This research presents a stub signature–based system designed to improve the security and efficiency of public data auditing in cloud environments. By using lightweight, dynamically generated signatures, the framework enables third-party auditors to verify data integrity without accessing or exposing the original data. The approach reduces computation overhead, enhances privacy preservation, and ensures transparent and reliable auditing. This model strengthens trust between users and cloud providers while supporting scalable and secure cloud storage operations.
