Provided is a communication system capable of enhancing convenience for remotely operating a movable-body-mounted apparatus mountable in a movable body such as a vehicle. For example, a communication system includes a movable-body-mounted apparatus including: a movable body information storage part which stores movable body information including a received signal quality of a radio wave used for communication to/from a center server and information on a vehicle; a separation determination part which determines whether or not a user who moves along with the vehicle is separated from the vehicle; and a movable body information notification part which notifies the user of the movable body information stored in the movable body information storage part when the separation determination part determines that the user is separated from the vehicle.

An electronic document authenticity assurance technique and an information disclosure system both of which can compatibly realize the assurance of the authenticity of disclosure documents and the deletion of information inappropriate for disclosure. An electronic document is divided into constituent elements and an electronic signature is affixed to an arbitrary subset of a set including all the constituent elements. Otherwise, an electronic signature is affixed to data obtained by binding each of the constituent elements to information specifying the relationship between a respective one of the constituent elements and the structure of the electronic document. Otherwise, the hash values of the respective constituent elements are calculated and an electronic signature is affixed to data obtained by binding the calculated hash values together. Otherwise, random numbers generated for the respective constituent elements are bound together, then the hash values of the respective random-numbered constituent elements are calculated, and then an electronic signature is affixed to data obtained by binding the calculated hash values together.

Electronic document authenticity assurance method and electronic document disclosure system

In an information distributing method, an information providing resource receives from an information user unit a request statement including a code to identify first information and information (URI) to identify second information quoted in the first information. According to the identifying information of the second information included in the request statement, the information providing resource determines whether or not transmission of the second information to an information providing unit is allowed. The information providing side can control the operation in which the second information thereof is quoted to be opened in the first information.

The problem is to make a reliability decision on printed matter without using special ink or a dedicated blank. At least a part of a feature of a state included in printed matter is recorded by using a predetermined method at the time of printing. At the time of verification, the feature of the state acquired from the printed matter is compared with the feature recorded at the time of printing to conduct verification. As this feature, a feature value determined on the basis of a feature of the state of the printed matter, in the state of the printed matter determined in association with spatial distribution of a coloring portion on the printing surface, at the time when printing first information to be recorded is used.

A search service provided by an electronic data search system including a search center and at least one authorization center. The search center receives a search request from an information browsing apparatus and in response searches for URLs that are associated with a search condition included in the search request in a search database that registers URLs of Web pages, associating those URLs with respective search conditions. The search center presents the information browsing apparatus with link information to the detected URLs. When the search request also includes a condition that authorization by the authorization center be given, then URLs that are registered in the search database associated with the search condition, and registered in the authorization center are searched. Link information of detected URLs is presented to the information browsing apparatus and the authorization center registers URLs of Web pages opened by information disclosing persons who have been given authorization.

System and method of searching for electronic data

An image data manipulation method and a recording medium for recording a processing program thereof are disclosed. A block to be manipulated is read out of the image data, and the DC component value of at least one of the luminance information and the color information is changed for each block, and the ID information for identifying the changed block is attached to the image data containing the particular block, thereby controlling the manner of display of the image data for each block.

Method of manipulating image data and a recording medium for recording a processing program thereof

It is an object to provide a computer system including a practical input device which can be operated with more natural sense. The present input pen which is used in combination with a tablet includes: a speech recognition unit for analyzing a speech sound, which is fetched in through a microphone, as a command or the like; an image reconfiguring unit for composing, after correcting image distortion generated due to inclination of the pen body for each image in the vicinity of a pen head which is photographed along with the strokes of the input pen by a CCD camera, the series of images into a general image; and a reference line generating circuit for lasing a laser beam with which a projected image utilized to calculate an angle of inclination is formed onto a face of an object of photographing. In addition, since an oscillation circuit generates a magnetic field corresponding to the data forming the general image on the basis of control by an a.c. magnetic field control circuit, the data can be transferred to the information processor side through the tablet. Further, a CPU executes the processing corresponding to the result of analyzing a sound.
