METHOD AND SYSTEM OF DUAL AUTHENTICATION SERVICE FOR MEASURING OBSTACLE USING DYNAMIC QUERY SWITCH OF HETEROGENEOUS DB

摘要

PURPOSE: A method and a system of a dual authentication service for measuring obstacle using a dynamic query switch of heterogeneous are provided to supply a mobile communication service without interruption by converting a process configuration dynamically. CONSTITUTION: In a device, first certificate servers(110,120) update and stores basic data, and it performs authentication based on updated basic data. Second certificate servers(130,140) backup basic data. The second certificate server is operated by a switch signal and performs authentication based on basic data in case that the first certificate server has a trouble. The first certificate server and the second certificate server use a pair of SQL query to be connected to heterogeneous databases respectively. The first certificate server performs authentication by using one of SQL queries while the second certificate server performs authentication by using the other of SQL queries according to a switch signal.
