An Efficient Search in Cloud Computing Using Ranked Keyword Search Algorithm

R. Aravind

Abstract: Cloud computing is a subscription-based service where the networked storage space and computer resources can be obtained. Cloud computing economically enables the paradigm of data service outsourcing. However; to protect data privacy; sensitive cloud data have to be encrypted before outsourced to the commercial public cloud; which makes effective data utilization. In the proposed system; the problem of effective secure ranked keyword search over encrypted cloud data is done. Ranked keyword search greatly enhances the system usability by returning the matching files in a ranked order. The files are matched according to certain criteria and it makes one step closer towards the deployment of privacy-preserving data hosting services in Cloud Computing. The resulting design is able to facilitate efficient server-side ranking without losing keyword privacy. In the proposed system; the querying process over the cloud computing infrastructure (IAAS) using secured and encrypted data access and ranking is performed for the getting better results.
