Claim One:
1. A method for generating an unforgeable printable image containing embedded printable information data, comprising: encoding predetermined information as an array of information fields (Ixy), wherein each information field (Ixy) is assigned a binary value of 1 (one) or a value of 0 (zero), according to an encoding rule; defining an image area (R 0 ) comprising a stored printable image or a portion thereof; dividing said image area (R 0 ) to form a plurality of first regions (R 1 ) within image area (R 0 ); subdividing each of said first regions (R 1 ) to form a plurality of second regions (R 2 ) within each first region (R 1 ); assigning, according to a field assignment rule, each of said information fields (Ixy) to at least one of said second regions (R 2 ) within each of said first regions (R 1 ), and an interference field (Sxy) to the remaining second regions (R 2 ) within each of said first regions (R 1 ); assigning, according to an information color value assignment rule, a first information color value (IF 1 ) to information fields (Ixy) assigned a value of 1 (one) by said encoding rule, and a second information color value (IF 0 ) to information fields (Ixy) assigned a value of 0 (zero) by said encoding rule; assigning, according to an interference color value assignment rule, a first interference color value (SF 1 ) or a second interference color value (SF 2 ) to said interference fields (Sxy); and storing said unforgeable printable image containing embedded printable information data, comprising said stored printable image; said image area (R 0 ); said first regions (R 1 ); and said second regions (R 2 ) having said assigned first information color values (IF 1 ), second information color values (IF 0 ), first interference color values (SF 1 ) or said second interference color values (SF 2 ).
