Abstract
Abstract A system for recognizing the content of a communication in symbolic language and composed of plural glyphs arranged in a predetermined order, each glyph being the smallest (lowest) informational unit of the language. The system includes a device for inputting a stream of data indicative of the plural glyphs, such as formed in a page of text. That stream is input into a storage means. The stored data is horizontally segmented into discrete lines of text and is then vertically segmented into individual glyphs. Each individual glyph is assigned a unique identifier, whereby all substantially identical glyphs are represented by the same identifier. The identifiers are arranged in a sequence corresponding to the sequence in which the glyphs appeared in the communication, thus representing glyph "words". The system then applies decryption routines which include general cryptographic techniques to the identifiers, their sequences and their interrelationships to determine the equivalent symbol of language corresponding to each identifier. Once the symbol of language corresponding to each identifier has been determined, the machine code equivalent (i.e., code capable of being "understood" and utilized by an electronic computer) is substituted for each identifier, so as to provide a machine readable code representation of the communication, e.g., page of text.
