WebJan 22, 2024 · Efficient and Expressive Keyword Search Over Encrypted Data in Cloud Consider a cloud-based healthcare information system that hosts outsourced personal health records (PHRs) from different healthcare providers. To comply with privacy regulations like HIPAA, the PHRs are encrypted. WebJan 1, 2013 · Abstract. Search over encrypted data is a technique of great interest in the cloud computing era, because many believe that sensitive data has to be encrypted before outsourcing to the cloud servers in order to ensure user data privacy. Devising an efficient and secure search scheme over encrypted data involves techniques from multiple …

Expressive query over outsourced encrypted data
Web1 hour ago · Encryption is tough to implement, and it generally requires all correspondents to participate. The process isn’t end-to-end if your email uses encryption, but mine … WebThere exist several desirable features: (1) Data owners can set search permissions for outsourced encrypted data according to an access control policy. (2) Multiple users, whose attributes satisfy the access control policy, are allowed to perform a retrieval operation upon the encrypted data. WebIn this paper, we design a novel privacy-preserving functional encryption-based search mechanism over encrypted cloud data. A major advantage of our new primitive compared with the existing public key based search systems is that it supports an extreme expressive search mode, regular language search. responsibilities of a cfo in a small business
