In this paper we study about the mixture cloud for duplication. Duplications is more important because now a day’s cloud user are facing a big problem based on the storage space. Now a day’s cloud uses are demanding that to increase the storage space because everyone wants to store their data on the cloud. There are many reasons to store data on the cloud because it is safe, if users want to upload data on cloud is more protected. For solving this problem we proposed hash encryption method for finding duplicate data. If user tries to upload data on cloud but he/she doesn’t know about their file is already stored or not, our proposing system can easily find that the file is already stored or not. In this system users data stored in the public cloud. Before these thing users need to tag and key of the file and these two things are provided by the private cloud. Authentication user can do this only; here user should be authorised, private cloud response to user. If user is not valid it does not give any response to the user. In this system user first select the file get tag and convergent from private cloud and upload a file on cloud, if file is already it shows message that the file is already stores or not if not then file will upload successfully on cloud. © 2016, International Journal of Pharmacy and Technology.
