Benefits of technology

"The present invention provides a machine-readable code for associating data with articles, which can be verified without obtaining the article data with which it is associated. The code has first and second parts that can be related or unrelated, and the relationship between the parts can be detected by a machine reading both parts. The code system includes a population of codes, each with unique first and second parts, and the relationship between the parts is detectable by a mathematical operation. The code system also allows for faster verification of the authenticity of a code by looking up the second part of the code in a database and then searching within a range for the unique first part. The invention provides a faster and more efficient way to verify the authenticity of a code and to associate data with articles."

Problems solved by technology

The code, which typically comprises a rectangular box delimiting a series of intersecting lines, Is difficult to copy to the degree of accuracy needed such that when read by a machine the same alphanumeric character string would be generated.
A further difficulty for would-be counterfeiters, is that many of the codes used are no more than 1 mm by 1 mm in area and may be printed in ultraviolet inks, infrared Inks or other security Inks.
Thus, without the algorithm, there is no way of deriving the information.

Embodiment Construction

[0026]Turning to FIG. 1, this shows generally at 10 a two-part code printed on a substrate 12. The two-part code 10 comprises a first part 14 and a second part 16 which are separated by a portion 12a of the substrate 12. In this case the first part 14 occupies a first, generally rectangular area and the second part 16 occupies a second, smaller generally rectangular area. The relative sizes of the first and second areas, and / or their shape, could be different from the example shown.

[0027]Inside the area occupied by the first part 14 is a plurality of straight lines, at least some of which intersect each other. In this example the first part of the two-part code comprises a composite indicium such as is described in our UK Patent No. GB 2383878 B and sold commercially under the trade mark FractureCode® and for which there is currently a co-pending U.S. application Ser. No. 10 / 383,185. Whilst the example is of a plurality of Intersecting lines, this type of code might comprise other e...

Abstract

A graphically representable, machine readable code having first and second parts wherein the first part may be associated with data and a second part may be associated with the first part, such that a relationship between the parts, or lack thereof may be discerned by reading both parts of the code, in order to verify the authenticity of the code.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This is a division of Ser. No. 11 / 542,300, filed Oct. 2, 2006 entitled “Two Part Code” which is a National filing of a corresponding co-pending application filed in the United Kingdom as U.K. Serial No. GB05200654, filed Oct. 3, 2005, entitled “Two Part Code” for which priority is claimed and which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to codes and is concerned particularly with codes having two parts, which two parts are related.[0003]Graphic, machine-readable codes are commonly used, for example, to identify articles such as consumer products. Several popular codes are currently used, including one and two-dimensional barcodes and matrix-style codes. In each case the code is applied to an article and enables the article to convey information about itself such as the identity of the manufacturer, and the article type.[0004]One sophisticated type of machine readable code is desc...
