Abstract

The Cloud Computing, becomes sensitive information are being increasingly centralized into the cloud. In support of the protection of data privacy, responsive data has to be encrypted previous to outsourcing, which makes effective data consumption a very difficult task. Although traditional searchable encryption schemes allow users to securely search over encrypted data throughout keywords, these technique support only Boolean search, without capturing any relevance of data files. This come up to suffers from two main drawbacks, Not using centralized data sharing mechanism, Also the perturbed data do not produce very accurate data mining results, who do not necessarily have pre-knowledge of the encrypted cloud data, to post process every retrieved file in order to find ones most matching their interest; On the other hand over, invariably recover all files contain the query keyword additional incur pointless network traffic, we propose to further extend the scheme is big data classification technique to consider the extensibility of the file locate and the multi-user cloud environments. On the way to this direction.Various initial results on the extensibility and the multiuser cloud environments. An extra interesting topic is to enlarge the very much scalable searchable encryption to enable capable search on huge practical databases. Here explore a AES based encryption technique where access key generation for user is based on access policies assigned to each user along with the attributes. The data stored in the cloud is encrypted using a key generated based on the access permissions assigned to the data and attributes of the owners who share their data with high security and integrity using policy based encryption technique
