Method and apparatus for managing resources, and computer-readable storage medium for computer program

A method for managing a resource, the method comprising:

• a step of providing a first portable recording medium recording, thereon, a first key;
• a step of providing a user with a second portable recording medium;
• a step of storing, in a key storage portion, the first key that is currently valid;
• a step of generating a second key corresponding to the first key recorded on the first portable recording medium, and recording the second key and the first key that corresponds to the second key onto the second portable recording medium when the first portable recording medium and the second portable recording are set, for user registration, on a reader/writer during a predetermined period;
• and
• a step of allowing the user to access the resource if the second key is read out from the second portable recording medium in order for the user to use the resource and the first key corresponding to the second key is stored in the key storage portion, and forbidding the user to access the resource if the second key is read out from the second portable recording medium in order for the user to use the resource and the first key corresponding to the second key is not stored in the key storage portion.

An apparatus for managing a resource, the apparatus comprising:

• a user usage data generation portion that generates data to include a user identification code for identifying a user and a registration code for registering the user that is associated with the user identification code, when the user identification code and the registration code are read out from a first portable recording medium of the user and a second portable recording medium respectively during a predetermined period;
• a user storage portion which stores the generated data;
• and
• a control portion that forbids the user to access the resource if the user identification code is read out from the first portable recording medium in order for the user to use the resource and the user identification code thus read out is not stored in generated data of the user storage portion.

An apparatus for managing a resource, the apparatus comprising:

• a registration process portion that, when a first portable recording medium storing, thereon, a first key and a second portable recording medium of a user are set, for registering the user, on a reader/writer during a predetermined period, generates a second key corresponding to the first key and records the second key and the first key in association with each other onto the second portable recording medium;
• a key storage portion that stores the first key that is currently valid;
• and
• a control portion that allows the user to access the resource if the second key is read out from the second portable recording medium in order for the user to use the resource and the first key corresponding to the second key is stored in the key storage portion, and forbids the user to access the resource if the second key is read out from the second portable recording medium in order for the user to use the resource and the first key corresponding to the second key is not stored in the key storage portion.

A non-transitory computer-readable storage medium storing thereon a computer program used in a computer for managing a resource, the computer program causing the computer to perform:

• a registration process of generating data associating a user identification code for identifying a user and a registering code for registering the user, when the user identification code and the registration code are read out from a first portable recording medium of the user and a second portable recording medium respectively during a predetermined period;
• and
• a storing process of storing the generated data;
• an access control process of forbidding the user to access the resource if the user identification code is read out from the first portable recording medium in order for the user to use the resource and the user identification code thus read out is not stored in the generated data of the user storage portion.

A non-transitory computer-readable storage medium storing thereon a computer program used in a computer for managing a resource, the computer program causing the computer to perform:

• a user registration process of, when a first portable recording medium storing, thereon, a first key and a second portable recording medium of a user are set, for registering the user, on a reader/writer during a predetermined period, generating a second key corresponding to the first key and recording the second key and the first key that corresponds to the second key in association with each other onto the second portable recording medium;
• a key registration process of storing, in a key storage portion, the first key that is currently valid;
• and
• an access control process of allowing the user to access the resource if the second key is read out from the second portable recording medium in order for the user to use the resource and the first key corresponding to the second key is stored in the key storage portion, and forbidding the user to access the resource if the second key is read out from the second portable recording medium in order for the user to use the resource and the first key corresponding to the second key is not stored in the key storage portion.
