Abstract:
A digital measurement apparatus measures a physical measurement object, provides a digital signature of public-key cryptography to measured data of a thus-measured physical quantity, and manages the measured data. The apparatus generates at least a pair of a public key and a private key, to be used for the digital signature of the public-key cryptography, through a key generating algorithm.
Abstract:
A charge management system includes a user managing unit configured to manage pieces of user identification information for identifying users and pieces of terminal identification information for identifying transmission terminals, each piece of user identification information being associated with pieces of terminal identification information for identifying transmission terminals used by a user identified by the each piece of identification information; and a calculating unit configured to calculate a participation charge to each of the transmission terminals, bases on a total participation duration in which the each of the transmission terminals has participated in a conversation during a predetermined period, and calculate a total participation charge to each of the users by summing up the participation charges to transmission terminals specified by the pieces of terminal identification information associated with the each piece of the user identification information.
Abstract:
A text print instructions sheet generation unit embeds, in a text print instructions sheet, identification information for specifying a text print instructions sheet after being converted into image data. A sheet data management unit manages layout information that associates the identification information for specifying the text print instructions sheet with the identification information of a document included in a retrieval result. An image analysis unit extracts the identification information for specifying a sheet from the image data, specifies the layout information managed by the sheet data management unit based on the extracted identification information, and performs image analysis based on the specified layout information.
Abstract:
In a computer to support security of information, a user authentication request is received as a request of remote operation call through a network, a user using an external application program is authenticated based on the user authentication request. An authentication result capable of detecting a falsification is generated, and the authentication result is returned as a response of the remote operation call to a request originator through the network.
Abstract:
A scanner device that optically reads an image comprises a protect specification data detection unit that detects a protect specification data which is contained in the read image to request protection of image data of the image. A protected image data creation unit encrypts the image data of the image containing the protect specification data, in response to a detection signal of the protect specification data detection unit that indicates that the protect specification data in the image has been detected, so that a protected image data is created.
Abstract:
A document security system is disclosed. In the document security system, when a user is permitted to use a device and to use a document, a process for the document requested by a user is executed by the device. Further, after executing the process, a follow-up obligation is executed corresponding to the type of the document obtained from image data of the document.
Abstract:
A maintenance mediation apparatus mediating maintenance operation instruction information in which a maintenance center gives an instruction for a maintenance operation to a corresponding one of maintenance target apparatuses connected thereto through a network is disclosed. The maintenance mediation apparatus includes a reception part receiving the maintenance operation instruction information from the maintenance center; a maintenance policy database storing a maintenance policy defining at least one of whether to authorize the maintenance operation on the corresponding maintenance target apparatus by the maintenance center and whether to authorize transmission of each item of usage condition information of the corresponding maintenance target apparatus to the maintenance center; a determination part determining whether to execute the maintenance operation referring to the maintenance policy database; and a transmission part transmitting the received maintenance operation instruction information to the corresponding maintenance target apparatus based on the result of the determination by the determination part.
Abstract:
A network communication device is connected to a maintenance center through a network and comprises a maintenance policy database in which a maintenance policy is stored, the maintenance policy specifying either transmission of maintenance information related to maintenance of the network communication device or a maintenance operation of the network communication device requested by the maintenance center. A maintenance information transmitting unit transmits the maintenance information to the maintenance center by referring to the maintenance policy database. A maintenance operation command receiving unit receives a maintenance operation command requested by the maintenance center. A maintenance operation control unit performs the received maintenance operation command by referring to the maintenance policy database.

Abstract:
An access control list attaching system in which an original content creator terminal for creating original content data, a policy server producing a security policy file concerning the original content data and holding it in a storage part and a right management server managing a right concerning the original content data are connected via a communication network. The policy server includes an access control list generating part generating an access control list concerning the original content data based on an attribute of the security concerning the original content data and the security policy file in which the security policy is described.
