Abstract

The Japanese Act on the Protection of Personal Information (Act No. 57 of 2003) allows companies to deidentify personal data and to provide them to any third party without obtaining the data subject’s consent. Officially, the “Anonymously Processed Information” will eventually improve public convenience and aid big-data business. In this paper, we aim to clarify the landscape of anonymously processed information databases in Japan. Focusing on disclosed statements that specify the production and provisioning processes for anonymously processed information, we have developed an automated Web crawler system that detects such statements using heuristics associated with legal statements. We demonstrate that our crawler system performs very well in terms of processing time and detection accuracy. In addition, the resulting statistics may prove useful to others exploring the landscape of Japanese personal-data business structures.
