Abstract: A method and system for processing information. An apparatus divides target information into N pieces of divided data using a secret sharing scheme in which a predetermined number (K) of pieces of the N pieces of divided data is required to restore the target information, wherein N>K. The apparatus is an information processing device or an external storage device. The apparatus selects M pieces from the N pieces (K<M<N). After selecting the M pieces, the M pieces are stored in the external storage device which limits a totality of pieces of the N pieces being stored on the external storage device to the M pieces. After storing the M pieces, the target information is restored from at least K pieces of the N pieces after which D pieces of the M pieces in the external storage device are destroyed (D>M?K).
