| Abstract(in English) | Universities and companies access personal information databases for a wide range of purposes, and privacy considerations must be taken into account when using such databases. Most of the existing anonymization technologies excludes identifiers that uniquely identify individuals and process quasi-identifiers (QIDs), which do not uniquely identify an individual but are well-correlated with that individual. Here we propose an anonymization algorithm based on a non-processing method for QIDs called the dummy record %addition method, and this algorithm succussed reduces the number of dummy records added for anonymization. A verification experiment confirmed a more balanced safety-usefulness tradeoff in the proposed algorithm than in %comparative existing technologies while maintaining the $l$-diversity, a main indicator of privacy security. |
