A method and system for encoding an object pattern code

Abstract

The present invention provides a method and system for encoding physical pattern codes. Using human fingerprint images as reference, on at least one preset fingerprint template, at least one fingerprint feature point is set on at least one fingerprint line to realize the encoding of numbers and / or letters , thereby forming a fingerprint pattern containing specific information, which can be used to code and identify products. When the fingerprint pattern contains specific coding information of an item and is formed on the item, it is unique like a human fingerprint. This kind of fingerprint pattern that uses feature points to express the specific identity information of an item is called an object pattern code. (Fingerprint of Thing, FOT). As a brand-new two-dimensional code derived from human fingerprint graphics, the object pattern code contains more information than the one-dimensional code, and solves the problem that the one-dimensional code cannot express the two-dimensional code and is too complicated. By using the coding method and system of the present invention, a physical pattern code containing unique identity information can be printed on each product, just like a human fingerprint, which remains unchanged for life and can be checked at any time.

Description

technical field [0001] The invention relates to the field of encoding technology, in particular to an object pattern code encoding method and system for encoding by referring to fingerprint feature points. Background technique [0002] With the rapid development of the commodity economy, the society has produced a large number of products, which need to be classified, identified, traced, and authenticated. In 1949, the one-dimensional barcode came out in the United States. In 1991, the two-dimensional barcode marked by the PDF417 code was proposed by Symbol Company of the United States. At present, the one-dimensional barcode and the two-dimensional barcode have been widely used in various fields. One-dimensional barcodes have a limited amount of information, while two-dimensional barcodes have a lot of information, but the problem is that the images of these barcodes are obviously different from the items they mark, usually appearing as a bar or square graphic block. One-d...

Problems solved by technology

[0035] In the existing technology, there is a lack of coding methods that require more information than one-dimensional barcodes but less than two-dimensional barcodes, and the graphics are more concise and clear, and can give people a natural sense of trust.

For the process of using human fingerprints, that is, the collection of fingerprint image codes and the encoding of fingerprint feature points are only used to compare whether the two fingerprint images match. There is no clear coding rule that specifically uses human fingerprint feature points. Actively construct fingerprint graphs containing specific information
