Anti-counterfeiting bottle cap based on security chip cryptographic algorithm and bottle cap activation and anti-counterfeiting method

Abstract

The invention relates to an anti-counterfeiting bottle cap based on a security chip cryptographic algorithm and an activation and anti-counterfeiting method. The bottle cap comprises a middle cap sleeving a bottom cap, a security NFC label and a switching value acquisition circuit connected with a port of the security NFC label are arranged in the bottom cap, label state marking parameters are stored in the security NFC label, and a cut-off mechanism is arranged on the middle cap; before the bottle cap is opened, an input circuit of the switching value acquisition circuit is intact, the middlecap can rotate relative to the bottom cap, and at the moment, the label state marking parameter is recorded as a state I and information corresponding to the state I is readable; in the process of rotating the middle cover, the cut-off mechanism causes irreversible damage to an input circuit, the security NFC label immediately modifies a label state marking parameter into a state II until the security NFC label cannot receive a switching value input signal any more, and information corresponding to the state II is enabled to be readable. According to the invention, anti-counterfeiting and bottle opening verification before and after cover opening are supported, the anti-counterfeiting performance is improved by adopting a complex security algorithm, and copying and playback are prevented.

Description

Technical field: [0001] The invention relates to the technical field of anti-counterfeit authentication, in particular to an anti-counterfeit bottle cap based on a security chip cryptographic algorithm and a bottle cap activation and anti-counterfeiting method. Background technique: [0002] With the improvement of people's living standards, high-value-added commodities are increasingly enriching the entire trading market, and these high-value-added commodities have gradually become the main target of illegal traders who make counterfeit prices. All kinds of counterfeit goods flowed into the market under the "coat" of genuine goods, which seriously disrupted the market order, brought serious economic losses to consumers, producers, and distributors, and also hindered the enthusiasm of enterprises for product research and development. Therefore, higher and more urgent demands are put forward for the development of commodity anti-counterfeiting technology. [0003] Commodity ...

AI Technical Summary

Problems solved by technology

Although it can also play a certain role in anti-counterfeiting and traceability, the technical threshold and production cost of these barcodes, two-dimensional codes, electronic codes, and laser labels are relatively low, and the anti-counterfeiting ability is also weak, so they are easily recycled by criminals for secondary use. The effect is greatly reduced

In order to achieve the purpose of preventing duplication and eliminating recycling and secondary use, there is a design method in the prior art that destroys the anti-counterfeit label by opening the cover, making it impossible to recover, but this structural design is relatively complicated, and the technical threshold for counterfeiters is not high. , the technical constraints are not strong, and there is still the possibility of counterfeit goods

[0004] Furthermore, the currently used anti-counterfeiting technology only provides a single anti-counterfeiting verification before opening the cap, does not support the second anti-counterfeiting verification after opening the cap, and cannot monitor whether the bottle cap has been opened (there is a risk of reusing the bottle cap after opening) , and the existing bottle caps do not have the function of uncapping and recording consumption information, which cannot enable manufacturers to timely grasp consumer consumption information (such as: the number of opened bottles to drink), cannot form effective commodity tracking records, and cannot provide consumers with Build bridges with manufacturers
