Abstract
A method to encode and decode a digital fingerprint code by an identification encoder and an identification decoder wherein the digital fingerprint code includes a plurality of N-bit data embedded on a set of curves by changed thicknesses in the curves.
Claims7
A decorative workpiece comprising:
- a wood pattern including an inkjet printed identification code to track-and-trace the decorative workpiece;
- wherein
- the inkjet printed identification code is embedded in nerves in the wood pattern;
- the inkjet printed identification code includes a plurality of N-bit data that represent content;
- the plurality of N-bit data includes first N-bit data (N1) and a different second N-bit data (N2) on one of the nerves;
- and
- a thickness (TN,i,1) of a value (vN,1) from the first N-bit data (N1) on the nerve is different from a thickness (TN,i,2) of a value (vN,2) from the second N-bit data (N2), and/or a length (LN,i,1) of the value (vN,1) from the first N-bit data (N1) on the nerve is different from a length (LN,i,2) of the value (vN,2) from the second N-bit data (N2).
