A privacy-preserving protocol for verifiable file search on the cloud

Abstract

Because cloud computing is increasingly popular, a great deal of documentation is outsourced to the cloud with decreased leadership costs and easy access. While encryption helps prevent user data confidentiality, it creates a difficult issue with well-functioning yet virtually efficient safe search features over encrypted information. It should always be encrypted before cloud outsourcing to preserve the privacy of personal documents that are stored in the cloud environment. Retrieving the same data on the cloud is also a still, tedious task. To obtain information, there are several methods available in which keyword-enabled data entry is one of the best methods. Most of these methods are restricted to the handling of a single keyword query. In order to improve search effectiveness and speed, a multi-key word-search method can be used to obtain a respective cloud.
