Privacy Preserving Ranked Keyword Search over Encrypted Cloud Data
We present a scheme that discusses secure rank based keyword search over an encrypted cloud data. The data that has to be outsourced is encrypted using symmetric encryption algorithm for data confidentiality. The index file of the keyword set that has to be searched is outsourced to the local trusted server where the keyword set that is generated from the data files is also stored. This is done...
متن کاملPrivacy- Preserving Keyword-based Semantic Search over Encrypted Cloud Data
To protect the privacy, sensitive information has to be encrypted before outsourcing to the cloud. Thus the effective data utilization becomes a significant challenge. Searchable encryption scheme has been developed to conduct retrieval over encrypted data. However, these schemes only support exact keyword search. Recent fuzzy search schemes mainly evaluate the similarity of keywords from the s...
متن کاملPrivacy Preserving Keyword Search over Encrypted Cloud Data
Cloud computing enables the organizations to outsource their data by providing a service model called infrastructure as a service (IaaS). In a public cloud the infrastructure is owned and managed by a cloud service provider and is located in the provider’s control. To protect the privacy of sensitive data, documents have to be encrypted before outsourcing. When the number of encrypted documents...
متن کاملPrivacy-Preserving Keyword Search Over Encrypted Data in Cloud Computing
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 domains – information retrieval for index representation, algorithms ...
متن کاملAn Efficient and Privacy-Preserving Semantic Multi-Keyword Ranked Search over Encrypted Cloud Data
As so much advantage of cloud computing, more and more data owners centralize their sensitive data into the cloud. With a mass of data files stored in the cloud server, it is important to provide keyword based search service to data user. However, in order to protect the data privacy, sensitive data is usually encrypted before outsourced to the cloud server, which makes the search technologies ...
