing.
Claim 6
Dependent Claim
37 words
A system according to claim 1, wherein said personal identification number authentication means is operated based on signals from the data field selection means, the personal identification number input means, and the memories for data field control.
Claim 7
Dependent Claim
41 words
A system according to claim 1, wherein said authentication code validation means is operated based on signals from the personal identification number authentication means, the access qualification input means, the authentication code input means, and the memories for data field control.
Claim 8
Dependent Claim
35 words
A system according to claim 1, wherein said access right selection means is operated based on signals from the authentication code validation means, the access qualification input means, and the memories for data field control.
