Patent number: 7734598Abstract: A computer-readable recording medium having recorded a hash-value generation program for calculating a hash value within a shorter period of processing time. When a target disk is specified for hash value calculation, a segment division block divides the target disk into fixed-length segments. A first hash-value calculation block applies a one-way hash function to all data in each segment to calculate a per-segment hash value. A second hash-value calculation block arranges the per-segment hash values in a segment order corresponding to the order of the data stored on the target disk and applies the one-way hash function again to the arranged per-segment hash values to calculate a total hash value. The hash value calculated in this manner is defined as a hash value of the target disk.Type: GrantFiled: August 2, 2006Date of Patent: June 8, 2010Assignee: Fujitsu LimitedInventors: Yasuo Noguchi, Kazutaka Ogiwara, Masahisa Tamura, Yoshihiro Tsuchiya, Tetsutaro Maruyama, Riichiro Take
