Abstract
Cloud servers have become an option for the organizations to store their files and data. Security in the hybrid and multi-cloud environment is always a challenge to be considered. Client can access the cloud servers to upload the files and documents. In a particular time, when cloud servers restrict access to client for storing the files, then the client can assign its proxy to process the files and upload them. Contrarily, integrity checking is also a significant security issue. It allows customers to verify if their outsourced data is kept intact without the entire data being downloaded. In Hybrid and Multi Cloud environments, a new proxy-oriented multiple file uploading and integrity checking model is proposed to resolve security problems. This concrete safety protocol is built with the aid in the Multi-Cloud Environment.
