ABSTRACT:
System and method for managing user logins to a restricted computer service over a stateless network. Single user and multiple, or concurrent, user accounts can be maintained with this logging system. Users are assigned a data mask and an internal user ID (IUID). During a login attempt, the mask is used to scan a user login map to determine if the login will be permitted. For single users, the login is allowed if a current session is not already in progress, as indicated by the login map. For concurrent users, the login is allowed if the maximum number of concurrent users for the account does not already exist, as indicated by the login map. When a login is not allowed, a current session may be terminated or set to be terminated after a fixed interval of time, thereby allowing the requested login. A state lookup table (SLT) is maintained to temporarily keep track of each session in progress and includes a session identifier, the IUID, the starting time, and any termination time established for the session.
