ABSTRACT
Cloud Computing is a technology that allows the users to store their data at a remote place without the need of physical possession. There are a number of cloud service providers (CSPs) available to provide storage services. But, the problems that need to be addressed in a cloud environment are the security and integrity of the data. Ultimately, it is the task of the CSPs to ensure that the data has not been modified and free from security risks. Also the data may be lost because of a server failure. In order to address these problems, a security scheme is proposed that integrates both erasure code and raptor code. The data integrity is ensured using the token values based on erasure and raptor codes. The same codes are used to recover the original data from the cloud server in case of a server failure, as these schemes help to distribute files across several servers.
