Outsourcing Similarity Search: Encrypted M-Index
Abstract:
Práce analyzuje problém použití podobnostního hledání v cloud prostředí se zaměřením na bezpečnost. Byla navržena obecná metoda, kerá zajišťuje bezpečnost dat nahraných do prostředí cloudu. Tato metoda může být aplikována na libovolnou existující indexovací techniku, která využívá fixní množinu pivotů. Byl implementován prototyp za použití indexovací struktury M-Index. Encrypted M-Index byl testován …moreAbstract:
We propose a similarity index that ensures data privacy and thus is suitable for search systems outsourced in a cloud. The proposed solution can exploit existing efficient metric indexes based on a fixed set of reference points. The method has been fully implemented as a security extension of an existing established approach called M-Index. This Encrypted M-Index supports evaluation of standard range …more
