Privacy Enhancing using HLA scheme while data auditing in cloud

Cloud users can remotely store their data and access the ondemand quality applications and services from a shared pool of computing resources. Cloud computing provides an economical and efficient solution for sharing group resource among cloud users. It is one of the common places for data storage and shared across multiple users. With our proposed mechanism the identity of the signer is kept private from third party auditor who is still able to publicly verify the integrity of shared data without retrieving the entire file while preserving data and identity by using HLA scheme in the cloud
