Summary:PROBLEM TO BE SOLVED: To verify normality/integrity of a file, by adding a module for verifying normality/integrity of the file input/output in a file system. SOLUTION: The file system 7 instructs to write a certain file into a physical device 2. A data integrity velification module 4 calculates a first hash value of the file. An operating system 1 adds the first hash value to the file, and outputs the file with the first hash value added thereto to the physical device 2. The physical device 2 stores the file with the first hash value added thereto. COPYRIGHT: (C)2009,JPO&INPIT
