A two-dimensional, high-density, damage-tolerant printed code suitable for
encoding multiple biometrics and text for positive off-line identity
verification comprises a horizontal header section; a vertical header
section; a start pattern; a left row address pattern; an encoded data
portion; a right two address pattern; and stop pattern. The horizontal
header section encodes the number of bit areas in a transverse row of the
encoded data portion; and the vertical header section encodes the vertical
height of each bit area. The start and stop patterns of the code demarcate
the lateral extent of the code (i.e., the beginning and end) from the
adjacent quiet zone. Information is encoded into the ended information
portion in bit areas that may be printed or blank. The information is
encoded sequentially in the information portion from the top of the
encoded information portion along each transverse row of bit areas to the
next row of bit areas until the end of the encoded information portion.
Error correction is applied to subunits of information from the encoded
information portion by dividing the user messages and applying error
correction to subunits of the user message. The two-dimensional,
high-density, damage-tolerant printed code is suitable for printed on a
conventionally sized ISO cord or other papers used in verifying identity.
An ISO-sized cord or other identity paper bearing a two-dimensional,
high-density, damage-tolerant printed code encoding multiple biometrics,
e.g., encoded image likeness and multiple finger print templates, maybe
used with an off-line integrated positive identity verification apparatus
that is capable of decoding the image and fingerprint samples taken from
an individual whose identity is sought to be verified.
