    Abstract: PROBLEM TO BE SOLVED: To prevent leakage of a parameter with high secrecy in a distributed computing system. SOLUTION: This distributed computing system for performing a plurality of partial computing operations is provided with a parameter storage means storing a parameter set constructed of a plurality of parameters, a conversion means converting a result of the partial computing operation and a linear parameter having a linearity into conversion parameters in each of a plurality of parameter sets, and a transmission means associating each of the converted parameter sets with parameter identification information about the parameter set and transmitting them for making a plurality of computing processors operate a plurality of partial computing operations. The distributed computing system is also provided with a conversion ratio storage means storing a conversion ratio of the parameter, a conversion ratio search means searching the conversion ratio matching the parameter identification information, and a reverse conversion output means generating results of the partial computing operation by multiplying the computing results by the reciprocal of the conversion ratio and outputting a pair of partial computing results.

    Abstract: PROBLEM TO BE SOLVED: To provide high durability against elimination or change of hidden message information by hiding medium information into message information in a frequency space and to keep hidden message information effectively even when signal processing using a frequency filter is executed. SOLUTION: In order to hide message information (m) in medium information M, these information are frequency-converted to obtain those frequency spectra f1 , f2 . Then an area including a characteristic frequency component denoting a characteristic of the message information (m) in a real space is extracted from the frequency spectrum f2 of the message information (m) as a basic area B. Regarding the basic area B, n-sets of copies are generated and n-sets of the copies are arranged dispersedly in the frequency space and the other frequency components are set to zero to generate a frequency spectrum f3 as intermediate information. Finally the frequency spectrum f3 and the frequency spectrum f1 are added and the result is frequency-converted inversely to hide the message information (m) into the medium information M.

    Abstract: PURPOSE: To shorten the boring route designing by displaying the arrangement of holes arranged along a route and the order of boring by binary vectors, respectively, and conforming all the binary vectors by a regular transformation matrix to determine the order of boring. CONSTITUTION: The format information of boring created by an engineering design system 1 is supplied to a boring order determination system 2, and the information of boring order is transmitted to a boring machine 3, whereby a printed wiring board is bored. At this time, it is checked whether all holes are connected to other holes or not in the boring order determination system 2, the order of boring of the holes within the corresponding section is determined every connecting section when the connection of holes is judged, and the entire order is then determined. In the determination of the order within the connecting section, the order of boring is expressed by binary with the hole on one end as the first hole and the hole on the other end as the N-th hole, and conformed by a regular transformation matrix to determine the order of boring.
