Patent Searching and Data


Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/021715
Kind Code:
A1
Abstract:
The value of input data D, said value being based on data value examination criterion C, is determined by a secure calculation in which the data D and the data value examination criterion C are in no case disclosed to each other. The secure calculation is executed without a data providing device disclosing the input data D to a data collecting device and without the data collecting device disclosing the data value examination criterion C to the data providing device. The data providing device generates, by the secure calculation, distributed information rp representing one data value index-value that is the calculated value of data value calculation functions f (D, C) of the input data D, and calculates a data value index-value by computation of the generated distributed information rp with other distributed information rc representing one data value index-value that was received from the data collecting device.
