Abstract
A server 1 and client 2 have system clock synchronous means 9, 14 for synchronizing a system clocks 6, 12 to the Internet Standard Time, storing means 4, 11 for arranging and storing a plurality of log-in IDs for authenticating said server 1 and client 2 mutually, and log-in ID changing means 8, 13 for searching repeatedly from the top to the bottom of a plurality of log-in IDs stored in said storing means 4, 11, and updating a log-in ID searched at predetermined intervals as the most current log-in ID every time searching.
Claims5
A network system for connecting a client to a server via the Internet, wherein when a log-in ID transmitted by said client matches a log-in ID stored in said server, said client receives permission to log in to said server;
- wherein said server and client each have:
- a system clock;
- system clock synchronous means for synchronizing the system clock to the Internet Standard Time;
- storing means for arranging and storing a plurality of log-in IDs for mutually authenticating said server and client;
- and
- log-in ID changing means for searching at predetermined intervals from the top to the bottom of the plurality of log-in IDs stored in said storing means, and for every search updating a log-in ID as the most current log-in ID, wherein the log-in ID changing means of the server and the client are synchronized by the respective system clock synchronous means.
Plug-in software for an Internet browser operating a computer as communication means transmitting and receiving electronic data via the Internet;
- wherein said computer is operated as:
- system clock synchronous means for getting the Internet Standard Time from the Internet and for synchronizing a system clock of said computer to the Internet Standard Time;
- storing means for arranging and storing a plurality of log-in IDs received from a server;
- log-in ID changing means for searching on the basis of the Internet Standard Time at predetermined intervals from the top to the bottom of the plurality of log-in IDs stored in said storing means, and for every search updating a log-in ID as the most current log-in ID;
- and
- transmit/receive means for transmitting the most current log-in ID to said server and logging in to said server.
