Data integrity is very important when a clients store their data into the cloud. Clients must be assured that the files which are stored in the cloud are secured. Mean while cloud server storage space should not be occupied by duplicate content.Most of the existing dynamic Poss, a tag used for integrity verification is generated by the secret key of the uploader.Thus, other owners who have the ownership of the file but have not uploaded it due to the cross-user deduplication on the client-side cannot generate a new tag when they update the file. The dynamic Poss would fail when someone is modified the file content, that user’s ownership will be removed from common file and store the altered file in separate space. When someone is removed the file content then whose ownership is detached.
