Portable storage medium and portable storage medium issuing system
First Claim
1. A portable storage medium issuing system for writing plural issuing data into storing regions of a portable storage medium, comprising:
- means for storing plural secret data;
first collating means for collating input secret data with the secret data stored in the storing means;
collated result storage means for storing which secret data of plural secret data has been collated and agreed with secrete data stored in the storage means based on the collating result of the first collating means;
collating condition storage means for storing plural issuing data and conditions of secret data, which are set corresponding to each of the plural issuing data and require the collation before writing into the portable storage medium, as collating conditions;
comparing means for comparing the collating conditions stored in the collating condition storage means with the collated status stored in the collated result storage means; and
writing means for writing issuing data in which this collating conditions are set in storing regions in the portable storage means when the collated status satisfies the collating conditions based on the result of comparison of the comparing means.

Abstract
A portable storage medium issuing system writes plural issuing data in storing regions in a portable storage medium. The system includes a first memory to store plural secret data, a second memory to collate input secret data with the secret data stored in the first memory and stores a secret data out of plural secret data, which is collated and agreed with the secret data stored in the first memory based on the collated result, a third memory to store the plural issuing data and secret data which has been set corresponding to each of plural issuing data and requires the collation before writing into the portable storage medium as collating conditions. The collating condition stored in the third memory is compared with the collated status stored in the second memory. When the collated status satisfies the collating condition based on the result of this comparison, the issuing data in which the collating condition has been set in the storing region is written in the portable storage medium.

4. A portable storage medium which has plural storing regions in which plural issuing data are written, comprising:
-
storage means for storing plural secret data; collating means for collating input secret data with the secret data stored in the storage means; collated result storage means for storing which secret data out of plural secret data has been collated and agreed based on the result of collation of the collating means; collating condition storage means for storing secret data condition which has been set corresponding to each of the plural storing regions and requires the collation before writing issuing data into the storing region as the collating condition; comparing means for comparing the collating condition stored in the collating condition storage means with the collated status stored in the collated result storage means; and writing means for writing issuing data supplied from an issuing system into a storing region wherein the collating condition has been set when the collated status satisfies the collating condition based on the result of comparison of the comparing means. - View Dependent Claims (5)

6. A portable storage medium issuing method for writing plural issuing data into storing regions of a portable storage medium, comprising:
-
first step of storing plural secret data in a storage means; second step of collating input secrete data with the secret data stored in the storage means; third step of storing secrete data out of plural secret data that has been collated and agreed based on the collated result by the second step; fourth step of storing the secret data condition which has been set corresponding to each of plural issuing data and requires the collation before writing into the portable storage medium as the collating condition; fifth step of comparing the collating condition stored in the fourth step with the collated status stored in the third step; and sixth step of writing the issuing data with the collating condition set in the storing regions in the portable storage medium when the collated status satisfies the collating condition based on the result of comparison in the fifth step. - View Dependent Claims (7, 8)
