  • Abstract:
  • In cloud storage, data integrity and dedupli cation are critical. Clients must trust that their data is secure while the server avoids storing duplicate files. However, in most existing dynamic Proofs of Storage (POS), integrity tags are tied to the up loader’s secret key. This prevents other rightful owners, who didn't upload due to deduplication, from updating the file. To solve this, when a user modifies or deletes a file, their ownership is detached, and the altered version is stored separately. New owners must prove ownership without uploading the file. Each owner can generate and up load their own authenticated structure, allowing the cloud server to manage multiple structures per file. Upon updates, the server adjusts the related structures to maintain deduplication and integrity.
