Outline of Final Research Achievements

The information protection of an individual is legally defined as unidentifiability. However, this definition is technically vague, and it often leads to the overanonymization of microdata. To mitigate this social loss, we need a clear technical definition of identifiability. Our study aims to clarify this unidentifiability as an object of statistical estimation, and has constructed the detailed theory of this idea. Also our study notes that the exting Anonymized Data have the information of unidentifiability of the data, and thus has measured the possibility of identification on these data of Housing and Land Survey of 2003.
