This paper presents a database security model named DSP-MAC,which is based on the study in the special needs of the database security proxy for access control.The model adopt the smallest particle size of the object as attributes-level and tuple-level,the subject and object have been defined and Classified.It shows the sensibility of the information by define the Security Level about every data,and at the same time,it shows the kinds of data which can be access by define security level for users.Attached to the integrity of the rules,the integrity of physical integrity rules and inference rules have been used in this model.It improve the level of the security significantly.
