CloudID: Trustworthy cloud-based and cross-enterprise biometric identification

摘要: In biometric identification systems, the database is typically stored in a trusted server, which also responsible for performing process. However, standalone server may not be able to provide enough storage and processing power large databases. Nowadays, cloud computing solutions have provided users enterprises with various capabilities store process their data third-party centers. maintenance of confidentiality integrity sensitive requires trustworthy proven zero information leakage. this paper, we present CloudID, privacy-preserving cloud-based cross-enterprise solution. It links confidential biometrics stores it an encrypted fashion. Making use searchable encryption technique, performed domain make sure that provider or potential attackers do gain access any even contents individual queries. order create search queries, propose k-d tree structure core encryption. This helps only handling variations domain, but improving overall performance system. Our proposed approach first system disclosure possibility. allows different perform on single without revealing information. experimental results show CloudID performs clients high accuracy minimal overhead disclosure.
