In order to defend data protection and confidentiality for each tenant, cloud service providers (CSPs) apply multi-tenant schemes to their shared services. Mostly, a tenant, in its existence, owns a share of on-demand cloud resources such as users, virtual machine (VM) instances and storage containers. With the service-oriented architecture (SOA), all the services in a cloud need to support multi-tenancy and conform to a consolidated authorization model. We decision such models as multi-tenant access management models that area unit compatible with the options of the cloud, namely, centralized facility, agility, homogeneity and out-sourcing trust. Multi-tenant access management models ought to be ready to address each intra-tenant and cross-tenant accesses. The previous provides authorization schemes for single-tenant situations. The latter allows collaboration among tenants, which is raising trend of cloud evolution. Key words: Multi-Tenant, Revoke, Access control, R-RBAC, RW-Access, TSP.

INTRODCUTION In cloud computing environment Database as a service (DaaS) offers to business organizations without investing and local maintenance they can outsource their data to the cloud. Now who is tenant, a tenant is a group of cloud users who share and collaborate common resources in cloud storage. In cloud computing tenants are single tenant and multitenant, if a storage server dedicated to single user called single tenant, whereas same
