It uses the Fuzzy Commitment on integer lattice for the error correction of ambiguous biometric information. The principle of error correction of Fuzzy Commitment is rounding to integer lattice in L∞ space. However, in the case of face recognition, the feature value is encoded to a vector in the Euclidean space, and therefore application of Fuzzy Commitment is difficult. In this paper, we propose a method to realize the Fuzzy Commitment and Fuzzy Signature which is approximately based on the Euclidean distance by using the closest vector search on triangular lattice.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-07-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"45","bibliographicVolumeNumber":"2013-CSEC-62"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:41:46.064150+00:00","id":94460,"links":{}}
