PROBLEM TO BE SOLVED: To reduce possibility that data created in an enterprise leak from the inside and outside of the enterprise.SOLUTION: A secrete dispersion system includes: a data supply part 12 for supplying data under edition stored in a volatile memory 11 in the case of creating data by a terminal 10 to a storage controller 20 as necessary; and a secrete dispersion processing part 22 for performing secrete dispersion of the data under edition supplied from the terminal 10, and for allowing a plurality of storage devices to store the data subjected to secrete dispersion in the storage controller 20. The data created by the controller 10 are supplied from the volatile memory 11 to the storage controller 20 as necessary, and subjected to secrete dispersion, and stored in a plurality of external storage devices in a dispersed manner. Thus, even when a partial division data leak, the original information itself is prevented from leaking, and when the power supply of the terminal 10 is turned off, the data are deleted from the volatile memory 11, and the data are prevented from remaining in the terminal 10.SELECTED DRAWING: Figure 2 |
