The dawn of the cloud computing makes storage outsourcing become a rising trend, which promotes the secure data auditing a hot topic that appeared in the research literature. In recent times some research reflect on the problem of secure and efficient public data integrity auditing for secure active data. However previous schemes were not efficient for securing and sharing data among user and maintain the concept of Revocation. In this paper, we figure out the collusion attack in the exiting scheme and provide an efficient secure data auditing scheme with secure group user revocation based on SHA1 and user key generation algorithm revocation group signature. We design a tangible design based on the our scheme definition. Our schema supports the tight security for data and efficient Revocation with some very nice properties like secure sharing of data, choosing a particular group to make data secure, allowing member to upload data, confidentiality and traceability. Finally, the security and experimental exploration show that, compared with its relevant schemes our scheme is also secure and efficient.
