ABSTRACT:
An information processor has an information dispersing function, a dividing unit for dividing a first data (DT0) into n pieces of disperse information, and executing secret sharing scheme capable of restoring the first data (DT0) by using arbitrary k pieces (1<k<n) of disperse information out of the n pieces of disperse information, a first storage control unit for storing the arbitrary k pieces of disperse information generated by the dividing unit into plurality of portable recording devices, an editing unit for reconstructing the first data (DT0) by using the k pieces of disperse information stored in the plurality of recording devices and editing the restored first data (DT0), a difference generating unit, after the dividing unit divides a second data which is post-data (DT1) originated in the restored first data into n pieces of post-edit disperse information, for calculating the difference between post-edit disperse information corresponding to the recording device and pre-edit disperse information which has been stored in the recording device, and a second storage control unit for storing, for each of the recording devices, the post-edit disperse information of the recording device and the difference corresponding to the other recording devices.
