Abstract: In multi-cloud storage, the data owners host their data and access the data from cloud servers. However, this new paradigm of data hosting service also introduces new security challenges such as integrity, availability and confidentiality of data. The prior works on ensuring remote data integrity in multi-cloud storage often lacks the address of confidentiality and availability issues, which are always important aspects of quality of service (QoS). In this paper, we propose an effective and secure data storage protocol in multiple cloud. In our design, we encrypt and encode the data before outsourcing into clouds to ensure confidentiality and availability of data respectively. Then, we consider the third party auditor (TPA) to verify the integrity of the data stored in the multi-cloud and extend verification method to support batch verification for multiple owners. Extensive security, performance analysis and experimental results show that our scheme is efficient and secure in multi-cloud.
