In Cloud Computing,a basic application is to source the knowledge to outside cloud servers for climbable knowledge storage. The outsourced knowledge,however,have to be compelled to be encrypted because of the privacy and secrecy issues of their owner. This leads to the well-known difficulties on the accurate search over the encrypted cloud knowledge. To tackle this issue,during this paper,we have a tendency to develop the searchable coding for multikeyword hierarchal search above the storage knowledge. The main aim of this paper is to preserve the outsourced data in cloud through gateway encryption and blind storage,and to implement multi keyword ranked search over the encrypts data in a safe way by NLP method without has download and decrypts the entire group of member file contents. © 2016,International Journal of Pharmacy and Technology.
