Problems solved by technology

Another major weakness of multiple barcodes is the possibility of counterfeiting by third parties, which in turn can lead to damage to the user (e.g. replacement of product labels)

Embodiment Construction

[0055] attached Figure 1a Information unit 1 is shown. The information unit 1 here consists of icons or representations. An information unit may generally include all diagrams or two-dimensional imaging. Two dimensions are the two dimensions of the surface on which the information unit is constructed. The surface can be flat, such as a piece of paper or a poster. In addition, the surface may be curved, for example in the case of an advertising carrier. The two coordinates or dimensions may be referred to as x and y directions.

[0056] An information unit may also consist of one or more symbols, such as letters or numbers, or a combination of one or more symbols and one or more illustrations.

[0057] The information unit 1 is delimited by an outer contour 2 . This means that the outer contour 2 is the border or boundary line between the information unit 1 and the background. The background may be located on the same surface or arranged on another plane or surface.

Abstract

The invention relates to a method for encoding information into a graphic information unit (1), characterized by the steps of: determining the outer contour (2) of said information unit (1); and only in said outer contour ( 2) Information is encoded in at least one area (3) by means of at least one two-dimensional code (10), wherein the encoding is applied to the pixels (11a, 11b) of the information unit (1) .

Description

technical field [0001] The invention relates to a method for encoding information in a graphics information unit and a method for decoding information in an encoded graphics information unit. Background technique [0002] Starting in the field of logistics, many service fields, trade, for the identification of goods and people and in production and operation, the automatic identification method (Auto-ID) with the help of barcode technology has become more and more important in recent years. The mission and purpose of Auto-ID is to provide digital information about people, animals, goods and commodities. [0003] In addition to automatic identification, the so-called Mobile-Tagging (mobile label) especially provides a large range of applications for the new bar code technology. Three different fields are distinguished in Mobile Tagging: Commercial Tagging, for example in advertisements with additional information on products, direct downloads, direct links to web pages of co...
