Abstract

An information processing apparatus includes a memory and a processor. The memory is configured to store first authority information, the first authority information including information for specifying a hardware resource, the first authority information being used for determining whether or not to permit operation of the hardware resource. The processor is coupled to the memory. The processor is configured to perform accepting a request for transmitting the first authority information to a destination apparatus, determining, in response to the request, whether second authority information is set or not, the second authority information being used for making a copy feasibility determination of the first authority information, transmitting the first authority information to the destination apparatus together with the second authority information when the second authority information is set and deleting the second authority information set in the transmitted first authority information.

Claims

1. An information processing apparatus comprising:

a memory configured to store first authority information, the first authority information including information for specifying a hardware resource and a serial number for identifying the first authority information, the first authority information being used for determining whether or not to permit operation of the hardware resource; and

a processor coupled to the memory and the processor configured to perform;

accepting a request for transmitting the first authority information to a destination apparatus;

determining, in response to the request, whether the memory stores second authority information including the serial number of the first authority information;

transmitting the first authority information to the destination apparatus together with the second authority information when the memory stores the second authority information including the serial number of the first authority information; and

deleting the second authority information including the serial number of the transmitted first authority information.

2. The information processing apparatus according to claim 1, wherein the processor executes the deleting when receiving reception complete notification transmitted from the destination apparatus permitting an operation of the hardware resource specified by the transmitted first authority information.

6. The information processing apparatus according to claim 1, wherein the information for specifying the hardware resource includes at least one of information for specifying a processor and information for specifying a memory.

3. An information processing apparatus comprising:

a memory; and

a processor coupled to the memory and the processor configured to perform;

receiving, from a source apparatus, first authority information including information for specifying a hardware resource and a serial number for identifying the first authority information and second authority information including the serial number of the first authority information, the first authority information being used for determining whether or not to permit operation of the hardware resource; and

permitting an operation of the hardware resource specified by the received first authority information when receiving, from the source apparatus, notification that second authority information including the serial number of the received first authority information is deleted from the source apparatus.

4. The information processing apparatus according to claim 3, wherein

at least one of the first authority information and the second authority information further includes apparatus information indicating an information processing apparatus enabled to use the first authority information, and

the processor permits the operation of the hardware resource specified by the received first authority information when the apparatus information indicates a self apparatus, the apparatus information being included in at least one of the received first authority information and the received second authority information.

5. The information processing apparatus according to claim 3, wherein

at least one of the first authority information and the second authority information further includes model information indicating a model of the information processing apparatus becoming an issuance target apparatus of the first authority information, and

the processor permits the operation of the hardware resource specified by the received first authority information when a model indicated by the model information is a model equal to a self apparatus or a higher-order model than the self apparatus, the model information being included in at least one of the received first authority information and the received second authority information.

7. An information processing system including a first information processing apparatus and a second information processing apparatus,

the first information processing apparatus comprising:

a first memory configured to store first authority information, the first authority information including information for specifying a hardware resource and a serial number for identifying the first authority information, the first authority information being used for determining whether or not to permit operation of the hardware resource; and

a first processor coupled to the first memory and the first processor configured to perform;

accepting a request for transmitting the first authority information to the second information processing apparatus;

determining, in response to the request, whether the first memory stores second authority information including the serial number of the first authority information;

transmitting the first authority information to the second information processing apparatus together with the second authority information when the first memory stores the second authority information including the serial number of the first authority information; and

deleting the second authority information including the serial number of the transmitted first authority information,

the second information processing apparatus comprising;

a second memory; and

a second processor coupled to the second memory and the second processor configured to perform;

receiving the transmitted first authority information and the second authority information; and

permitting an operation of the hardware resource specified by the received first authority information.

8. The information processing system according to claim 7, wherein

the second processor transmits reception complete notification to the first information processing apparatus when permitting the operation of the hardware resource specified by the received first information processing apparatus, and

the first processor executes the deleting when receiving the reception complete notification from the second information processing apparatus.

9. The information processing system according to claim 7, wherein

the first processor transmits deletion complete notification to the second information processing apparatus when completing the deleting, and

the second processor permits the operation of the hardware resource specified by the received first information processing apparatus when receiving the deletion complete notification.

10. The information processing system according to claim 7, wherein

at least one of the first authority information and the second authority information further includes apparatus information indicating an information processing apparatus enabled to use the first authority information, and

the second processor permits the operation of the hardware resource specified by the received first authority information when the apparatus information indicates a self apparatus, the apparatus information being included in at least one of the received first authority information and the received second authority information.

11. The information processing system according to claim 7, wherein

at least one of the first authority information and the second authority information further includes model information indicating a model of the information processing apparatus becoming an issuance target apparatus of the first authority information, and

the second processor permits the operation of the hardware resource specified by the received first authority information when a model indicated by the model information is a model equal to a self apparatus or a higher-order model than the self apparatus, the model information being included in at least one of the received first authority information and the received second authority information.

12. The information processing system according to claim 7, wherein the information for specifying the hardware resource includes at least one of information for specifying a processor and information for specifying a memory.
