- <h2>Abstract</h2> <div>In recent years, the rapid growth of digital storage has increased the demand for reliable and practical file protection mechanisms. Individuals and organizations frequently store sensitive information such as personal documents, images, academic records, and confidential files on local systems, where they remain vulnerable to unauthorized access, accidental modification, and data misuse. Although several security solutions are available, many require advanced technical expertise or depend heavily on cloud-based services, which may introduce additional privacy concerns. To address these challenges, this paper proposes a Lightweight Privacy-Preserving File Protection Framework for Secure Data Storage. The proposed system is designed to provide a simple, efficient, and locally operated security solution that ensures data confidentiality without adding unnecessary system complexity. The framework integrates user authentication and password-based symmetric encryption to securely encrypt and decrypt files and images. All operations are executed within the local environment, eliminating reliance on third-party servers and enhancing user privacy. Furthermore, the system maintains a local encryption activity log to record file protection operations, thereby improving transparency and user awareness. The overall framework achieves a balanced integration of confidentiality, controlled access, usability, and computational efficiency. The proposed solution offers a practical and user-friendly approach to secure local file storage and establishes a foundation for future enhancements such as advanced access control and secure file-sharing capabilities.</div> <h2><span></span>Keywords</h2> File Encryption, Data Confidentiality, User Authentication, Cryptographic Security, Secure Storage Framework, Privacy-Preserving System.
