Method for identifying cigarette authenticity based on self-encrypted self-checking two-dimensional code

Abstract

Disclosed in the invention is a method for identifying cigarette authenticity based on a self-encrypted self-checking two-dimensional code. A generation unit of a two-dimensional management unit generates a self-increasing serial number to generate a unique two-dimensional code; a printing unit prints the two-dimensional code at a designated position of a box skin package; a producing unit uses the box skin printed with the two-dimensional code to carry out cigarette packaging and uses a scanning device to scan a cigarette after primary packaging, the two-dimensional code that has been applied to production is recorded and is submitted to an activation unit (12) of a two-dimensional code management unit (1) to carry out activation processing; a user uses a scanning unit to scan the two-dimensional code printed at the internal package; an identification unit of the two-dimensional code management unit carries out decoding to obtain a serial number; and the identification unit of the two-dimensional code management unit carries out cigarette authenticity judgment according to the activation state of the serial number and the number of times of submission. According to the invention, a unique self-encrypted self-checking two-dimensional code is printed at each package of cigarettes, so that a consumer can use an intelligent terminal to scan the unique two-dimensional code at each package of cigarettes, thereby obtaining cigarette authenticity information simply, conveniently, and rapidly.

Description

technical field [0001] The invention relates to the fields of information security and automatic identification, in particular to a method for identifying the authenticity of cigarettes based on a self-encrypting and self-verifying two-dimensional code. Background technique [0002] Existing cigarette coding is generally a barcode, which has a small number of digits and less information content. It generally marks the year of production, sales area code, etc., which is not unique, easy to be forged, and cannot be effectively used for authenticity identification. The two-dimensional code can represent a wealth of information, and is easy to use, especially with the popularity of mobile smart terminals, two-dimensional code scanning has become a widely used method. Some companies print a unique QR code on each product to achieve product authenticity identification, product tracking, marketing activities and other purposes. However, two-dimensional codes generally use open tec...

Problems solved by technology

[0004] In order to solve the problem that it is difficult for consumers to judge the authenticity of cigarettes, a method for identifying the authenticity of cigarettes based on self-encrypting and self-verifying two-dimensional codes is proposed. The code information is difficult to forge, and at the same time, it can be directly judged whether the QR code is fake or not based on the QR code information
