Verification of Ranked Keyword Search in Cloud Computing

In the recent era of cloud computing, Many people move towards the outsource their information to the cloud. As a fundamental data use, secure search over encrypted cloud data has attracted the interest of many researchers recently. This is the reason researchers assume that the cloud server is curious and honest, where the search results are not confirmed. In this paper we describe that if cloud server misbehave and working dishonestly then catch them. Base on this model, we investigate the issue of result verification for the secure ranked search. Not the same as past information verification schemes, we propose a novel obstacle based scheme. With our carefully devised verification data, the cloud server can't know which data owner, or what number of data owner exchange anchor data which will be utilized for verifying the cloud server's misbehavior. With our methodically designed verification construction, the cloud server can't know which Data Owner data are embedded in the verification data buffer, or what no of Data Owner's verification data are really utilized for verification. All cloud server knows that, if he acts dishonestly at number of times then he must be punished. we propose to optimize the estimation of parameters utilized as a part of the development of the secret verification data buffer At last, with careful investigation and extensive experiments, we confirm the accuracy and efficiency of our proposed schemes.
