This is in contrast to cryptographic hash functions and checksums, which are designed to have maximum output difference between adjacent inputs. Locality preserving hashes are related to space-filling curves and locality sensitive hashing. ==External links== * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Locality preserving hashing」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
