Construction of Private Methodical Query Services in the Cloud with RASP Data Commotion

Abstract

HOSTING input/data in the cloud is an alluring approach because it provides advantages like scalability and cost-saving. The service owner can increase or decrease the service of cloud infrastructure and pay as per uses. Due to its work the cloud features is very much attractive. It is highly cost and wasteful to serve such forceful workloads with in-house infrastructures. The data owners always desire to submit their quires after realizing the privacy assurance of the cloud. In this aspect researchers have introduced few techniques such as RASP, kNN Algorithm etc. Many a times, data into cloud is stored by maintaining confidentiality, query privacy, efficient query processing at low cost (CPEL Criteria). However, the data owners always desire to submit their quires after realizing the privacy assurance of the cloud. In this aspect researchers have introduced few techniques such as RASP (Random Space Perturbation), k-NN (k-Nearest Neighbour) Algorithm etc. The main problem across RASP technique is, generating the encryption key which is too large and its implementation makes the time and space overhead. Grate information bother technique along with k-NN algorithm is exploited to furnish privacy to the cloud. Wherein, issues such as categorical data and leaked query in the model are identified and addressed, by holding no change in designing the k-NN-R algorithm.
