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.

Abstract: A high-speed automatic image drawing apparatus divides a three-dimensional object to draw into primitives that can be drawn at a high speed, and draws an image of the object according to the primitives by gradually changing lightness and chromaticity. The image thus provided has a material-like impression. The apparatus comprises a primitive forming unit for dividing the three-dimensional object to draw into predetermined shapes and forming primitives according to the shapes, and a grading unit for drawing the object according to the primitives by gradually changing lightness and chromaticity. In response to a request of drawing a three-dimensional object, the primitive forming unit divides the object into predetermined shapes, and forms primitives for the shapes. Thereafter, the grading unit draws an image of the object according to the primitives by gradually changing lightness and chromaticity.

Abstract: A multiprocess input system includes a first process execution part for processing input data, a second process execution part for processing the input data, and a third process execution part for distributing the input data to the first and second process execution part.
