This study discusses cloud-based secure group data sharing for dynamic groups. Any cloud user can anonymously exchange data with others by utilizing group signature and dynamic broadcast encryption techniques. To develop a cloud-based solution that addresses both QOS and security concerns. The untrusted cloud will be used to provide a security solution for dynamic group users. We provide customers with a safe and secure access control system that allows everyone participating in a social event to use the cloud resource anonymously. We undertake extensive generations to demonstrate the suitability of our arrangement in terms of the extent limit and estimation overhead .Disseminated figuring is a classic and profitable approach of share social event resources among cloud users. Surprisingly, given the ongoing changing of the enrollment, sharing data in a multi-proprietor manner while shielding data and identity protection from an untrusted cloud is still a testing issue.
