Abstract
An information processing apparatus includes a processor configured to receive, respectively from a plurality of external devices, plural pieces of encrypted data encrypted with a random number sequence. The processor generates parity data by using the received plural pieces of encrypted data. The processor stores the generated parity data in a memory. The processor receives a restoration request for restoring first encrypted data from a first external device among the plurality of external devices. The processor receives, respectively from one or more second external devices among the plurality of external devices other than the first external device, one or more pieces of second encrypted data among the plural pieces of encrypted data other than the first encrypted data. The processor restores the first encrypted data by using the received one or more pieces of second encrypted data and the parity data stored in the memory.
