System for encoding data in machine readable graphic form
First Claim
1. A method of operating a facsimile communications system for transmitting a document to a destination, comprising the steps of:
- entering transmission information including a destination telephone number on a keyboard;
converting said transmission information into a two-dimensional bar code representation;
affixing said two-dimensional bar code representation of said transmission information, including the destination telephone number, to said document;
scanning said document, including said two-dimensional bar code representation affixed thereto, and producing signals representing said transmission information; and
transmitting said document to said destination in accordance with said signals representing said transmission information, including the destination telephone number.

Abstract
A system for representing and recognizing data in machine readable graphic image form in which data to be encoded is entered into the system and a processor encodes the data into a two-dimensional pattern of graphic indicia and generates transfer drive signals representative of the indicia. A transferring device such as a printer transfers an image of the two-dimensional pattern of graphic indicia onto a carrier such as a card or paper document in response to the transfer drive signals. A recognition device converts the image on the carrier into electrical signals representative of the graphic indicia and decodes the signals into output signals representative of the data for further processing or use.

4. A system for secure transmission of data from a first station to a second station comprising:
encoding means in said first station including means for entering data, means for encrypting at least some of said data using an encryption algorithm based upon an encryption key, means for representing said encrypted data in the form of a two-dimensional bar code structure, said bar code structure including a plurality of ordered, adjacent rows of codewords of bar-coded information, each of said codewords representing at least one information-bearing character, and means for transferring an image of the two-dimensional bar code structure onto a carrier; and
decoding means in said second station includingmeans for scanning the two-dimensional bar code structure and converting the codewords into output signals representative of said information-bearing characters, and means for decrypting at least some of said information-bearing characters using a decryption algorithm based upon said encryption key. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)
