<p><P>PROBLEM TO BE SOLVED: To estimate a content of transmission data without referring to data parts in packets when a data transmission device has divided the transmission data into units of packets and transmitted the divided pieces of transmission data. <P>SOLUTION: An information processing device estimates a content of transmission data transmitted from a data transmission device. The information processing device comprises: first information holding means which holds first feature information including a feature amount related to the data flow when the data transmission device holding a plurality of pieces of transmission data transmits the respective pieces of transmission data; second information holding means which holds second feature information including a feature amount related to the data flow when the data transmission device transmits any piece of transmission data; and means which collates the first feature information held by the first information holding means with the second feature information held by the second information holding means, and estimates transmission data transmitted by the data transmission device by using a result of the collation. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
