store the device data in, among a plurality of storage corresponding to different levels of use frequency, one of the plurality of storage that corresponds to the use frequency estimated by the processor.

2. The data collection server according to claim 1 , wherein

the processor estimates the use frequency of the device data to be predetermined use frequency corresponding to the meaning which is identified.

3. The data collection server according to claim 1 , wherein

the processor estimates the use frequency of the device data based on acquisition frequency of device data having the same meaning as identified by the processor.

4. The data collection server according to claim 1 , wherein the processor is further configured to

receive, from the device, information about the use frequency associated with the device data, and

estimate the use frequency of the device data to be the use frequency indicated by the received information about the use frequency.

5. The data collection server according to claim 1 , wherein the processor is further configured to

receive personal information associated with the device, and

store the personal information which is received in a personal information storage to store personal information.

6. The data collection server according to claim 1 , wherein the processor is further configured to:

retrieve the device data stored in the one of the plurality of storage; and

transmit the device data which is retrieved and supplementary information including information about the use frequency of the device data to a data utilization server as circulation data.

7. The data collection server according to claim 6 , wherein the processor is further configured to:

generate comprehensive supplementary information relating to a data set including a plurality of pairs of the device data and the supplementary information,

wherein the processor transmits the data set and the comprehensive supplementary information to the data utilization server as the circulation data.

8. The data collection server according to claim 7 , wherein the processor is further configured to:

generate a sales catalog of the data set based on the comprehensive supplementary information,

transmit the sales catalog to the data utilization server,

receive a request for the circulation data corresponding to the sales catalog from the data utilization server, and

transmit the circulation data to the data utilization server in response to the request from the data utilization server.

9. The data collection server according to claim 6 , wherein the processor is further configured to

transmit a request for certifying authenticity of the device data and information for certifying the authenticity to a certification server, and

receive a certificate certifying the authenticity of the device data from the certification server.

10. A data utilization server, comprising:

a processor coupled to a memory and configured to:

receive, from a data collection server, circulation data including device data acquired from a device and supplementary information including information about use frequency of the device data, wherein the supplementary information further includes information about a meaning of the device data based on a device type of the device indicated in the device data and based on details indicating device operation and/or device status of the device included in the device data; and

store the device data included in the circulation data received by the processor in, among a plurality of storage corresponding to different levels of use frequency, one of the plurality of storage that corresponds to the use frequency indicated by the circulation data.

11. The data utilization server according to claim 10 , wherein

the circulation data further includes personal information associated with the device, and

the processor is further configured to store the personal information associated with the device and included in the circulation data which is received in a personal information storage to store personal information.

12. A device for communicating with a data collection server, the device comprising:

a processor coupled to a memory and configured to:

generate device data;

identify a meaning of the device data based on a device type of the device indicated in the device data and based on details indicating device operation and/or device status of the device included in the device data,

estimate use frequency of the device data generated by the processor as corresponding to the meaning identified by the processor; and

transmit, to the data collection server, the device data and supplementary information including information about the use frequency.
