Secure semantic based search over cloud
Author(s): Sarulatha.M, Anantha Prabha.P
Abstract: Data are outsourced to the cloud for ease of access. Data is encrypted before outsourcing to the cloud to guarantee the security. To achieve efficient data utilization, searching over encrypted cloud data has a great challenge. In the existing system, MKQE(Multi-keyword query scheme) retrieves only keyword related files MKQE entirely depends on the submitted query keyword and didnâ€™t consider the semantics of keyword..Searching efficiency is improved by semantic based search. Semantic based search is an important and necessary functionality for information retrieval in cloud storage services. This scheme returns the exactly matched files and also semantically related files. Meta data file is created for each file. Cloud server builds the index and dictionary to a keyword. With less communication user can retrieve more files from the cloud server. Files are returned on the basis of the relevance score.
