Kind Code:
A1
Abstract:
The present invention provides an anonymization device capable of correctly assesses whether or not disclosure of privacy information subjected to a statistical (analysis) process is permissible. The anonymization device is provided with: an entropy calculation means which calculates the entropy of a function for which parameters are determined, as a result of curve fitting to attribute information of a plurality of individuals; and an anonymity calculation means which calculates non-fitting degree of the function to which the parameters are determined, relative to the attribute information, and calculates and outputs anonymity of the function to which the parameters are determined, on the basis of the non-fitting degree and the entropy.
