Utpaul Sarkar presented on building an efficient security model for cloud data storage. The presentation outlined the objective to provide accurate and secure storage while maintaining smooth operations. It reviewed literature on cloud computing models and applications. The research problem is securing data from internal and external attacks in storage that supports dynamic data lightly and securely. The research plan involves studying existing key generation, signature generation, proof generation and verification modules to propose solutions. Constraints include difficulty accessing private data, slow speeds due to low bandwidth, and insufficient required infrastructure.
