<p><P>PROBLEM TO BE SOLVED: To provide a file management system capable of preventing a file from being illegally taken out. <P>SOLUTION: After receiving a file from a terminal apparatus 5, a master server program 30 generates dispersion information concerned with the file and stores the dispersion information in a dispersion information storage part 316 which is achieved by a non-volatile memory. The master server program 30 divides the file to be stored into the prescribed number of files in each prescribed file size on the basis of the dispersion information and transmits the divided files to slave servers 4. The transmitted divided files are stored in respective slave servers 4. When a file reference request is received from the terminal apparatus 5, the master server program 30 collects the divided files from the slave servers 4 on the basis of the dispersion information concerned with the file, combines the divided files to restore the original file, and transmits the restored file to the terminal apparatus 5. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
