Anti-counterfeiting device, anti-counterfeiting recognition device and system for commodity packaging

Abstract

The invention belongs to the technical field of packaging anti-counterfeiting and discloses an anti-counterfeiting device, an anti-counterfeiting recognition device and a system for commodity packaging. Firstly, asymmetric encryption is performed on feature information containing commodity unique identification codes, a decryption public key corresponding to a encryption private key is implanted in encrypted ciphertext information to improve the encryption strength, corresponding encrypted two-dimensional code coded information is generated through the finally obtained ciphertext information, and the encrypted two-dimensional code coded information can be printed into a two-dimensional code label which is pasted at a seal of the commodity packaging through a printing device and can also be jet-printed at the seal of the commodity packaging through an ink jet printing device in a variable information printing mode. Simultaneously, the unique identification code of the commodity is printed on the commodity packaging in a plaintext mode. The plaintext information in the two-dimensional code label can be recognized and decrypted only through downloading corresponding two-dimensional code recognizing software in assigned service platforms and checking whether commodity unique identification codes accord with plaintext commodity unique identification codes on the commodity packaging, and the detection is convenient.

Description

Technical field [0001] The invention relates to the technical field of packaging anti-counterfeiting, in particular to a commodity packaging anti-counterfeiting device, anti-counterfeiting identification key device and system. Background technique [0002] The anti-counterfeiting of commodity packaging is a big issue involving the national economy and people's livelihood. A good packaging anti-counterfeiting solution has important social and economic value. [0003] At present, there are mainly the following methods in the application of packaging anti-counterfeiting, but from the consideration standards of low anti-counterfeiting cost, high imitation cost and convenient authenticity detection, each has some problems. [0004] 1) Packaging anti-counterfeiting technology based on special materials, such as anti-counterfeiting ink, laser holographic anti-counterfeiting, and heat-sensitive material anti-counterfeiting. This type of anti-counterfeiting method generally has high anti-cou...

AI Technical Summary

Problems solved by technology

This type of anti-counterfeiting method mainly has two problems: the pattern is produced in batches by templates, and the anti-counterfeiting information cannot be associated with the individuality of the packaged goods, which leads to the problem of low imitation costs; methods such as microprinting still have detection inconvenient disadvantage

Although such methods often increase the difficulty of counterfeiting, the cost of anti-counterfeiting is also increased a lot, and it is not convenient for authenticity detection
