Security and authentication to the data stored in the cloud is the major challenge. The paper presents major three aspects. First, it not only provides the binary status about the storage information but provides integration of the storage correctness information and data error localization (i.e. locates the misbehaving servers). Second, it supports data integrity to the dynamic operations such as update, delete and append. Third, the system is highly efficient and resilient against failures, data modifications, and even server colluding attacks.
