When storage of the data in necessary over cloud data integrity verification is one of the biggest security issue. Provable data possession is one of the method available for checking the integrity of data. In this paper, the authors have concentrated on the creation of an efficient PDP method for distributed cloud storage, in which they consider the existence of multiple cloud service providers maintaining and storing client's data in cooperative manner. This cooperatively working PDP method is based on indexing hierarchy & homomorphic variable response method.
