Differential privacy is a promising paradigms to achieve proven privacy, but previous methods to assure the differential privacy have several drawbacks on data utility and scalability in practice, in particular when applied to publishing large and sparse tabular data such as geospatial data. This paper proposes a novel differentially private method that simultaneously solves these problems, and demonstrates its evaluation results. The proposed method introduces a process to correct for the non-negative restriction of the output data by modifying the wavelet coefficients of the perturbed data, and this correction process enables the proposed method to efficiently process large sparse data in terms of scalability and accuracy. In addition, the proposed method effectively suppresses the amount of noise required to process multi-dimensional data by reducing its dimensionality using a locality-preserving mapping method called Morton order mapping.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1816","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1801","bibliographicIssueDates":{"bibliographicIssueDate":"2015-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"56"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:20:45.074381+00:00","id":145065,"links":{}}
