Recent advancements in technology has brought many changes in safeguarding, computing and storing of data. The questionable factors in the context of data privacy that is computing and sharing enormous sets of data have also augmented. Homomorphic encryption is one such technique which guarantees franchise in safeguarding information under cryptographic domain .Wise use of four familiar arithmetic operators in a diverse way en routes a powerful homomorphic tool. The paper illuminates the usage of this selfsame tool to provide an efficacious strategy in bringing all security concerns of cloud under check and also analyze these secured datum using big data analytics.
