The existing works on security storage in cloud computing cause overhead, data correctness issue, key escrow problem, single point of failure and so on. This develops Multiple Authority based Data Fragmentation Technique for providing Secure Storage in Cloud Computing. It aims to avoid the key escrow and single point of failure issues of secure storage. In this technique, the Cloud Service Provider (CSP) provides multiple services for a client, the trusted and verification authorities are responsible for jointly creating the master key and system parameters and the Cloud Data Owner (CDO) encrypts the documents using CP-ABE. In order to provide data recoverability, a file is divided into blocks and sectors. Probabilistic algorithm checks the integrity of fragmented file. By simulating, the proposed technique reduces the overhead and data failures.
