<p><P>PROBLEM TO BE SOLVED: To accurately execute original verification. <P>SOLUTION: An original verification device 300, obtains signature data from a signature device 100, and obtains partial stream data and partial signature data from a segmenting device. The original verification device 300 gives continuous serial numbers to each TC packet included in the partial stream data, then divides the partial stream data into each classification, and obtains a hash value for each unit divided while including the serial number, thereby executing original verification. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
