Abstract

A data collection server includes a communicator, a use frequency estimator, and a data saver. The communicator receives device data from a device. The use frequency estimator estimates use frequency of the device data received by the communicator. The data saver stores the device data in, among a plurality of storage servers corresponding to different levels of use frequency, one of the plurality of storage servers that corresponds to the use frequency estimated by the use frequency estimator.

         17 . A data collection server, comprising:
 a receiver to receive device data from a device;   a use frequency estimator to estimate use frequency of the device data received by the receiver; and   a saver to 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 use frequency estimator,   wherein correspondence between each of the plurality of storage and use frequency is predetermined based on a storage fee and a retrieve fee.   
     
     
         18 . The data collection server according to  claim 17 , further comprising:
 a meaning identifier to identify a meaning of the device data received by the receiver,   wherein the use frequency estimator estimates the use frequency of the device data based on the meaning identified by the meaning identifier.   
     
     
         19 . The data collection server according to  claim 18 , wherein
 the use frequency estimator estimates the use frequency of the device data to be predetermined use frequency corresponding to the meaning identified by the meaning identifier.   
     
     
         20 . The data collection server according to  claim 18 , wherein
 the use frequency estimator estimates the use frequency of the device data based on acquisition frequency of device data having the same meaning as identified by the meaning identifier.   
     
     
         21 . The data collection server according to  claim 17 , wherein
 the receiver further receives, from the device, information about the use frequency associated with the device data, and   the use frequency estimator estimates the use frequency of the device data to be the use frequency indicated by the received information about the use frequency.   
     
     
         22 . The data collection server according to  claim 17 , wherein
 the receiver further receives personal information associated with the device, and   the saver further stores the personal information received by the receiver in a personal information storage to store personal information.   
     
     
         23 . The data collection server according to  claim 17 , further comprising:
 a data retriever to retrieve the device data stored in the one of the plurality of storage; and   a transmitter to transmit the device data retrieved by the data retriever and supplementary information including information about the use frequency of the device data to a data utilization server as circulation data.   
     
     
         24 . The data collection server according to  claim 23 , further comprising:
 a comprehensive supplementary information generator 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 transmitter transmits the data set and the comprehensive supplementary information to the data utilization server as the circulation data.   
     
     
         25 . The data collection server according to  claim 24  further comprising:
 a catalog generator to generate a sales catalog of the data set based on the comprehensive supplementary information, 
 wherein the transmitter transmits the sales catalog to the data utilization server, 
 the receiver receives a request for the circulation data corresponding to the sales catalog from the data utilization server, and 
 the transmitter transmits the circulation data to the data utilization server in response to the request from the data utilization server. 
 
     
     
         26 . The data collection server according to  claim 23 , wherein
 the transmitter further transmits a request for certifying authenticity of the device data and information for certifying the authenticity to a certification server, and   the receiver further receives a certificate certifying the authenticity of the device data from the certification server.   
     
     
         27 . A data utilization server, comprising:
 a receiver 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; and   a saver to store the device data included in the circulation data received by the receiver 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,   wherein correspondence between each of the plurality of storage and use frequency is predetermined based on a storage fee and a retrieve fee.   
     
     
         28 . The data utilization server according to  claim 27 , wherein
 the circulation data further includes personal information associated with the device, and
 the saver further stores the personal information associated with the device and included in the circulation data received by the receiver in a personal information storage to store personal information.
