Abstract: A communication terminal includes a memory in which identification information associated with a user is stored, a controller that carries out authentication of the user, and a communication interface that transmits a signal including the identification information. When user authentication is successful, the controller sets the communication terminal to a first state in which the signal is transmitted to an external apparatus, and when user authentication is not successful, the controller sets the communication terminal to a second state in which the signal is not transmitted to the external apparatus.

Abstract: A wearable computer includes: a first storage that permanently stores a first characteristic therein, the first characteristic representing a physical characteristic of an owner of the wearable computer; an obtaining portion that obtains a second characteristic, the second characteristic representing a physical characteristic of a user who wears the wearable computer; a determination portion that determines whether the user is the owner based on the first characteristic and the second characteristic; a first request portion that requests, when the user is determined to be the owner, to allow the user to log into another device; a second storage that temporarily stores the second characteristic therein; and a second request portion that requests, when the user is not determined to be the owner, to allow the user to log into that another device by sending the second characteristic stored in the second storage portion to that another device.

Abstract: A terminal device includes, as functions for transmitting a file with a digital signature via mail, a first communication unit for carrying out communication with a terminal device used by an authorizer when a distance from that terminal device is not greater than a prescribed distance, an obtaining unit for obtaining a value obtained from a file to be transmitted, which has been encrypted through encryption processing performed by making use of information exchanged with that terminal device, and a transmission instruction unit for outputting an instruction for mail transmission of the file and the obtained encrypted value.

Abstract: A portable authentication device is provided. The portable authentication device includes: a sensor that detects a biometric information of a subject; a communication interface that communicates with another authentication device; and a hardware processor. The hardware processor executes a first authentication process using the biometric information, and transmits the biometric information to the other authentication device via the communication interface to cause the other authentication device to execute a second authentication process. When the subject is authenticated by the second authentication process as being valid and while a predetermined condition is satisfied, the hardware processor transmits to an apparatus an information to cause the apparatus to authenticate the subject when the subject is authenticated by the first authentication process as being valid.

Abstract: A portable terminal includes a hardware processor, a storage, a communication interface that communicates with an external device, and a sensor that detects a subject's biometric information. The external device includes an authentication device that executes an authentication process using the biometric information to authenticate the subject. The external device transmits information based on the authentication process to the terminal authentication to obtain a permission to operate an apparatus. The hardware processor transmits the detected biometric information to the authentication device, receives the authentication information from the authentication device, stores the received authentication information in the storage, sets the storage to a state where the authentication information is readable when a predetermined condition is satisfied, and sets the storage to a state where the authentication information is unreadable when the predetermined condition is not satisfied.

Abstract: In order to prevent a duplicate of a still image from being generated, an MFP includes an image obtaining portion to obtain one or more still images, a moving image generating portion to generate a moving image in which the obtained still images are displayed sequentially, and a distribution portion to perform real-time streaming distribution of the moving image in response to a request from a PC connected to a network.

Abstract: An information processing apparatus includes an executing unit executing information processing, a control unit controlling an operation of the executing unit, a storage unit for storing specific information for executing an administrator mode and a communication unit for communicating with a smart card. When information matching the PIN code stored in the smart card and information matching the information stored in said storage unit are received, the control unit executes the administrator mode.

Abstract: An image processing apparatus includes: a key creator that creates one set of a secret key and a public key for each user; a reader that reads out an electronic certificate to certify a user, created by a certificate authority, and the user's own secret key, from a portable recording medium having this electronic certificate and the user's own secret key recorded therein; and a certificate creator that creates an electronic certificate including the public key created by the key creator, by giving a signature using the user's own secret key read out by the reader.

Abstract: A data output control method, where plural output apparatuses and an information processing terminal are connected via network, for outputting job data, from the information process terminal onto the output apparatuses, the method including the steps of: generating an output instruction at an information processing terminal for outputting job data onto an output apparatus selected by a first selection method; withholding transmission of the job data to the output apparatus until the output apparatus becomes capable of processing the job data, and obtaining a first authentication information for specifying a user, and storing it by correlating with the job data; obtaining second authentication information for specifying a user who has conducted the second selection operation of the output apparatus; comparing the first and second authentication information; and accepting a change operation, when they are identical.

Abstract: After receiving job data from an information processing terminal, job data wherein an output device is designated as an output destination, a server preserves therein the job data until the moment when an output processing for the job data becomes practicable on the device of the output destination, then, creates second job data representing a replication of the job data before the transfer of the job data to the output device is started, and it conducts changing process for the second job data representing a replication, when it receives an instruction for changing an output destination and output setting, after the transfer. Further, the job data are preserved in the output control server until the moment when the print processing is completed at the output destination, so that they may cope with changing operations for a period up to completion of printing.
