TL;DR: In this paper, a keypad is employed to input the stimulus output from the computer (34, 68) into the access key (12), which allows for secure communications between different computers and between distant locations.
Abstract: A semiconductor device that functions as a key (12) to control access to a computer (34) or a software program resident in a computer or provides for secure communications. The device (64) executes an algorithm that combines a root and a seed to produce a password. The password is input to the computer (34). The computer (34) uses an equivalent algorithm to produce a password within the computer (34). Comparison or other methods are employed to allow access to the computer (34) or computer program or to allow for secure communications. The computer (34) can be coded to produce on a video display (18) thereof a time-space stimulus pattern which can be received by sensors (28a-28d) of the key. Alternatively, a keypad (700) can be employed to input the stimulus output from the computer (34, 68) into the access key (12). Further the present system allows for secure communications using algorithms between different computers and between distant locations.

18 Feb 1986TL;DR: In this article, a high security and rewritable IC card has a microprocessor, a memory, and a keyboard, and the memory has a password registration area, an error counter area in which the number of occurrences of an error in inputting a password is stored, and card information area.
Abstract: A high security and rewritable IC card has a microprocessor, a memory, and a keyboard. The memory has a password registration area, an error counter area in which the number of occurrences of an error in inputting a password is stored, and a card information area. The microprocessor controls a password registration operation, registers the password inputted through the keyboard in the password registration area. When the registered password is to be updated, the microprocessor clears the password registration area in the memory to allow writing of a new password only when the microprocessor detects that a password data inputted by a card user matches the registered password and the error count in the error counter is no more than a predetermined count.

TL;DR: In this paper, a data communication system, plural telephone lines are divided into a registered group and a non-registered group, and the registered telephone numbers and the passwords of the associated remote terminals are stored in a memory.
Abstract: In a data communication system, plural telephone lines are divided into a registered group and a non-registered group. Authorized remote terminals are respectively associated with the telephone lines of the registered group. Each remote terminal transmits a password when it accesses to the central station from the associated, registered telephone line. The password is appended with an extra code when the access is made from a non-registered telephone line. The registered telephone numbers and the passwords of the associated remote terminals are stored in a memory. A coincidence between the password transmitted from a remote terminal and a stored password is detected to proceed with the detection of whether the transmitted password is appended with an extra code or not. In the absence of the extra code, the central station calls back the remote terminal using a telephone number stored in the memory in association with the transmitted password. If an extra code is appended, the remote terminal is requested to inform the central station of the non-registered telephone number to allow it to call back the remote terminal.

Abstract: PURPOSE:To change a station which is charged by transmitting an outgoing and incoming call conversion request, the telephone number of an origination side, and a password predetermined between the origination side and a termination side from the origination side, and calling the origination side automatically from the termination side after the termination side confirms the password and disconnects the circuit. CONSTITUTION:The origination side sends out an identification signal for setting a nonstandard device, reports the request for outgoing/incoming call conversion and the password for said conversion, and also sends its dial number in specific pattern. The reception side, on the other hand, decides the password for outgoing/incoming call conversion, and then returns a signal for reception preparation confirmation and stores the dial number of the originating station when the password coincides with a previously specified password. In this case, the origination side sends out a circuit disconnection command and disconnects the circuit. The termination side performs the outgoing/incoming call conversion after the circuit is disconnected and dials the dial number stored during nonstandard device setting reception automatically, and follow a normal facsimile procedure thereafter.

TL;DR: In this paper, the check between the password number read out from a ROM and that from a reader/writer is performed, and it is decided that the presenter of the IC card is a principal when coincidence is obtained.
Abstract: PURPOSE:To protect an IC card from a crime, such as forgery, or theft, etc., by performing the check of a secret proper number after the check of a password number. CONSTITUTION:At an IC card side, the check between the password number read out from a ROM and that from a reader/writer is performed. As a result of check, it is decided that the presenter of the IC card is a principal when coincidence is obtained. Next, at a reader/writer side, the secret proper number stored at the ROM is read out, and it is outputted to the IC card side. At the IC card side, the secret proper number is read out from the ROM, and it is checked with the proper number from the reader/writer side. When the coincidence is obtained as the result of check, it is decided that the IC card itself is a true card, and a bit of information to permit the use of the IC card is outputted. In this way, it is possible to protect the IC card from the crime, such as the forgery, or the theft, etc.

TL;DR: In this article, an IC card 8 is put into a card reader 7, and a password number input key K is operated for input of said number, then the 1st signal circuit 12 produces a single pulse if the password number is correct.
Abstract: PURPOSE:To prevent a foul bank transaction by using an IC built-in card (IC card) which is not altered easily as well as a password number. CONSTITUTION:An IC card 8 is put into a card reader 7, and a password number input key K is operated for input of said number. Then the 1st signal circuit 12 produces a single pulse if the password number is correct. This pulse is applied to a 1-bit memory circuit 19, and a pulse train is delivered through an AND gate 21 when the output of a reverse gate 20b is equal to '1'. The pulses of said train are applied to a memory DM as the timing signals and also counted by a counter 22. Then the using times of the card 8 are counted. While the reader 7 detects that an IC10 of the card 8 had the correct working according to the input password number. Thus a normalized transaction is carried out only when the card 8 is recognized as a correct one.

TL;DR: In this article, when a password number fails to be inputted continuously four times, a counter register 16 counts up to '4' and a '1' signal is outputted from an output line 16a.
Abstract: PURPOSE:To use efficiently a P-ROM whose capacity is limited by writing data at a stored bit area location without succession when a correspondence result is obtained as a result of password number matching and writing the data at a bit area location which is one higher than the stored bit area location when the correspondence relation is not obtained. CONSTITUTION:When a password number fails to be inputted continuously four times, a counter register 16 counts up to '4' and a '1' signal is outputted from an output line 16a. At this time, a dissidence signal is supplied from a control part 17 to an AND circuit 22, so the output of the AND circuit 22 is '1', which is sent as a buzzer signal to the control part 17. Consequently, the control part 17 gives a warning to a user. Further, if the next password number also fails to be inputted, the register 16 counts up to '5' and the '1' signal is outputted from an output line 16b and sent to the control part 17 through an AND circuit 23. The control part 17 when supplied with the '1' signal from the register 16 through the AND circuit 23 writes all-'0' data in the final address N of an RN storage area 20a to make the IC card 10 permanently ineffective.
