Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to the security information interaction system, terminal, server and method, and more particularly, to the security information interaction system, terminal, server and method based on the thin terminal mode. 
       BACKGROUND 
       [0002]    Nowadays, with the increasingly widespread of the network applications and increasingly enrichment of business types of different fields, it becomes more and more important to perform the interaction of the security information (i.e., the information requiring a higher level of security) by means of a security information interaction terminal (especially, a mobile terminal). 
         [0003]    In the existing security information interaction systems and methods, the C/S (client/server) mode is usually adopted, that is, each application service provider has the server for implementing said application service, and the security information interaction terminal (such as the mobile terminal) corresponding to each server has a client corresponding to that server, i.e., if a certain security information interaction terminal needs to use the application service provided by a certain server, then it must be installed with a specific client corresponding to that server and directly communicate with the server through the client so as to complete the security information interaction procedure, in other words, different servers have corresponding clients different from each other. 
         [0004]    However, the existing security information interaction systems and methods have the following problems: (1) due to the fact that the client must bind with a specific server, the security information interaction terminal having a single client would not use application services provided by a plurality of different application service providers, in addition, if a plurality of clients are installed in the security information interaction terminal, it may lead to a conflict or the difficult compatibility between each other, thereby reducing the expansibility and compatibility of the security information interaction system and method; (2) since different clients corresponding to the same server need to be installed for different types of security information interaction terminals, the existing security information interaction systems and methods have lower terminal compatibility; (3) when the application running in said server needs to be expanded and upgraded, the client corresponding that server needs to be upgraded as well, resulting in the network (especially, the mobile network) load increase, and then decreasing the work efficiency and performance of the security information interaction system and method. 
         [0005]    Therefore, there exist the needs for providing a security information interaction system, terminal, server and method, which can compatibly use multiple servers providing different application services, and have higher work efficiency and performance.
