Abstract

An information transmission device stores an identifier representing an information processing device connected to a network in association with an identifier representing a storage device used by the information processing device. When transmission of information is requested from the information processing device, the information transmission device specifies an identifier representing an information processing device. The information transmission device acquires an identifier representing a storage device stored in association with the specified identifier. The information transmission device transmits information on a request for transmission by the information processing device to the storage device represented by the acquired identifier.

Claims

1. An information transmission device comprising:

a storage unit that stores an identifier representing an information processing device connected to a network in association with an identifier representing a storage device used by the information processing device;

a processor to, when a notice requesting transmission of information is received from the information processing device, specify an identifier representing an information processing device that has transmitted the notice, to acquire an identifier representing a storage device stored in association with the specified identifier, and to control transmission of information on a request for transmission by the information processing device to the storage device represented by the acquired identifier acquired.

2. An information transmission device comprising:

a storage means for storing an identifier representing an information processing device connected to a network in association with an identifier representing a storage device used by the information processing device;

a specification means for, when a notice requesting transmission of information is received from the information processing device, specifying an identifier representing an information processing device that has transmitted the notice;

an acquisition means for acquiring an identifier representing a storage device stored in association with the identifier specified by the specification means; and

a transmission means for transmitting information on a request for transmission by the information processing device to the storage device represented by the identifier acquired by the acquisition means.

3. The information transmission device according to claim 2,

wherein the transmission means determines whether or not the device itself is storing information on a request for transmission by the information processing device, acquires the information from an external information processing device when it is determined that the device itself is not storing the information on a request for transmission by the information processing device, and transmits the acquired information to the storage device represented by the identifier acquired by the acquisition means.

4. The information transmission device according to claim 2, further comprising:

an encryption key storage means for storing the identifier representing the information processing device in association with an encryption key used by the information processing device; and

an encryption key acquisition means for acquiring an encryption key stored in association with the identifier specified by the specification means from the encryption key storage means,

wherein the transmission means transmits information on a request for transmission by the information processing device and the encryption key acquired by the encryption key acquisition means to the storage device represented by the identifier acquired by the acquisition means.

5. A network system comprising:

an information transmission device that includes

a storage unit that stores an identifier representing an information processing device connected to a network in association with an identifier representing a storage device used by the information processing device,

an encryption key storage unit that stores the identifier representing the information processing device in association with an encryption key used by the information processing device,

a specification unit that, when transmission of information is requested from the information processing device, specifies an identifier representing an information processing device that has requested transmission of the information,

an acquisition unit that acquires an identifier representing a storage device stored in association with the identifier specified by the specification unit,

an encryption key acquisition unit that acquires an encryption key stored in association with the identifier specified by the specification unit from the encryption key storage unit, and

a transmission unit that transmits information on a request for transmission by the information processing device and the encryption key acquired by the encryption key acquisition unit to the storage device represented by the identifier acquired by the acquisition unit; and

a storage device that includes

an encryption information storage unit that, when the information and the encryption key are received from the information transmission device, stores the received information using the received encryption key.

6. An information transmission method performed in an information transmission device that includes a storage unit, the storage unit storing an identifier representing an information processing device connected to a network in association with an identifier representing a storage device used by the information processing device, the information transmission method comprising:

specifying, when a notice requesting transmission of information is received from the information processing device, an identifier representing an information processing device that has transmitted the notice;

acquiring an identifier representing a storage device stored in association with the identifier specified at the specifying; and

transmitting information on a request for transmission by the information processing device to the storage device represented by the identifier acquired at the acquiring.

7. A computer-readable, non-transitory medium storing an information transmission program causing a computer to execute a process, the computer including a storage unit that stores an identifier representing an information processing device connected to a network in association with an identifier representing a storage device used by the information processing device, the process comprising:

specifying, when a notice requesting transmission of information is received from the information processing device, an identifier representing an information processing device that has transmitted the notice;

acquiring an identifier representing a storage device stored in association with the identifier specified at the specifying; and

transmitting information on a request for transmission by the information processing device to the storage device represented by the identifier acquired at the acquiring.
