The proposed system integrates Advanced Encryption Standard (AES-256) for high-speed data encryption with Rivest–Shamir–Adleman (RSA-4096) for secure key exchange, ensuring both performance and confidentiality. To enhance data integrity and prevent tampering, a blockchain-based hashing mechanism utilizing SHA-256 is incorporated. Additionally, a role-based access control (RBAC) model combined with anomaly detection techniques is employed to restrict unauthorized access and monitor suspicious activities. The architecture is designed to handle diverse data types, including text, images, and sensor data, while maintaining scalability and reliability. Experimental evaluation demonstrates improved throughput, reduced latency, and enhanced security compared to traditional methods. The proposed framework provides a comprehensive, multi-layered solution for secure data storage and transmission in modern cloud-based systems.
