Abstract
The present invention improves data transmission safety and data transfer rate, and reduces an increase in costs when doing so. A map management unitmanages a map which defines a prescribed rule for dividing pseudorandom number data into two. On the basis of the rule defined by the map, a division unitgenerates data obtained by dividing the pseudorandom number data into two as vertically irregular mapping input data and horizontally irregular mapping input data. A vertically irregular mapping unitgenerates data obtained by subjecting the vertically irregular mapping input data to irregular mapping processing as vertical base reference point data. A horizontally irregular mapping unitgenerates data obtained by subjecting the horizontally irregular mapping input data to irregular mapping processing as horizontal base reference point data. A base reference point information generation unitdecides on one base on the basis of the vertical base reference point data and the horizontal base reference point data.
