Information processing device, information processing system, information processing method, and program

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 nocase 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.

Description

technical field [0001] The present disclosure relates to an information processing device, an information processing system, an information processing method, and a program. More specifically, the present disclosure relates to an information processing device, an information processing system, an information processing method, and a program for acquiring an operation result to which security data is applied without disclosing security data whose distribution is restricted. Background technique [0002] In recent years, communication is actively performed via a network such as the Internet, and the amount of communication data is increasing. [0003] These types of communication data include various types of communication information such as personal information of a large number of users, location information and also commodity transaction information. [0004] These types of communications also include, for example, user information that the user does not wish to disclose,...

AI Technical Summary

Problems solved by technology

In addition, for the collector, there is the following problem: every time the data is used, a query needs to be sent to the provider, which requires communication costs

[0018] Although this patent document 3 includes a system that determines the value of user information, even in the case of utilizing this system, since the data provider needs to provide the data to the data collector at a time, there are problems of the risk of data being transferred and privacy Increased Risk of Information Leakage
