Abstract
A machine readable code comprises at least a portion of a graphical indicium, the graphical indicium comprising a random arrangement of spots. At least some of the spots comprising the graphical indicium may have a dimension of less than one micrometre. The spots comprising the graphical indicium may vary in size and/or shape. The portion of the graphical indicium comprising the code may be delimited by a boundary, the boundary may be a temporary boundary which may be generated by a reading machine relative to a fixed trigger point only when the code is being read. Alternatively, the portion of the graphical indicium comprising the code may be delimited by a graphically represented boundary.
Claims15
A machine readable code comprising at least a portion of a graphical indicium, the graphical indicium comprising a random arrangement of spots.
A code according to any preceding claim, wherein the portion of the graphical indicium comprising the code is delimited by a temporary boundary that is generated by a reading machine relative to a fixed trigger point only when the code is being read.
A method of associating data with an article comprising the steps of:
- applying a graphical indicium comprising a random arrangement of spots to the article;
- acquiring electronically an image of at least a portion of the graphical indicium;
- processing the acquired image to produce a descriptor;
- assigning data to the descriptor;
- and,
- storing the association in a storage means.
An apparatus for associating data with an article comprising:
- an application unit for applying a graphical indicium comprising a random arrangement of spots to the article;
- a camera for acquiring electronically an image of at least a portion of the graphical indicium;
- a processor for processing the acquired image to produce a descriptor;
- an assignment means for assigning data to the descriptor;
- and,
- a storage means for storing the association.
