Safe framework fully embodying grading and decentralization of authority

The invention relates to a safe framework fully embodying grading and decentralization of authority, comprising the following parts: data authorization: defining different roles in a configuration file, and providing different authorities for the roles for data inquiry; data verification: before data obtaining, firstly obtaining the data authorities, then obtaining the data, and then filtering off the data which is not permitted for inquiry according to the data authorities; function authorization: defining different roles in the configuration file, and providing different authorities for theroles for function scheduling; and function verification: before scheduling a method, firstly obtaining the data authorities, then scheduling the method, and then filtering off the methods which are not permitted for access according to the authorities. The invention has the integral advantages as below: the safe framework fully embodying grading and decentralization of authority is simple for use and does not need seasonal compiling of any code related to safety in an application code for achieving the aim of protecting application systems. The safe framework of grading and decentralization of authority embodies the low coupling between the application systems and the safety.
