Method for Information Extraction and Identity Identification by Recognizing Dot Matrix Graphics

Abstract

The invention provides a method for information extraction and identity authentication by identifying raster graphics. The method comprises the steps that the raster graphics are read, and obtained images are fed back; the fed-back images are automatically processed and placed in a cache; the images in the cache are analyzed and verified, so that code value information corresponding to the images is generated; information files corresponding to the code value information are found in a code value data base and extracted; the information files are decoded, so that multi-media files are formed, and the multi-media files correspond to the information files and comprise identity authentication information; the multi-media files are played, so that identity information of products corresponding to the raster graphics is obtained. According to the method, the raster graphics replace existing RFID labels and other modes, the method, the digital technique and the network technique are combined, and the method has the advantages of being low in printing cost, terminal manufacturing cost and enterprise operating cost, and achieving user inquiry mode convenience, and effectively achieves the effects of copying difficulty, low price and identifying convenience.

Description

technical field [0001] The invention relates to an anti-counterfeiting identification method, in particular to a method for extracting information and identifying identity by identifying dot matrix patterns. Background technique [0002] At present, the anti-counterfeiting technologies on the market are generally divided into ordinary anti-counterfeiting, electronic code anti-counterfeiting, DNA anti-counterfeiting, nuclear track, laser holographic anti-counterfeiting marking and OVD technology, ink anti-counterfeiting, anti-counterfeiting and anti-disclosure technology, RFID tags and security thread anti-counterfeiting. [0003] Yet the weak point of above anti-counterfeiting technology is as follows: [0004] 1. Ordinary anti-counterfeiting, there are problems such as insufficient query convenience, inability to save query results, inability to solve continuous queries, and easy dialing of wrong numbers by consumers; [0005] 2. Electronic code anti-counterfeiting, becaus...

AI Technical Summary

Problems solved by technology

[0004] 1. Ordinary anti-counterfeiting, there are problems such as insufficient query convenience, inability to save query results, inability to solve continuous queries, and easy dialing of wrong numbers for consumers;

[0005] 2. Electronic code anti-counterfeiting, because its technical content is not high, it has serious technical defects that are easy to be stolen and copied for batch copying, and it is easy to be used by counterfeiting gangs, resulting in anti-counterfeiting failure, which has a great negative effect on user companies influences;

[0006] 3. DNA anti-counterfeiting, its anti-counterfeiting uniqueness is high, but the price is expensive, so it occupies a very small market share, which is not conducive to consumers' direct inspection of the authenticity of products;

[0007] 4. The biggest disadvantage of nuclear track is that it can be used repeatedly. You only need to clean the mark drawn with a pen, and then you can use it again. It does not have the uniqueness of anti-counterfeiting label products, leaving a lot of trouble for counterfeiters. an opportunity to take advantage of;

[0008] 5. Due to the out-of-control management of laser holographic anti-counterfeiting marks and OVD technology, some inferior laser holographic marks and simulated marks have entered the market.

[0009] 6. Ink anti-counterfeiting, with the increase of anti-counterfeiting ink manufacturers, the effect of this anti-counterfeiting technology will not be able to prevent counterfeiting and shoddy;

[0010] 7. Anti-counterfeiting and anti-revealing technology, because there are many manufacturers, it is not unique, and it is not ruled out that manufacturers provide convenience for counterfeiters for profit;

[0011] 8. RFID tags are currently widely used in ticketing, electronics, jewelry and other industries, but they are expensive and not suitable for large-scale use in low-end commodities;

[0012]9. Safety thread anti-counterfeiting, because the country has very strict administrative and regulatory restrictions on paper mills in the production of safety thread paper, its application is also limited
