Now a day even though Cloud services offer flexibility, scalability, there have been proportionate concerns about security. As more data moves from centrally located server storage to the cloud storage. Security is the most important factor related to the cloud computing. As the users can stores his private data on cloud with the help of cloud service providers. Data stored on single cloud is risk of service availability failure due to attacker enters in single cloud.
Our approach is to movement towards multi-clouds that is data stored on multi-cloud service providers. In this system we propose a secured cost-effective multi-cloud storage (SCMCS) model in cloud computing in which holds an economical distribution of data among the available cloud service provider (SP) in the market, instead of single cloud to provide customers with data availability as well as security. This work aims to encourage the use of multi-clouds due to its ability to reduce security risks that affect the cloud computing user. Our proposed model provides a better security for customer’s data according to their available budgets from that they can choose cloud service provider.

Cloud computing is nothing but rate server and internet based model .A huge amount of data being retrieved from geographically distributed data sources and non localized data handling requirements. The industrial information technology towards a subscription based or pay-per-use service business model known as cloud computing. One of the advantage of cloud computing is cloud data storage, in which users do not have to store his own data on their own servers , where instead their data will be stored on the cloud service provider’s servers. For that reason users have to pay the service charge to service provider for this storage service. This service does not provide only flexibility and scalability for the data storage it also provides customers with the benefit of paying a charge only amount of data they need to store for particular time.
To access this cloud services security and reliability we are using different modules like: 1) Using single cloud service provider. 2) Using multiple cloud service providers. The drawback of single cloud service provider is that it can be easily hacked by any attacker. In multiple cloud service provider model gives better security and availability of user private data.

Data integrity and privacy of the data are the most critical issues in cloud storage. For that reason cloud service provider have standard techniques and hybrid model . In this work we provide better privacy and availability of user’s data can be achieved by dividing into block of data pieces and distributing them among the cloud service provider’s in such way that for retrieving original...
