  • Patent number: 4357529
    Abstract: A card-encoding system and method preserves the security of the encoding process against duplication and counterfeiting of cards by securing the interactions under the control of the individual and then of the issuing institution. Multilevels of offset codes are generated in successive interactions so that attempted alteration, duplication, or counterfeiting of a coded card will be readily detectable using "off-line" card-checking apparatus. An "active" card is initially issued or authorized with an established credit balance, and its authenticity, balance, and proper use are continuously checked, debited and updated in each authorized transactions completed by the proper individual. A card or other data-carrying medium may be verified as authentic and unaltered, and the identity of an authorized individual assigned to the card may be verified by initially recording an offset on the card and by subsequently comparing the recorded offset with an offset regenerated from the same data used initially.

  • Patent number: 4315101
    Abstract: A method and apparatus are provided for improving the security of data transmissions between stations and for controlling secured transactions from remote locations in a data-transfer system. The method and apparatus obviate the need for transmitting user-identification information such as personal identification number (PIN) from station to station, e.g., from the station utilized by the user to enter his PIN and initiate a transaction, to the station that processes the transaction. Also, for added security, the method and apparatus provide for encryption (encoding) and decryption (decoding) of data during a transaction using encryption and decryption keys produced from different (independent) PIN's. The apparatus includes at least one irreversible algorithm module, a random number generator and at least one data file (e.g., disc or magnetic tape storage). The apparatus also includes a comparator or, alternatively, an encoding algorithm module and a matching decoding algorithm module.

  • Patent number: 4288659
    Abstract: An improved secured data transmission system relies on the favorable comparison of coded signals derived from information about authorized individuals and particular data terminals that is both prestored and subsequently supplied under manual command in order to generate an operating key which is then used to encode and decode data that is entered after the initialization procedure.

  • Patent number: 4198619
    Abstract: A code-word security system uses a logic module which can receive an account code word (or any other data that is specific to an individual) and a secret code word from an individual for encoding in accordance with a logical combination of such code words altered in accordance with a selectable control word to produce a compiled code word of fixed length. Such compiled code words may be stored and retrieved for comparison with a compiled code word similarly generated during the course of an authorized transaction by such individual, or may be transmitted with coded information and other data pertaining to such authorized individual for logical manipulation.

  • Patent number: 3938091
    Abstract: A customer code word issuing machine is provided wherein a customer manually inputs to the machine his secret password. The machine encodes the password and displays his corresponding issued code word. A verification machine is provided which includes a dial or keyboard for manually inputting the customer's password and the issued code word. The verification machine encodes the inputted password to derive an output for comparison with the manually inputted code word to derive an output indicative of the truth or falseness of the match of the code word with the respective password. The verification machine may be employed to open a lock, to allow use of a credit card for a telephone call, purchase of goods, etc.
