This work presents a practical multi-layered encryption and privacy-preserving framework designed to enhance data confidentiality in cloud storage environments. The proposed approach integrates symmetric encryption for data protection, hybrid cryptographic techniques for secure key management, and attribute-based encryption to enforce fine-grained access control. By combining multiple protection layers, the framework mitigates common cloud threats such as unauthorized access, insider attacks, and data leakage. A detailed security analysis is provided to demonstrate how each layer contributes to improved confidentiality, along with a performance evaluation that highlights the feasibility of deploying the framework in real-world cloud systems. The proposed solution emphasizes practical applicability and scalability rather than the design of new cryptographic primitives.
