  • LICENSE NUMBER MANAGEMENT SYSTEM AND LICENSE NUMBER MANAGEMENT METHOD
    Publication number: 20170011482
    Abstract: A license number management system performs a login process according to first authentication or second authentication. The first authentication is performed for allowing usage of a service in both an online and offline status, and the second authentication is performed for allowing usage of the service only in the online status. In a case of authenticating a terminal according to the first authentication, license management information is updated to a used state when data needed for using the service is transmitted to the terminal, and the license management information is updated to a not used state when the data is received from the terminal. In a case of authenticating the terminal according to the second authentication, the license management information is updated to a used state when the terminal is successfully authenticated and the license management information is updated to a not used state when the terminal logs out.
