Search Technique on Encrypted Cloud Data for Conceptual Information

Improving Search Efficiency of Encrypted Cloud Data

CLOUD computing is a new technique to provide and consume the services based on the Internet, by providing for virtualized resources as a service. This is provided over the network. To protect the privacy of the sensitive data, the data stored in the cloud have to be encrypted before outsourced to the commercial public cloud. In such case, the effective data utilization service is a very challe...

Privacy-preserving Logarithmic-time Search on Encrypted Data in Cloud

Ideally, a privacy-preserving database-in-the-cloud environment would allow a database owner to outsource its encrypted database to a cloud server. The owner would retain control over what records can be queried and by whom, by granting each authorized user a search token and a decryption key. A user would then present this token to cloud server who would use it to find encrypted matching recor...

A Unified Framework for Secure Search Over Encrypted Cloud Data

This paper presents a unified framework that supports different types of privacy-preserving search queries over encrypted cloud data. In the framework, users can perform any of the multi-keyword search, range search and k-nearest neighbor search operations in a privacypreserving manner. All three types of queries are transformed into predicate-based search leveraging bucketization, locality sen...

Statistics on Encrypted Cloud Data

As an increasing number of data is to be processed, outsourcing data to the cloud environment becomes an appealing proposal to heighten the computation/storage efficiency, while avoiding costly and complicated system construction. However, it is necessary to encrypt the outsourced data to prevent the breaches of both data confidentiality and privacy. Most of the statistical procedures deal with...
