An information management method and an information processing device functioning as a node are provided to enable an effective use of information distributed to, and shared with, a plurality of nodes on a network and to enable maintenance of security against leakage of information by controlling information retention. This management method of information gathers information distributed to, and shared with, a plurality of the nodes on a network and holds the information in a state accessible from other nodes to a temporary information memory unit when generating restored information. The information management method is also characterized in setting a flag for showing a history of the information and immediately discarding the information in the case that the retention of restored information becomes improper from a view point of contents of the flag.

Authentication processing is easily performed on a device used as a node in a network. Upon the authentication of a terminal used as the node in the network, when the terminal can communicate with another terminal, the terminal sends an electronic certificate of the terminal per se to the other terminal and requests the other terminal to perform an authentication process of the terminal per se. Conversely, when the terminal cannot communicate with any other terminal, the terminal outputs the electronic certificate of the terminal per se to an authentication device and requests the authentication device to perform authentication of the terminal per se. The authentication device performs authentication of the terminal based on the outputted electronic certificate.

Provided are an authentication method, authentication system and a terminal device in which the authentication of a non-participating third node is can be simplified and can be executed in the case of multicast by using an authentication ticket in a distributed processing network system, the non-participating third node being intended to access each of the nodes, including a first and a second node, constituting a workgroup. The first node that has already participated in the workgroup authenticates the third node intended to participate in the workgroup and issues the authentication ticket including the signatures of both nodes, and when the authentication ticket is submitted to the second node, the second node permits the third node to access, without password-based-authentication, by authenticating the first node and the second node which have signed the authentication ticket.

A network management method and system is provided that issues a digital certificate easily and safely. A digital certificate is issued to a personal computer that is to newly join a network by the following method. A provisional authentication server issues a first digital certificate that is a provisional certificate of the personal computer. The personal computer enters the first digital certificate and a private key corresponding thereto. The personal computer and a formal authentication server establish a connection for encryption communication based on the first digital certificate. After establishing the connection, the formal authentication server generates a second digital certificate that is a formal digital certificate of the personal computer. Further, an experimental network independent of the network is prepared and participation of a personal computer having the first digital certificate into the experimental network is allowed.

A multi-tone image processing method and apparatus in which mutually dissimilar tone levels are realized by changing the additive condition of recording energy by means of different recording positions, even when the number of recording operations within a specific range is identical. For example, in an electrophotographic apparatus, when the number of irradiation by a light spot within a specific range remains constant as the irradiation position is changed in the specific range, there is a change in the additive condition of the optical energy within said specific range. Thus, the area rendered visible within the aforesaid specific range also changes, thereby changing the tone level.

Multi-tone image processing method and apparatus

In an image-processing employing a dither matrix a basic dither pattern is formed of a set of a plurality of basic patterns each including a plurality of pixels. In a single basic pattern a single pixel is assigned 1 serving as a number indicating an order followed to illuminate a dot in the dither matrix. When basic dither patterns are arranged longitudinally and laterally a location remotest from any pixel assigned a number is selected and a pixel at that location is assigned a subsequent number. This series of operations is repeated. When there is no basic pattern that is not assigned a number, in basic pattern a number indicating an order followed to illuminate a dot is assigned to allow the dither matrix to a dither matrix of dot convergence type. Thus a dither matrix allowing an image processing apparatus to satisfactorily reproduce an image can be created.

An image processing apparatus providing a halftoning process such as error diffusion prevents an image contour distortion, as follows: data in an image to be processed is used to partially extend the image to be processed. Then error diffusion or the like is employed to provide a halftoning process. The extension is removed to obtain image data. A dot generation delay can be prevented that would otherwise be introduced such as when an extension-free image is halftoned.

From profiles of an input color space and an output color space, the specific color data on respective color spaces are obtained, and a color space compression parameter is set based on each specific color data obtained. In other words, the color space compression parameter for appropriately converting data within the input color space into data within the output color space is derived from each specific color data. The color space compression processing (color matching) is performed on an absolute color space using the derived color space compression parameter so that it becomes possible to perform at a higher speed an appropriate color matching that takes into account the characteristics of the input color space and the output color space.

Color matching method and device, color matching program, and computer readable record medium that stores color matching program allowing appropriate color matching at high speed

The gray axis of an input apparatus is shifted so as to match the gray axis of an output apparatus. Each data on a plane of equal lightness located in the Gamut of the input apparatus is shifted in the same direction in accordance with the shift of the gray axis by an amount of shifting smaller in proportion to greater distance from the gray axis. Therefore, the image is not governed by the chromaticness in the shifting direction even if the gray axis is shifted. Points located outside the Gamut of the output apparatus is compressed-converted into points within the Gamut (surface) where color difference is minimized while maintaining the lightness. A desired image is reproduced without inversion in the lightness after Gamut compression between data.
