Abstract

Abstract An IC card issue system of the present invention issues IC cards (5), each having a data memory (52) and a control element (51), to individuals by respectively writing, in the data memories of the respective portable storage media, issue data common to the individuals and issue data which differ individually. The system includes a storage section (2) for storing an issue data file (2a) constituted by a common data group (12) as a set of issue data common to each person, a personal data group (13) as a set of issue data which differ individually, and attribute information (11). A read section (6) for sequentially reading out the issue data from the common data group (12) or from the personal data group (13) in the storage section (2) on the basis of discrimination signs (23) in the attribute information (11) stored in the storage section (2), and a write section (6) for writing the issue data read out by the read section (6) in the data memory of the IC card (5). Each of the discrimination signs represents that corresponding issue data is common data or personal data, and values each indicating a specific location of corresponding issue data in the common data group or in the personal data group.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 152 words
A storage medium issue system characterized by comprising: means (2) for storing an issue data file (2a) including a common data section (12) for storing common data which is common to a plurality of storage media (5), a plurality of individual data sections (13) for storing personal data, each personal data being specific to each of the storage media (5), and an attribute data section (11) which indicates a location of data (12, 13) in said issue data file (2a); first reading means (1) for reading out the location data in said issue data file; second being means (1) for reading out the common data and the personal data in said issue data file in accordance with the location data read out by said first reading means; and means (1, 6) for writing the common data and the personal data, read out by said second reading means, to the storage media (5).
Claim 2
Dependent Claim 37 words
A system according to claim 1, characterized in that said attribute data section (11) includes: means for holding first information (21) indicating an order of issue data for the reading by said first and second reading means.
Claim 3
Dependent Claim 45 words
A system according to claim 2, characterized in that said attribute data section (11) includes: means for holding second information (22) indicating a location of a storage area of said common data section (12) and said individual data section (13) in said storing means (2).
Claim 4
Dependent Claim 36 words
A system according to claim 3, characterized in that said attribute data section (11) includes: means for holding third information (23) discriminating a kind of said common data section (12) and said individual data section (13).
Claim 5
Dependent Claim 42 words
A system according to claim 4, characterized in that said issue data file (2a) includes: means for holding fourth information (24) indicating the location of said common data section (12) and said individual data section (13) in said issue data file (2a).
Claim 6
Dependent Claim 40 words
A system according to claim 5, characterized in that said issue data file (2a) includes: means for holding fifth information (25) instructing whether or not a coded password (50th) contained in said individual data section (13) is to be decoded.
Claim 7
Dependent Claim 27 words
A system according to claim 1, characterized in that said storage media include IC cards (5) each of which comprises a microcomputer (51) and a memory (52).
Claim 8
Dependent Claim 70 words
A system according to claim 7, characterized in that said second reading means (1) includes: means (1) for reading the common data section (12) from said issue data file (2a) so as to commonly write into each memory (52) of said IC cards (5); and means (1) for sequentially reading the individual data section (13) so as to individually write into the respective memory (52) of said IC cards (5).
Claim 9
Dependent Claim 96 words
A system according to claim 1, characterized by further comprising: means (8) for providing an issuer key; means (1) for comparing a given password with said issuer key, and preventing the system from issuing the IC cards (5) if the password does not match the issuer key (ST2 to ST6 no); means (1) for performing a storage medium issuing operation (ST8 to ST44) when said password matches said issuer key (ST2 to ST6 yes); and means (1, 6) for transferring the issue data file (2a) to the storage medium (5) during the storage medium issuing operation.
Claim 10
Dependent Claim 69 words
A system according to claim 9, characterized by further comprising: means (8) for providing a decode key; means (1) for decoding a coded personal data (50th) contained in said individual data section (13) in accordance with said decode key; and means (1) for performing the storage medium issuing operation (ST8 to ST44), using the decoded personal data (50th), when said password matches said issuer key (ST2 to ST6 yes).
