An information processing system includes a client device and a server device. The client device includes a transmitter that transmits, to the server device, a request to acquire information for connecting to an external device that provides an external service. The server device includes a storage that stores attributes of accounts of the external service, and the information for connecting to the external device by using the accounts; a receiver that receives the acquisition request from the client device; an identifier that identifies candidate accounts to be used when the client device receives the external service, the candidate accounts being identified based on information elements and the attributes, the information elements being included in the acquisition request and identifying the accounts; and a transmitter that transmits, to the client device, the information for connecting to the external device by using the identified candidate accounts.

Information processing system, server device, and method for processing information

An information processing system including at least one information processing apparatus includes an access control unit configured to receive a request from a service use apparatus to a service providing apparatus, to give, in a case where the request includes information of a completed authentication, based on setup information in which a type of giving information to be given to the request is set, the giving information of the type set in the setup information, and to send the request to the service providing apparatus; and an information providing unit configured to administer the giving information corresponding to the information of the completed authentication, and to provide the giving information corresponding to the information of the completed authentication received from the access control unit to the access control unit.

Information processing system, information processing apparatus, access control method, and program

An information processing system includes a service utilizing device and at least one information processing device to provide a service for the service utilizing device. A temporary code issuing unit to issue a temporary code is provided in the information processing device. A device authentication token generation unit is provided in the service utilizing device and generates a device authentication token by using the temporary code obtained from the information processing device. A device authentication ticket issuing unit is provided in the information processing device and verifies whether the device authentication token obtained from the service utilizing device is valid by using the temporary code and issues a device authentication ticket depending on a verification result. An access unit is provided in the service utilizing device and accesses a resource in the information processing device by using the device authentication ticket obtained from the information processing device.

Information processing system and authentication method

A data processing system including a data processing apparatus, includes a user data storing unit that stores user data of a user who uses a first service, the user data including first authentication data used for logging in the first service and user specifying data; a determining unit that determines, when the user who uses the first service sets second authentication data used for logging in a second service different from the first service, user specifying data usable as the second authentication data from the user specifying data included in the user data; and a management unit that sets the user specifying data determined to be usable as the second authentication data in the user data of the user who uses the first service as the second authentication data, and manages the user data as user data of the user who uses the first service and the second service.

Data processing system, data processing apparatus and log in method

An information processing system includes an information processing device, and an electronic device to utilize a service provided from the information processing device. A service delivery unit provides the service for the electronic device. An information management unit manages license information of the service, generates use permission information and sends the generated use permission information to the electronic device. An execution management unit manages an execution request of the service specifying the use permission information of the service. An execution unit determines whether to have a use authority of a function of the electronic device utilized by the service based on contents of the license included in the use permission information of the service and executes the service by utilizing the function of the electronic device upon determining that the use authority of the function of the electronic device utilized by the service is present.
