Efficient management of files and storage has become crucial in today's world to prevent wastage of cloud storage resources. One commonly used technology for this purpose is data deduplication, which eliminates duplicate copies of files on cloud servers and can significantly reduce storage requirements and save bandwidth. As a result, it can lead to substantial cost savings for cloud service users. Since data security is also a top priority, data is typically stored in encrypted form, and the use of personal encryption keys by data owners can prevent cloud service users from deduplicating their data.
