  • Patent number: 9723579
    Abstract: A traffic data integration method includes: obtaining, by using a computer, pieces of frame data having a same data pattern between first and second traffic data collected respectively by first and second capture devices that capture, as traffic data, frame data communicated by a node in a network; performing, by using the computer, a time correction process by which a time of each piece of frame data in the first and second traffic data is corrected so that capturing times of pieces of obtained frame data are identical; using, by using the computer, frame data for which a same data pattern does not appear repeatedly in a same capture device, as frame data for performing the time correction process; and restricting, by using the computer, a time difference of frame data used when the time correction process is performed.

  • Publication number: 20080010673
    Abstract: An authentication system performs user authentication between a client and a server using a one-time password. Each of the client and the server generates random authentication data. The generated random authentication data is exchanged between the client and the server. In this way, authentication based on a complete random authentication data not using specific one-time password generation logic can be provided. Furthermore, by applying the method for authentication and the method for updating a one-time password according to the present invention, spoofing can be detected even when a password is stolen. As a result, unauthorized access can be prevented.

  • Publication number: 20060025107
    Abstract: In a portable-terminal usage management method, log distribution conditions are downloaded from an administrative function module to one of a plurality of portable terminals. One of a plurality of communication log storage parts is selected in accordance with the log distribution conditions whenever one of the plurality of portable terminals starts communication. A communication log related to the communication started by the one of the plurality of portable terminals is stored into the selected one of the plurality of communication log storage parts.

  • Patent number: 6552737
    Abstract: A device for controlling multi-window display on a screen includes a screen-operation detecting unit which detects user screen operations including a user operation of a pointer on the screen. The device further includes a control unit which controls a window to increase an amount of information displayed therein when said screen-operation detecting unit detects a move of the pointer into an area of the window.

  • Patent number: 6484128
    Abstract: A data processing system which provides increased reliability by properly managing a plurality of basic modules. System configuration data is a collection of information regarding basic modules constituting each target system. Compatibility data is compiled to keep statistics of past failures occurred in a target system, which maintains the following associated records: properties of failed basic modules, properties of their related modules, failure types, and failure counts. When a basic module is changed in a target system, the target system sends out a notification message. This message is received by a notification message parser and supplied to a system configuration manager via a hardware change manager. The system configuration manager first consults the system configuration data to identify the changed basic module and its related basic modules, and then retrieves information about compatibility of such basic modules by consulting the compatibility data.
