RISK ANALYSIS DEVICE, METHOD AND PROGRAM IN ANONYMOUS DATA

摘要

PROBLEM TO BE SOLVED: To provide a risk analysis device for quantitatively analyzing such a risk level that an individual contained in anonymous data is uniquely specified, and optimizing parameters for use in anonymity by using the quantified risk level as a measuring rod, and to provide its method and program.;SOLUTION: A risk analysis device 10 quantitatively analyzes a risk every record constituting anonymous data, quantifies and calculates a risk level of the anonymous data according to a specific scale (e.g., a prior knowledge of an attacker, and a content rate (reproduction rate and F-scale of a conformable rate)) based on the risk analyzed for every record, and outputs the calculated risk level (corresponding to the parameters for use in anonymity).;COPYRIGHT: (C)2016,JPO&INPIT
