This project focuses on securing data storage and transmission using end-to-end encryption while implementing a data deduplication mechanism. The core objective is to ensure that identical files are not duplicated within the system, thus optimizing storage space and minimizing unnecessary redundancy. In the event that a user uploads a file with the same name as an existing file, the system will flag it as a duplicate and prevent its storage. The project uses ABE technique encryption, one of the most secure encryption methods available, to protect user data. This encryption ensures that the file content remains inaccessible to unauthorized users, even if intercepted during transmission. Users will be able to search for their files using encrypted identifiers, preventing exposure of sensitive information during the search process. A proxy server facilitates secure communication between the user and the storage system. The server serves as an intermediary, forwarding data requests securely and ensuring the integrity of the information being exchanged. However, malicious users pose a threat to this system, as they may attempt to exploit vulnerabilities to launch attacks, such as data tampering or unauthorized access. The system has been designed with robust security measures to mitigate these risks and protect the integrity of the stored data. By combining data deduplication with advanced encryption techniques and secure data transmission protocols, this project aims to provide a highly secure, efficient, and scalable solution for managing sensitive files while protecting against potential malicious attacks
