An Efficient Search in Cloud Computing Using Ranked Keyword Search Algorithm

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.
