| Abstract: | A comprehensive method was explored to handle data privacy,availability and integrity challenges in cloud computing.The existing data security techniques were stated,and their solo-function drawback was analyzed and improved.As a consequence,a new idea was proposed to tackle both data privacy and integrity issues by the third party auditor.The proposal not only can verify users' data integrity by batch,but also can construct a credible chain between each party and protect the tenants' data confidentiality. |

| Keywords: | cloud computing data security third party auditor privacy hierarchical protection |
