Recording medium, recording medium reading/writing apparatus, and method of using recording medium
First Claim
1. A recording medium, comprising:
- a verification information area configured to record a biometric datum; and
a public organization information area configured to record individual information which is able to be written or read by either a first manner or a second manner, the first manner using an encryption key and an encryption algorithm without using the biometric datum, the second manner using the biometric datum without using the encryption key or the encryption algorithm,wherein information written to the public information area by usage of the biometric datum can be read from the public information area by either usage of the first manner or the second manner, andwherein information written to the public information area by usage of the encryption key and encryption algorithm can be read from the public information area by either usage of the first manner or the second manner.

Abstract
The current society can be referred to as a card society, since people can use various types of cards for a variety of applications. However, card users must always carry a number of cards depending upon the application, and must use different cards according to the purpose, which can bother such users. A memory of an IC chip of an IC card includes a fingerprint information area to verify the identity of a card owner, a personal information area in which personal information of the card owner is classified and recorded with different security levels set up, a company information area in which each company writes information of the company using an “encryption key” unique to the company, and a public organization information area in which each public organization writes information of the public organization using an “encryption key” unique to the public organization.

11. A system comprising:
-
a sensor portion configured to read a first biometric datum of a first individual and a second biometric datum of a second individual; a first information portion configured to record a third biometric datum and a fourth biometric datum, the third biometric datum corresponding to the first biometric datum, the fourth biometric datum corresponding to the second biometric datum; a verification portion configured to directly compare the first biometric datum and the third biometric datum and to directly compare the second biometric datum and the fourth biometric datum; and a second information portion configured to record a first information, the first information being retrieved if the first biometric datum and the third biometric datum are judged as equal and the second biometric datum and the fourth biometric datum are judged as equal. - View Dependent Claims (12, 13, 14, 15, 16, 17)
