Abstract
A card having randomly-oriented optical ports and a system having a card reader for reading the card and having a keyboard for entering secret user-identification data are disclosed for securing the user-identification data entered into the system. The system includes a logic unit for controlling the keyboard, and for applying data to the card via the card reader. The system may also include a physical data collector or transducer for collecting fingerprint or voice-print data, or the like, from a user and for applying such data in digital form to the card via the logic unit and the card reader. The card operates in conjunction with the logic unit of the system to transform the applied data and to improve the security of said data. A method of fabricating the card and a method of securing entered data using the card are also disclosed.
