Abstract: An information processing apparatus includes: a receiving unit that receives an issue request for an electronic certificate from an external apparatus; an issuing unit that, when the issue request received by the receiving unit is for issuance of an electronic certificate using a first calculation method for calculating a hash value, issues the electronic certificate using the first calculation method; a transferring unit that, when the issue request received by the receiving unit is for issuance of an electronic certificate using a second calculation method different from the first calculation method, transfers the issue request to another information processing apparatus that issues an electronic certificate using the second calculation method; and a transmitting unit that, when receiving the electronic certificate using the second calculation method from the another information processing apparatus, transmits the received electronic certificate to the external apparatus that has transmitted the issue reque

Abstract: An image forming device that includes a communication device includes a class judging unit, a number-of-times determination unit, and a retry execution unit. The communication device transmits data to a management device through a first communication network provided by a communication carrier. The class judging unit judges a class under which a first error having occurred in data transmission falls, the class being predetermined according to a probability of a successful transmission retry. The number-of-times determination unit determines the number of times a retry is performed in response to the first error, such that the number of times the retry is performed is decreased as the probability of a successful transmission retry becomes low. The retry execution unit causes the communication device to execute the retry in response to the first error the determined number of times.

Abstract: An information processing system includes at least one information processor constituting a group and a management apparatus that manages a help information group. The information processor includes a periodical notifier that periodically notifies the management apparatus of management information, a memory that stores help information provided from the management apparatus, and a presenting unit. If requested help information does not exist in the memory but exists in a second information processor included in the group, the presenting unit acquires the help information from the second information processor and presents it. If the help information does not exist in any information processor within the group, the presenting unit acquires the help information from the management apparatus and presents it.

Abstract: A fax maintenance system includes a fax machine. The fax machine includes an operation fault detector and an output unit. The operation fault detector detects an operation fault of a predetermined type which occurs in the fax machine. The output unit outputs information indicating an occurrence of an operation fault of the predetermined type and setting information concerning an operation fault of the predetermined type.

Abstract: An information processing apparatus includes an acquisition unit and a help controller. The acquisition unit acquires information indicating whether help information is stored in any of information processing apparatuses within the same group as the information processing apparatus. The help controller performs control based on the information acquired by the acquisition unit so as to cause an information processing apparatus within the group to acquire the help information from an external help management apparatus if the help information is not stored in any of the information processing apparatuses within the group or to cause an information processing apparatus within the group to acquire the help information from another information processing apparatus storing the help information in the group if the help information is stored in any of the information processing apparatuses within the group.

Abstract: A management unit communicates with an image forming apparatus via a first communication path and communicates with an information processing apparatus receiving an operation for maintenance for the image forming apparatus, via a second communication path. The management unit includes a memory for storing specifying information for specifying an image forming apparatus, in association with identification information for identifying the image forming apparatus in local communication between the information processing apparatus and the image forming apparatus.

Abstract: A communication apparatus includes a communication unit, a first storage unit, a second storage unit, and a permitting unit. The communication unit communicates with a communication line for which a charge amount is changed in accordance with use of the communication line. The first storage unit stores operation information about an operational condition of the communication apparatus. The second storage unit stores charge information about the charge amount according to the use of the communication line. The permitting unit permits the communication unit to transmit the operation information, on the basis of a result obtained by comparing the charge information with predetermined charge limit information.

Abstract: An authentication agent apparatus includes a communication request reception unit that receives a communication request to a client B of an authentication server from a client A of the authentication server, a data reception unit that receives data to be transmitted to the client B from the client A, an authentication request unit that issues to the authentication server an authentication request on the client A, a communication enabling request unit that requests the authentication server to enable communication between the client A and the client B, an enabling data acquisition unit that acquires enabling data to enable the communication with the client B from the authentication server, and a generation unit that generates transmission data to be transmitted to the client B on the basis of the enabling data and the data to be transmitted.

Abstract: An electronic apparatus includes an authority information acquisition unit that acquires a user's authority information; a first storage unit that stores current control information currently used to control the apparatus; a second storage unit that stores current configuration information representing a current configuration of the apparatus; an available control information outputting unit that outputs available control information allowed to be acquired; an instruction accepting unit that accepts an instruction to acquire at least one of versions of available control information output by the available control information outputting unit; an information acquisition unit that acquires control information according to the instruction accepted by the instruction accepting unit; and an updating unit that updates the current control information stored in the first storage unit.
