The Institute of Electronics, Information and Communication Engineers, IEICE technical report. Life intelligence and office information systems, 114, 32, 11, 18, 20140515, Anonymization of personal data is expected to be one of the solution to use personal data in a secure manner. However, there is a trade-off between the safety and the usability of anonymized data, and it is known that when the data is processed to be highly safe, the usability of anonymized data decreases siginificantly using conventional anonymization techniques. As approach to solve this problem, we implemented probabilistic k-anonymity in our personal data anonymization system, and made an evaluation using published data and synthetic data. From the evaluation result, we found that the usability of anonymized data differ each even if the parameter given to the system is the same, and it depends on the distribution of the vale in data. In this report, we consider the condition to achieve high usability using probabilistic k-anonymization.
