Abstract: A multifunction apparatus according to the present invention transmits an electromagnetic wave signal to a memory card carried by a user who enters a detection area, scans identification information of the user for user authentication, and starts a warm-up operation immediately after the authentication. Accordingly, the time period spent by the user starting from the user's arrival at the multifunction apparatus until the completion of the warm-up operation is shortened. In addition, the multifunction apparatus determines whether the user remains in the detection area after a job is completed, and transitions from a normal mode to an energy-save mode when it is determined that the user is not remaining in the detection area, the normal mode being in a state where sufficient electrical power is supplied for a job execution, the energy-save mode being in a state where the power supply is decreased compared to the normal mode.

Abstract: An authentication device receives each authentication context including an output information block, an input information block, and an authenticator block. The output information block includes a process result and process result identification information. The input information block includes a process result and process result identification information. The authentication device verifies each authenticator block. The authentication device searches for the output information block having the same value of process result identification information as the value of process result identification information in the input information block from other authentication contexts based on process result identification information in the input information block included in each authentication context.

Abstract: A client apparatus transmits environmental information acquired from an environmental information acquisition device as well as a biometric authentication information matching result to a server apparatus. The server apparatus verifies the validity of the environmental information such as a luminance as well as the validity of the biometric authentication information matching result. If an environment is problematic, the server apparatus notifies the client apparatus that the environmental information is problematic. The client apparatus overcomes the problem of the environment such as the luminance based on the notification from the server apparatus and then retries a biometric authentication. The possibility of re-failure due to the environmental problem can be reduced during a retry of the biometric authentication.

Abstract: A configuration including, in authentication contexts, function unit identification information unique to the function unit that has executed an authentication subprocess in entity devices permits an authentication apparatus to specify the function unit that has executed the authentication subprocess in the entity devices. The verifier, therefore, can verify the legitimacy of the authentication subprocess from the authentication context even in the presence of a plurality of function units capable of executing the same authentication subprocess in the entity devices.

Abstract: Upon receiving server side entity information and a principal confirmation profile request data from a server side entity device, a consolidation apparatus transmits an entity information transmission request to each of a plurality of client side entity devices and receives client side entity information from each of the client side entity devices. Then, it determines the principal confirmation profile ID in each piece of client side entity information and the principal confirmation profile ID in the server side entity information according to the principal confirmation profile ID request information having the highest priority in the principal confirmation profile request data and prepares a routing table information associating the processing capability IDs and the entity IDs corresponding to the determined principal confirmation profile ID, which routing table information is then stored in a memory.

Abstract: Disclosed is a serial-to-parallel converter/parallel-to-serial converter/FIFO unified circuit which includes a register, a selector and a counter. The register receives serial input data and converts the serial data into parallel data based on frequency-divided multi-phase clock signals from a counter. The selector receives the parallel data from the register to select one of the data in accordance with a control signal. The counter generates the control signal for the selector so that plural items of data will be output serially from the selector in the sequence in which the plural items data have been serially supplied to the register.

Abstract: A destination for a job completion notification that is preset by a user is stored. When the user enters a detection area, an electromagnetic wave signal is transmitted to a memory card that is carried by the user so that the user identification information is scanned. When the job is completed, the job completion notification is transmitted to the stored destination for the job completion notification. Therefore, it is possible to transmit the job completion notification to a desired address even when the user instructs a job, such as copying job or facsimile memory transmission job, by directly setting a document on a multifunction apparatus.

Abstract: Print data for a mailbox print instruction given by a client PC is stored in a hard disk. At the same time, when a user enters a detection area, an electromagnetic wave signal is transmitted to a memory card carried by the user in order to retrieve the user's identification information. Based the retrieved identification information, the user is authenticated. Then, it is determined whether a mailbox print operation is requested in the personal information table. When requested, it is determined whether the print data of the user is stored in the hard disk. When stored, the print data is printed out through the printer.
