Double anti-counterfeiting system and method based on near field communication (NFC) function

Abstract

The invention discloses a double anti-counterfeiting system and method based on a near field communication (NFC) function. The double anti-counterfeiting system based on the NFC function consists of an electronic tag, handheld equipment with the NFC function such as a mobile phone or a customized handheld NFC reader and the like, application software with a random code generation function and a cloud database, wherein the electronic tag comprises a product identity coding fixed code, a product identity coding dynamic code and a product verification random code. All the random codes of the invention are generated by the application software with the random code generation function and inbuilt in the handheld equipment. The cloud database is only used for performing comparison and verification. The anti-counterfeiting implementation mode is that information communication between the cloud database and the electronic tag is realized by taking the handheld equipment as a medium. The handheld equipment serves as judgment equipment, so that the popularization is realized; an NFC chip of the electronic tag contains door passwords, a counterfeiter cannot acquire all the electronic tag information, and a double verification mechanism of a product identity coding dynamic code and a product verification random code is provided, so the possibility of large-scale counterfeiting is effectively avoided.

Description

technical field [0001] The present invention relates to a system and method for product identity identification and anti-counterfeiting, more precisely, it is a kind of application software with encoding function built in the handheld device through the use of handheld devices such as mobile phones or customized handheld NFC readers and other carriers. and NFC function, plus a cloud database and a specific electronic tag, a system for realizing product authentication, and a method for using the system. Background technique [0002] The traditional product anti-counterfeiting technologies currently on the market mainly include the following two types, one is a visual anti-counterfeiting mark processed by a special process, and the other is an anti-counterfeiting serial number that can be queried by telephone or the Internet. Defects. For the first anti-counterfeiting method, if a simple anti-counterfeiting mark is adopted, the difficulty of imitation is low, and it is easy t...

AI Technical Summary

Problems solved by technology

The use of complex anti-counterfeiting marks, although the difficulty of imitation has increased, can still be copied in large quantities once it is cracked, and requires users to have certain skills to identify the authenticity, which is not easy to use

The second way is that because the anti-counterfeiting serial number is easier to imitate in large quantities, most anti-counterfeiting inquiries can only inform the number of inquiries, and the query results are difficult to convince the public

Although it can effectively carry out anti-counterfeiting operations, there are some potential deficiencies: first, all dynamic information verification codes are generated by product identity digital inspection devices that exist on remote or cloud servers, that is, the verification device must not only For database comparison work, a new dynamic password needs to be generated. When tens of millions of products are queried at the same time, the system processes a huge amount of data, and there is a risk of system crash; second, the clear code used to obtain the read-write password is verified throughout the The process is immutable, which is not conducive to the protection of the read password and the protection of product information; the third point, for counterfeit products that can obtain the read password but cannot pass the dynamic code verification, each inspection needs to complete the entire verification process, and there is no first-time counterfeit , the function of simplifying the process and improving efficiency every time in the future

[0004] With the continuous popularization of handheld devices such as mobile phones and other devices, the NFC function of handheld devices is also gradually used in the field of anti-counterfeiting, such as the Chinese utility model patent authorization announcement numbers CN202976196U and CN202957830U, etc., but the whole system is relatively complicated and difficult to implement and maintain. It may not be easy to accept and difficult to promote
