Improving Cloud Security Using Data Partitioning And Encryption Technique

Abstract- Cloud computing is Internet based computing where virtual shared servers provide software and other resources and hosting to customers on a pay-as-you-use basis. Cloud storage is nothing but the storing data on third party cloud servers. Advantages of cloud computing are almost unlimited storage and backup and recovery. Disadvantages of cloud computing are technical issues, cost and lack of support. But main disadvantage is security. As we store our data on third party cloud service providers our data is not completely safe. It impose a great risk. Many cloud servers are curious servers i.e., they try to read the data which is stored on it. In this paper our goal is to build an application for improving cloud security using partition and encryption method which will help to improve the cloud security. In this first we take file from client and divide it into number of parts. After partition we encrypt the all file parts. Then we send file parts to different cloud servers. When client want that data back we took that data from cloud servers and decrypt that data. After decryption we merge that data and give it to client. Our goal is that the application should have simple user interface for users flexibility
