In this paper we talk about the evolvement of cloud computing model and there a structure for secure cloud computing through third party auditing. The giving of the paper is to understand the suggestion of cloud computing and what is meant secure cloud computing via third party auditing rather than suggest a new style and new knowledge to secure cloud computing. Our holistic advance has planned value to those who are using or think using cloud computing because it addresses concerns such as security, privacy and regulations and compliance. In this object, we focus on cloud data storage security, which has always been an important aspect of quality of service. Including: data update, delete and append. Security and performance analysis shows that the proposed scheme is highly efficient and resilient against complex crash, mean data change attack, and even server colluding attacks.
