Mobile terminal safety middleware system and method based on metadata

The invention discloses a mobile terminal safety middleware system based on metadata, relating to the technical field of communication. The system comprises a role layer, a security resource management layer and a basic resource layer and adopts a metadata drive form to manage, and thus the coupling property between modules is reduced; the role layer is used for providing two roles, namely users and developers; the security resource management layer consists of an application program programmatic interface, a message engine, a service control center, a service information center and a development tool module; and the basic resource layer is used for providing an application service operation environment and a security service specific implementation and comprises a resource providing layer and a resource interface layer module. The terminal user can order the security service or issue the security service demand according to the requirement; and the developer calls existing service or the developed novel security service and deploys the existing service or the developed novel security service to a platform. The security service development process of the terminal has favorable expansibility, high efficiency and sharing property.
