Abstract: Value of data D based on a data value examination criterion C is determined through secure calculation without input data D and the data value examination criterion C being disclosed to each other. Secure calculation is executed without a data providing device disclosing the input data D to a data collecting device, and further, without a data collecting device disclosing the data value examination criterion C to the data providing device. The data providing device generates one piece of distributed information rp of a data value index value which is a calculation value of a data value calculation function f(D, C) of the input data D through secure calculation and calculates the data value index value through operation of the generated distributed information rp and another piece of distributed information rc of the data value index value received from the data collecting device.
