Abstract
A generic data package template is described that allows data to be encoded and printed in any arbitrary shape using an arbitrary encoding scheme. The template comprises an arbitrary shaped constant background pattern that is read to locate and orient a data area. The data are contains a plurality of dots that are decoded to extract the stored information.
Claims20
A tag format structure for generating a tag embedded with data and having a constant background pattern, the data and background pattern composed of dots within a bounding box, the tag format structure comprising:
- entries in the tag format structure corresponding to a position for each of the dots;
- the tag format structure having a first parameter corresponding to the width of the bounding box, in dots;
- the tag format structure having a second parameter corresponding to the height of the bounding box, in dots;
- the tag format structure having a third parameter corresponding to a number of bits in each entry;
- and
- the tag format structure having a fourth parameter corresponding to a number of data bits associated with a tag.
