Title:

A database Disturbance parameter deciding device, a method, a program, and a database Disturbance system

Document Type and Number:

Japanese Patent JP5945490

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a technique for determining a parameter used for a database disturbance technique satisfying Pk-anonymity, the technique being applicable even when an attribute value is a numeral.SOLUTION: A database disturbance parameter setting device determines a parameter p satisfying the following expression. The parameter p is used for the database disturbance technique for disturbing a table by, for each of some or all of attribute values included in the table, setting an attribute of each attribute value v as a, a definition region of an attribute v,u before the disturbance as V, and an attribute v',u' after the disturbance, and carrying out the disturbance based upon a probability density function A(p)determined by the predetermined parameter p and setting an attribute v' after the disturbance.
