摘要： PROBLEM TO BE SOLVED: To enable a user to in alter proof information according to an inspector even after the proof information generating device is delivered to the user. SOLUTION: Proof information C and proof additional information (n) which are inputted from an input means 2 are passed to an arithmetic means 3. The arithmetic means 3 reads secret information (d) out of a secret information holding means 1 and performs specific operation by using the proof information C, proof additional information (n), and secret information (d). For example, the proof additional information (n) is inputted as the modulus number of an open key pair and the secret information (d) is used as an exponent to perform power-residue operation C mod (n). The proof information R calculated by the arithmetic means 3 is outputted by an output means 4. The inspector calculates R mod n by using the other key (e) of the open key pair pairing with the secret information and it is decided that the proof is obtained on condition that the proof information C is obtained.

摘要： PROBLEM TO BE SOLVED: To allow both a user side and a protecting side such as an application creator to unnecessitate to handle inherent information such as many authentication keys. SOLUTION: An access ticket generator 12 generates an access ticket from user's inherent information and the characteristic information of access right. As for characteristic information, the security key of an elliptic curve cipher or ElGamal cipher is used. A certification data generating device 11 receives an access ticket, further converts authenticating data that is received from an certification data verifying device 10 into certification data by using the access ticket and the user's inherent information and returns it to the device 10. The device 11 or the device 10 decodes the cipher. The device 10 verifies it as a correct access only when the combination of the access ticket (t) and user's inherent information (e) which are used in the device 11 is correct.

摘要： PURPOSE:To allow the device to rotate a window in a position easily observed by the operator according to the instruction of an electronic pen by entering angle information depending on the position wherein the electronic pen of the user is resident, with respect to the display device of the device. CONSTITUTION:An electronic pen detection section 12 arranged on a display screen of a display device 11 informs an processing section 17 of coordinate information representing coordinates entered by plural electronic pens 1-4 and identification information to identify each electronic pen. The user enters the identification information to the electronic pens 1-4 given in advance to the detection section 12. The user draws a slant of, e.g. 45 deg. by using the electronic pens 1-4 at its seated position. The slant is detected by the detection section 12 and converted into an angle from a reference position and stored in a drawing angle storage section 13. When each user instructs rotation by using its own electronic pen in the case of a conference, a window control section 15 processes the drawn picture information from the information processing section 17 to display the window in a direction easily observed based on the drawing angle information from the reference position stored in the drawn angle storage section 13.

摘要： PURPOSE:To naturally transfer and receive the right of device operation by displaying by mark a position by a coordinate indicating means on a display screen when the coordinate indicating means is made to come into contact or to approache on an inputting board during inputting of a coordinate position by plural coordinate indicating means. CONSTITUTION:Plural coordinate positions for the input board 12 by plural coordinate indicating means 13, 14 for indicating coordinate positions are indicated respectively and input operation for inputting the coordinate positions indicated by the means 13, 14 is performed by the input board 12. When plural coordinate indicating means 13, 14 come into contact or approach on the input board 12, a coordinate position detecting means 15 extracts the coordinate position data of the means 13, 14 and a coordinate conversion means 16 converts the coordinate position data extracted by the means 15 into one coordinate position data. A mark display means 11 displays a mark 18 on a display position corresponding to the coordinate position data converted by the means 16 on the screen of the device 11. Consequently the cursor operation right can be clearly and naturally transferred between plural persons.

摘要： PURPOSE:To improve a speed for display and data transfer and to easily execute preparation and edition, etc., of a sentence by fetching a printed matter, etc., as character data to a work station. CONSTITUTION:A still picture input device 201 projects the sentence on the printed document and original by character and picture camera and fetches a picture signal for one frame to a frame buffer memory 202 by a freeze signal while displaying the picture data on a display 207. When the picture displayed on the display 207 is observed and a necessary character area is set by an area setter 204, an area segmenting part 303 segments only the set area and a character recognition part 205 converts the picture data to character data and sends the data to a work station 206 which can execute editing operation. Thus, the speed for the display or data transfer is improved and the preparation and edition, etc., of the sentence can be easily executed.

摘要： PURPOSE:To accurately control the moving distance of a recording head and to prevent a white stripe or superposition of a recording image by detecting the moving distance of the recording head on the basis of an output from an ink droplet detector. CONSTITUTION:An ink droplet is flown from a nozzle 2 at the left end of a drop generator 1 to a stitch point of its left end, and it is repeated until the output voltage from a signal processor 14 becomes equal to 0V. Thus, the ink droplet from the nozzle 2 of the drop generator 1 is flown to the stitch point in a state that a carriage 10 is moved by one step, the flying position of the ink droplet is detected by an ink droplet detector 6, the moving distance of the carriage 10 is detected, and so controlled that the moving distance becomes a predetermined value. Thus, it can be so controlled that the moving distance of the carriage 10 becomes equal to a predetermined value without newly adding a hardware for detecting the moving distance of the carriage 10.
