Cloud computing takes the technology, services, and applications that are similar to those on the Internet and turns them into a self-service utility. It is the delivery of computing as a service rather than a product whereby shared resources, software and information is provided to computers. In these days a single server handles the multiple requests from the user. Here the server has to process the both the request from the user simultaneously, so the processing time will the high. This may leads to loss of data and packets may be delayed and corrupted and also the Data Management and the Services are not Trust Worthy. Users start worrying about losing control of their own data. Also the data processed on clouds are often outsourced, leading to a number of issues related to accountability, including the handling of personally identifiable information. An efficient data placement algorithm is proposed and implemented in this paper. The data placement algorithm will tell us how to place the files efficiently to the containers in object storage. Besides, the files will merge when client needs it back. So some additional algorithms are also used for partitioning and merging of files. So the objective is to achieve good security for cloud storage system, through proposed algorithm by using multiple containers of object storage in cloud. To handle these issues, the paper proposed an approach to store the data through data placement algorithm, to provide authentication and secure access control for data using Crypto-Biometric System (CBS) in cloud computing and to Protect the data from unauthorized access.
