摘要： PROBLEM TO BE SOLVED: To prevent a user from copying illicitly the original information based on the purchased encipherment information by using an external device to decode the enciphered distributed information, to embed a user authenticator into the decoded original information and also to manage the keys which are used for both decoding and embedding processes. SOLUTION: This original information protection device (external device) 50 consists mainly of an information decoding part 57 and an information embedding part 58. When the device 50 is produced, a master key that is inherent to the device 50 is stored in a master key storage part 54 of a security device 52. At an enciphering/decoding part 55, a user's secret key is enciphered by the master key that is stored in the part 54 and this enciphered key is stored in a storage part 59. The control part of a user terminal receives the enciphered key via an open key and sends this received key to the device 50. A terminal input/output control part 51 of the device 50 sends the received key to a control part 53.

摘要： PROBLEM TO BE SOLVED: To reduce time and the cost of transfer by compressing and ciphering card information when the card information is transferred. SOLUTION: All pieces of information required for an authentication processing from a card inserted and set in a card utilization terminal 10 is read from a card information input/output part 11. One of plural compression means is selected and compressed by a control part 21 of a compression and ciphering device 20. In this case, a process to execute compression is held in a compression means storage part 23 by providing plural generally used reversal compression means, or the card utilization terminal 10 and an authentication center with the same code list. When data length of the data after compression is equal to 128 byte or more, another compression means is selected and the data is compressed again by the control part 21 and after the data is compressed to the data length of 128 byte or less, the card information is ciphered with a ciphering key described in a ciphering key storage part 25 by a card information ciphering part 24. The compressed/ciphered card information is transmitted from a communication input/output part 13 to a communication route by a communication control part 12.

摘要： PROBLEM TO BE SOLVED: To provide the method and device for cipher authentication which enables only proper users to use cipher systems without making secret information in a cipher device leak to a 3rd party, and enables the systems to function at the same time by more than one application system. SOLUTION: A user inquires a cipher system of a cipher system management part 19, sets a use mode in a communication control part 11 to start communicating, and sends the user ID to an access control part 12. The access control part 12 gives the user the right to access secret information only when the user ID matches the user ID stored in a secret information storage part 23. The user accesses open information and the secret information by the given right to access, and performs a key generating process and a cipher authenticating process.

摘要： PURPOSE:To decide time and time length for transferring information and the number of optimum lines required for transmission by selecting the time length up to the end of communication according to the intention of an operator while previously grasping the capacity of information to be transmitted. CONSTITUTION:A user is provided with the transfer information name of input information, destination and transmission destination information name corresponding to instruction inputs and calculates a communication distance by retrieving and analyzing the table of communication distances previously stored in a recording part 200 from the line numbers of the opposite side and present user terminals under the control of a control part 202. Next, the unit time of one line is calculated from the time of a clock 203 in the case of previously inputting and indicating the communication distance. Afterwards, a transmission amount per unit tariff is calculated from the table of transmission speed per unit time stored in the storage part 200 for each of menu designation information corresponding to each channel in order to calculate the transmission amount for each line from the unit time, and an output menu picture is prepared. Then, the number of channels to be secured is calculated for enabling economic and high-speed communication and corresponding to the capacity of desired information to be transmitted, the time length required for exchanging the information can be recognized in advance.

摘要： PURPOSE:To speed up the diagram recognizing process and minimize a recognizing circuit in size, by calculating in advance a point string constituting a diagram element to be approximated, and by judging an error between the point string and that to be recognized. CONSTITUTION:The value of a single-value function f(xn) is stored in a register 4 from a register 2. The value of another single-value function g(xn) is calculated at a simultaneously calculating circuit 3 and the value is stored in a register 5. A calculation¦f(xn)-g(xn)¦is executed by an operation circuit 6 and the result is represented by epsilon. The value epsilon is compared with a threshold E stored in a register 8 by a comparator 7. The comparator 7 judges the result of the comparison, and, if epsilon E, it judges that a point row F cannot be approximated by a point string G. When all the calculations on (n) pieces are completed at the circuit 3 and the above mentioned operations are completed, it is judges that the point string F can be approximated by the point string G.

摘要： PURPOSE:To make it possible to make a correction as indicated to a picture-element unit by enlarging and displaying partially a pattern picture on a display screen which an operator indicates. CONSTITUTION:Input pattern 11 of a drawn triangle shape is read by pickup part 12, A/D-converted 13 and then stored in digital memory 15; once an operator indicates the entire picture by input signal S1, the side of lattice pattern generating circuit 30 is selected by selector circuit 33 and picture 40 can be obtained at display part 25. In order to make the correction of the blur of the triangular pattern at the part of picture 40 indicated by P, the operator gives input signal S2 coordinates of x=3 and y=4 of part P, so that pattern information in the corresponding address will be read out to memory 15. Here, the operator changes a switch over to enlargement for selective input S1 to enlarge part P over the entire screen (screen 50); at this time, a defect is also found in part Q, and signal S2 is given coordinates of m=6 and n=3 after it is confirmed that this part is not in white but in black, thereby completing the correction as shown in pattern 60.
