Attribute-based access control scheme ensures that users have legitimate attribute to access the shared data.With attributes unauthorized, users can't access the data.But if we want a finer control to the data, some users, having attributes satisfied the access control structures within a certain number, can access the data and the others can't.A simple attribute-based access control method can't meet the above requirements.In this paper, based on the access control needs, we have designed an access control scheme, which can limit the number of users, who can access the shared data.It can limit the number of users effectively and data were shared security at the same time.
