Abstract:
A method for recognizing a cipher, said method comprising:associating said cipher with a plurality of cells of a matrix having N rows and M columns, with each of said plurality of cells having a plurality of pixels corresponding thereto, with a subset of said plurality of pixels, of a subgroup of said plurality of cells, having a portion of said cipher associated therewith, defining a plurality of portions of said cipher, wherein subsets of said plurality of pixels having a number of pixels associated therewith in excess of a number of pixels associated with the remaining subsets, defining remainder pixels, are positioned in predetermined cells of said matrix;determining whether each of said subset of pixels includes an equal number of pixels;assigning a binary state identifier with each cell of said plurality of cells;assigning a digital word to said matrix, with said digital word being a function of the binary state of said plurality of cells, wherein said assigning includes forming digital data which corresponds to said predetermined position, with said digital work including said digital data;comparing said digital word with information in a look-up table, said information including a plurality of known ciphers, each of which includes a corresponding digital representation; andproviding the known cipher corresponding to the digital representation in said look-up table that most closely matches said digital word.
