Abstract—
This paper introduced a robust and efficient framework designed to ensure secure dynamic data handling and public auditing in cloud storage systems. The primary goal was to strengthen data integrity and user confidentiality using advanced cryptographic methods and privacy-aware third-party auditing (TPA). An in- depth analysis of existing cloud security models was conducted to uncover persistent challenges such as secure management of data updates, protection of user privacy, and reliable auditing within potentially untrusted cloud environments.
To address these issues, a modular system architecture was developed that supports dynamic data operations—including insertion, deletion, and modification—while enabling secure data outsourcing. The auditing mechanism allows a trusted third party to verify data integrity without exposing sensitive information, ensuring both transparency and privacy. Additionally, the framework incorporates lightweight cryptographic algorithms aimed at reducing computational and communication costs.A comprehensive feasibility study was performed, and the necessary hardware and software requirements were identified to support real-world implementation. The proposed solution demonstrated high potential for scalability, efficiency, and user trust. Overall, the framework offers a practical pathway toward secure, transparent, and user-centric cloud data management, making it a valuable contribution to advancing cloud storage security.
