Storing data in the cloud is a new multi-tenant database solution that has recently emerged to deliver database for multiple users, who can store and access their data over the internet. This multi-tenant database designed to be used by multiple tenants and each tenant may have multiple users. Therefore, this database type demands a special multi-tenant access control model, which provides an access control not only for multiple tenants, but also for multiple users per tenant. In this paper, we are proposing a multi-tenant access control model based on a multi-tenant database schema called Elastic Extension Tables (EET). In this model, we define access control data architecture, and the EET access grants which can be granted to tenants' users. Moreover, we propose an access control algorithm, which allows users to access the data granted to them based on a number of groups or roles assigned to these users. © 2013 IEEE.
