[0087] (Structure of information processing system)

[0088] figure 1 is a diagram showing a configuration example of a data providing system which is the information processing system according to the first embodiment of the present disclosure. The data providing system 100 includes a data providing device 10 and a data receiving device 20 . The data providing device 10 is a first information processing device used by a data provider. The data receiving device 20 is a second information processing device used by a data user.

[0089] The data providing device 10 and the data receiving device 20 are connected to each other through a network 1 such as a LAN (Local Area Network) and a WAN (Wide Area Network). The connection form of the data providing device 10 and the data receiving device 20 is not limited as long as the two devices 10 and 20 can send and receive data to and from each other.

[0090] In the data providing system 100, a plurality of data providing devices 10...

no. 2 approach

[0177] A data providing system according to a second embodiment of the present disclosure will be described. In the following description, explanation of the same structure and operation as those of the data providing system 100 according to the first embodiment will be omitted or simplified.

[0178] In the present embodiment, the following processing is performed to perform the frequency function calculation processing performed by the frequency function calculation unit. In this embodiment, the frequency function calculating unit sets predetermined attribute values ​​among the one or more attribute values ​​as non-target attribute values ​​not used for calculating the frequency function. In the present embodiment, the frequency function calculation unit also operates as a setting unit, and the frequency function calculation unit sets non-target attribute values. However, a block for setting non-target attribute values ​​may be additionally provided to the frequency functio...

no. 3 approach

[0198] A data providing system according to a third embodiment of the present disclosure will be described. Figure 14 is a schematic diagram for explaining an outline of the operation of the data providing system 300 according to the present embodiment. FIG. 15 is a diagram showing an example of a database possessed by the data providing device 310 and the data receiving device 320 according to the present embodiment.

[0199] In this embodiment, in the storage unit of the data receiving device 320 as an external device, a database as external data is stored. In the storage unit of the data providing device 310, a database related to external data is stored. A database related to external data corresponds to Linked Data. In this case, the data user operates the data receiving device 320 to transmit external data and a request for pseudo sample data related to the associated data to the data providing device 310 .

[0200] In this embodiment, by Figure 15A The database re...

Abstract

An information processing apparatus includes a calculation unit and a generation unit. The calculation unit is configured to calculate a frequency function which is a function relating to an appearance frequency of one or more attribute values of a database having a predetermined attribute and the one or more attribute values relating to the attribute. The generation unit is configured to generate sample data in accordance with the appearance frequency relating to the database on the basis of the frequency function calculated, the sample data including at least a part of the one or more attribute values as one or more sample attribute values.

Description

technical field [0001] The present disclosure relates to an information processing device, an information processing method, a program, and an information processing system for providing, for example, a database. Background technique [0002] For example, Japanese Patent Application Laid-Open No. 2010-93424 discloses a technique of obtaining only statistical values ​​as a result of aggregation of data by a statistical method, while hiding individual data in a database. For example, the above-mentioned techniques are used in the case of distributing consumer information etc. held by various organizations (such as companies) for academic research or market analysis. [0003] In the data aggregation method disclosed in Japanese Patent Application Laid-Open No. 2010-93424, a transformation operation by a function capable of defining an inverse function of data is performed, and disturbance processing is performed on the transformed data. Based on the perturbed data obtained by ...
