Abstract: An information processing unit includes a communication circuit configured to communicate with a client terminal device, a memory configured to store a program used for executing given processing, and a processor coupled to the memory, configured to issue, when the given processing includes processing of requesting authentication in accordance with a use request received from the client terminal device related to use of the program, an acquisition request of authentication information used for performing the authentication to the client terminal device, and determine, when the processor acquires an authentication result in accordance with the authentication information, whether or not the given processing that is to be performed by the program is executed, based on the authentication result.

Abstract: There is provided a terminal device which includes: a storage unit configured to store an activation determination condition; and a control unit configured to execute a procedure, including: acquiring first position information for indicating an area where the terminal device is located; authenticating an activation based on the activation determination condition stored in the storage unit and the first position information; and inquiring of an information processing apparatus coupled through a communication network as to whether activation is allowable when an authentication result of the authenticating of activation is an activation forbiddance.

Abstract: A management apparatus includes: a determination unit configured to determine whether or not terminal device identification information that is included in received terminal information is correct based on whether or not communication that uses communication module identification information of a terminal device including storage device identification information, included in the terminal management information, that is identical to storage device identification information included in the received terminal information and that corresponds to a terminal device other than a terminal device specified by terminal device identification information included in the received terminal information is established; and an update unit configured to update the terminal management information according to the received terminal information when the determination unit determines that the terminal device identification information included in the received terminal information is correct.

Abstract: To provide a technology enabling establishment of compatibility between providing convenience for a user inputting authentication information and ensuring high security of a network.
