Abstract
A method executed by a hardware processor of a computer to manage use of a service at a terminal device, includes: receiving, from the terminal device via a communication network, identification information and authentication information that are input by a user to the terminal device to log in to the service; and in a case that a login to the service is not permitted based on the identification information and the authentication information, permitting a temporary login in which a restriction is placed on some functions of the service.
Claims14
A method executed by a hardware processor of a computer to manage use of an educational service at a terminal device, the method comprising:
- receiving, from the terminal device via a communication network, an output signal including identification information and authentication information that are input by a user to the terminal device to log in to the educational service;
- determining whether a login to the educational service is permitted based on the identification information and the authentication information;
- and
- in a case where the login to the educational service is not permitted, permitting a temporary login in which a restriction is placed on some functions of the educational service, wherein
- the determining whether the login to the educational service is permitted includes:
- based on a global IP address contained in the output signal received from the terminal device, identifying a class to which the user belongs, and
- upon determining that the global IP address matches with a global IP address of another terminal device of another user who belongs to the identified class and normally logs in, determining that the user is capable of logging in, and
- the restriction includes at least one of:
- limiting a time during which the user can join a class provided by the educational service, and
- prohibiting viewing another user's screen during the class.
A method executed by a hardware processor of a computer to manage use of an educational service at a terminal device, the method comprising:
- receiving, from the terminal device via a communication network, an output signal including identification information and authentication information that are input by a user to the terminal device to log in to the educational service;
- determining whether the user is valid based on the output signal in response to input authentication information that is not registered in association with the identification information;
- and
- permitting, based on a determination that the user is valid, a temporary login in which a restriction is placed on some functions of the educational service, wherein
- the determining whether the user is valid includes:
- based on a global IP address contained in the output signal received from the terminal device, identify a class to which the user belongs, and
- upon determining that the global IP address matches with a global IP address of another terminal device of another user who belongs to the identified class and normally logs in, the determining that the user is valid, and
- the restriction includes at least one of:
- limiting a time during which the user can join a class provided by the educational service, and
- prohibiting viewing another user's screen during the class.
